Rubber and plastic board is also known as rubber and plastic insulation board. It is a thermal insulation material made of rubber and plastic. Because of its excellent properties of cold resistance, heat resistance, flame retardancy and flexibility, it is widely used on the surface of various pipes or containers to achieve thermal insulation protection. The fire safety coefficient of rubber and plastic insulation pipe foam is relatively high. It is characterized by large rigidity, light capacity, good thermal insulation and dimensional stability. Rubber and plastic insulation board is thermal insulation material. It has the characteristics of light unit weight, small thermal conductivity, impermeability, small water absorption, non combustion, non mildew, high mechanical strength, convenient processing, chemical corrosion resistance (except hydrofluoric acid), non-toxic, stable performance, both cold insulation material and thermal insulation material, and can adapt to the range from deep cold to higher temperature. At the same time, its important value is not only that it will not deteriorate after years of use, but also plays a role in fire prevention and earthquake prevention. It is not only safe and reliable, but also durable when used in low temperature and deep cold, underground engineering, flammable and explosive, humid and harsh chemical corrosion environments
