Rubber and plastic thermal insulation material is a kind of excellent thermal insulation, flame retardant, sound-absorbing thermal insulation performance material, its combustion performance is B1 grade flame retardant and B2 grade combustible. Some people think that refractory B1 grade rubber and plastic insulation material is composed of B2 grade rubber and plastic composite other materials, so that it reaches B1 level; Or it could be a composite itself. In fact, is this really the case?

Composite materials are composed of two or more materials with different properties, through physical or chemical methods, and have new properties in the macro. This combination makes the composite material have excellent properties in mechanics, heat, electricity and other aspects that a single material does not have.

The main raw materials of rubber and plastic insulation materials are rubber and plastic, and there are more than 20 kinds of auxiliary materials. These materials are made by mixing, mixing, continuous extrusion, heating foaming, cooling scuttling and other processes. In this process, so the material is tightly combined to form a uniform insulation material. Because the ratio of materials and materials are different, B1 grade refractory rubber and B2 grade combustible rubber and plastic will be produced.

Therefore, the refractory B1 grade rubber and plastic insulation material is not made of B2 grade rubber and plastic composite other materials. In addition, composite materials emphasize the combination of two or more materials with different properties to produce new properties. Although refractory B1 grade rubber and plastic insulation materials contain a variety of different components such as rubber and plastic, these components do not maintain their original independent properties in the manufacturing process, but form a whole.

At present, the more common rubber and plastic insulation composite material is aluminum foil veneer rubber and plastic insulation material. It is compounded with a layer of aluminum foil on the surface of the rubber and plastic insulation material, which can improve the insulation effect and enhance the fire resistance in the performance of the rubber and plastic insulation material, and can also act as a protective layer from the damage of dust, water vapor, sharp objects, etc.

Refractory B1 grade rubber and plastic insulation material is not composite material, which itself has refractory properties. In practical applications, it can be combined with other materials to form a composite material system to meet the needs of different fields.
