The high temperature resistance of rubber foam insulation board can reach about 105℃ without damage. The foam insulation material is an elastic closed-cell elastic material, which is soft, resistant to bending, cold, heat-resistant, flame-retardant, waterproof, low thermal conductivity, shock absorption, sound absorption, etc. Excellent performance, can be widely used in central air conditioning, construction, chemical, textile, metallurgy, transmission, vehicles, electrical appliances and other industries and various types of cold and heat medium pipes and containers, and can achieve the effect of reducing cold and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and will not breed any harmful substances such as mold, so it is a high-quality thermal insulation material.
