rubber foam insulation

As a leader in China's rubber and plastic products, in this article Hairui Rubber will take you to understand the “invisible guardian” of the excellent application value. Rubber insulation materials as building energy saving, industrial pipe insulation and precision equipment protection in the field of star materials, by virtue of its “thin to see thick” characteristics, is quietly changing the human perception of energy-saving technology. The definition and material composition: the mystery of the elastic closed-cell structure Rubber insulation material is made of high-quality rubber (NBR) and polyvinyl chloride (NBR/PVC) as the main raw material, through the mixing, refining, heating and foaming, continuous extrusion and other processes made of elastic closed-cell foam. Its internal uniform distribution of fine closed-cell structure, not only to isolate the heat transfer, but also to resist water vapor infiltration, while both flexibility and durability. In addition, it is easy to construct, has a neat and beautiful appearance, and the product does not contain fiber dust, which will not breed mold and other harmful substances. This material combines the elasticity of rubber with the stability of plastic, and is regarded as “the representative of a new generation of insulation materials” by the industry.   The core performance advantages Low thermal conductivity Rubber is a high-quality thermal insulation and energy-saving materials, cold insulation, heat insulation and anti-condensation nemesis, low thermal conductivity and remain stable, on any heat medium to isolate the effect. Rubber plastic thermal conductivity as low as 0.032-0.033 W/m-K (average temperature 0 ℃), only 1/3-1/2 of the traditional thermal insulation materials. average temperature of 0 ℃, the thermal conductivity of the rubber plastic insulation materials can be as low as 0.033w/mk, and its surface heat release coefficient is high, so in the same external conditions, the use of rubber plastic insulation materials, about half of the thickness of the other thermal insulation materials, which means that a thinner thickness can be used to insulate any heat medium. This means that the use of thinner thickness can achieve the same thermal insulation effect, especially suitable for space-constrained ceiling piping or precision equipment, can save installation space of more than 50%.   Good fire resistance and flame retardant properties Through the GB8624 B1 class flame retardant certification, to protect the safety of the fire environment. Rubber insulation material contains a large number of flame retardant smoke-reducing raw materials, in case of fire does not melt drop, does not spread, burning smoke concentration is very low, leaving the source of fire quickly and automatically extinguished, to ensure safety and reliability.   Waterproof and moisture-proof: Rubber is a closed-bubble structure, water in the outside air is difficult to penetrate into the material, with excellent resistance to water vapor permeability, cold insulation layer appearance without adding vapor barrier. Adopting fine control micro-foaming technology, the bubble rate of closed cell greatly increased, but also more uniform and dense, strong resistance to water vapor permeability, to extend the service life. Even if the surface scratches can still maintain the overall moisture resistance, no need to add additional vapor barrier. Rubber is both thermal insulation and moisture barrier.   Environmental health: Rubber insulation material is very safe to use, first of all, rubber does not contain chlorofluoride harmful to the atmosphere, in line with the ISO14000 international environmental certification requirements, and secondly, rubber materials, no fiber dust, neither stimulate the skin, but also does not endanger the health, at the same time, they can prevent the growth of mold, so in the installation and application of pollutants will not produce any harmful to the human body.   Engineering friendly characteristics: The material is soft and easy to bend, can be tightly wrapped valves, elbows and other complex components, construction without specialized tools, support for cutting and gluing or direct sets, greatly enhancing the installation efficiency. Its elastic structure can also absorb pipeline vibration and noise, extending the life of equipment.   As a crystallization of modern engineering science, rubber insulation material to “thin” see “thick” - with a thinner form to carry more powerful functions, for the sustainable development of mankind provides a Energy efficient solution path. Whether it is the skyscraper's “invisible coat”, or precision pipeline “temperature guard”, it is in the silent interpretation of science and technology and nature's harmonious coexistence.   If you want to know about the rubber insulation material products and knowledge, please continue to pay attention to us.

In daily life and industrial production, we often hear the word “rubber and plastic”, but in the end rubber and plastic products are rubber or plastic? This is a confusing question, because the rubber and plastic at the same time with the characteristics of rubber and plastic, so that it is difficult to simply categorized.     In fact, rubber and plastic is not simply rubber or plastic. It is a rubber and plastic as the main component, and add a variety of additives with the composite material. This composite material has some of the characteristics of rubber, such as high elasticity and good abrasion resistance, but also has some of the advantages of plastic, such as easy processing, molding and stable chemical properties.   So, how to distinguish between rubber and plastic materials and simple rubber and plastic?   First of all, from the point of view of chemical composition, rubber and plastic components of rubber-plastic materials are usually co-mingled or cross-linked, forming a complex foam closed-cell structure. This structure makes the rubber-plastic material has both the elasticity of rubber and the stability of plastic. Secondly, from the physical properties, rubber-plastic materials usually have excellent abrasion resistance, anti-aging properties, electrical insulation, thermal insulation and other characteristics, these properties are often better than a single rubber or plastic materials.   Rubber-plastic materials have been widely used in many fields due to their unique properties. For example, in the field of construction, rubber-plastic materials are used to make thermal insulation materials, waterproof materials, soundproofing materials, etc.; in the electronic field, rubber-plastic materials are used to make electronic components shells, connectors, etc.; in the automotive field, rubber-plastic materials are used for the production of tires, seals, shock absorbers and so on.   For ordinary consumers, understanding the nature and characteristics of rubber and plastic materials help to better choose and use related products. When buying rubber and plastic products, you can pay attention to the material, performance and production process and other aspects of the information to ensure that the purchase of reliable quality and excellent performance of the product. At the same time, the environmental protection and sustainability of rubber and plastic materials is also very important to pay attention to, which helps to promote the whole industry to a more environmentally friendly and sustainable direction.   Rubber plastic is neither pure rubber nor pure plastic. It is a composite material that combines the advantages of rubber and plastic, with unique properties and a wide range of application prospects.

