What is rubber and plastic insulation material?

As a high-performance thermal insulation and energy-saving materials, with its unique physical properties and a wide range of applications, rubber-plastic insulation material has become an indispensable “invisible guardian” in the fields of chemical industry, construction, transportation and so on. This green material has excellent value.

First, the definition and material composition

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 foam, 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 penetration, 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.

Second, the core performance advantages

1. Low thermal conductivity

Rubber is a high-quality thermal insulation and energy-saving materials, is the nemesis of cold insulation, heat insulation and anti-condensation, 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%.

2. Good fireproof and flame retardant performance

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 fire source quickly and automatically extinguished, to ensure safety and reliability.

3. Waterproof and moisture-proof: rubber is a closed-bubble structure, it is difficult for water in the outside air to penetrate into the material, it has excellent resistance to water vapor permeability, the cold insulation layer appearance does not have to add a 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 plastic is both thermal insulation and moisture barrier.

4. 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, the rubber material is free of fiber dust, neither stimulate the skin, but also will not endanger the health, at the same time, they can prevent the growth of mold, so in the installation and application will not produce any harmful pollutants.

5. 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, prolonging the life of the 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.
