What kind of thermal insulation material is good for central air-conditioning installation? At present, there are several commonly used materials in the market, including rock wool, glass wool, PEF thermal insulation cotton (polyethylene) and rubber plastic thermal insulation materials. The first two materials are seldom used by many companies due to some reasons of the product itself (irritation and itching after human contact). However, the product has price advantages compared with other thermal insulation materials, so some projects in the market will use it, And PEF thermal insulation cotton and rubber and plastic thermal insulation materials are new environment-friendly building engineering materials that are widely used in the market at present, and many people use them. Especially in the installation of central air conditioning, there are many choices. Usually, many companies prefer to use PEF insulation materials for air ducts and rubber and plastic materials for water pipes. Some companies prefer to use one of these materials, depending on the habits of each company. At the same time, many new thermal insulation materials are also being applied and promoted in the market.

Performance analysis of PEF foam insulation material:

1. Non toxic>No toxic substances. During high-temperature decomposition, no harmful gas will be generated;

2. Weather resistance>Due to high crosslinking degree and good stability, the surface layer has no change after 300 hours of artificial ultraviolet radiation, and the service life is long;

3. Corrosion resistance>It can resist a variety of chemicals, and basically does not deform or crack after immersion, so it can be widely used for thermal insulation of chemical pipelines and storage tanks;

4. Cushioning property>impact resistance and cushioning property are the best for other thermal insulation materials;

5. Low temperature resistant type>The material does not change under the conditions of - 100 ℃ to - 196 ℃, which is very suitable for refrigeration. It is used as thermal insulation material in the air conditioning industry.