Rubber and plastic is the rubber and plastic industry, they are all petroleum products, they are the same in the source, but in the process of making products, physical properties are not the same, the use is different, rubber is used for a wide range of tires, plastics in the demand for technology and the market and the use of more and more extensive, in daily life has been inseparable from the head. Long-term exposure to rubber and plastic products is very harmful to human health, many children like to put this aroma of heavy, colorful erasers in the mouth to chew, children's resistance is relatively weak, so the harm is great. Plastic production pollution costs are very high, especially for air pollution, emissions pollution caused by a very large impact, and emissions of gas and sewage are with very pungent chemical components, the production process produces black smoke with highly toxic. Rubber plastic is also divided into two kinds: natural rubber plastic and synthetic rubber plastic, synthetic rubber plastic also has pollution emissions with toxic; and now the state advocates the use of natural rubber plastic to process, natural rubber plastic system as zero pollution and zero emissions, just in line with the current low-carbon life of the international issues, but the natural rubber plastic for the two kinds of performance differences.

How is the sound insulation effect of rubber and plastic insulation boards? Today, we are going to introduce the sound insulation function of rubber and plastic insulation boards. Maybe many people will ask, can the insulation effect be achieved by wrapping rubber and plastic insulation boards? Let's take a look together! Firstly, the sound absorption performance of rubber and plastic insulation boards is closely related to the physical structure of the product itself. Due to the tightly foamed structure and elastic surface of rubber and plastic insulation boards, they have a good effect on reducing external sounds. However, in the actual use of rubber and plastic insulation boards, many environmental factors determine the sound insulation and noise reduction effect of rubber and plastic insulation boards. For example, their thickness and density, as well as the air flow resistance, have a significant impact on sound insulation and noise reduction. Air flow resistance is usually the ratio of the air pressure on both sides of the material per unit thickness to the air flow between the two sides. It also affects the sound absorption efficiency of rubber and plastic insulation boards. If the flow resistance is too small, it indicates that the structure of the entire material is very loose. Noise is particularly easy to pass through this material during the process of air vibration, thus resulting in a decrease in sound absorption and noise reduction performance. Let's take an example: for instance, rubber and plastic wave cotton or rubber and plastic egg cotton processed from rubber and plastic insulation boards. A friend asked us to wrap this product around the sewer, but the effect was not good. The wavy shape of high-quality rubber and plastic egg cotton is an important factor in determining the sound insulation effect of the product. The concave and convex shapes and dense open-cell bubbles refract sound waves to achieve the effect of reducing sound. If the wrapping method is chosen, the rubber and plastic insulation board manufacturer suggests using thickened rubber and plastic boards with adhesive on the back. Because to fully utilize the excellent noise reduction characteristics of rubber and plastic insulation boards, the thickness should be determined based on the actual situation. Therefore, we can conclude that when using rubber and plastic egg cotton for sound insulation, the rubber and plastic insulation board should be made into a concave and convex surface to face the sound source. Noise is harmful to people, and noise reduction is to isolate the sound source within the range that the human body can tolerate, and rubber and plastic insulation boards are important materials in the process of noise treatment. Another point is to increase the thickness of rubber and plastic insulation boards. As the thickness of rubber and plastic insulation boards gradually increases, the sound absorption coefficient of some medium and low frequencies will gradually increase, but the high-frequency sound absorption coefficient changes little. When the total weight of the entire rubber and plastic insulation board increases, their low and medium-frequency sound absorption coefficients will gradually increase. As the total weight increases to a certain extent, the structure of the rubber and plastic insulation board will become particularly dense, and the overall sound absorption efficiency will gradually improve. It can be seen that in the actual use effect of rubber and plastic insulation boards, the sound absorption coefficient and sound absorption performance of different sounds are directly related to them. If their bulk density is high, the sound absorption performance will decrease. Because the material becomes particularly dense, it will have a significant impact on their use effect. A quiet environment brings people a better living or living experience. Rubber and plastic insulation boards are the best choice for sound insulation and noise reduction in building materials!
