Elastomeric绝缘材料

This product is an aperture-closing elastic material has such perfect performances as soft, anti-bending, cold-resistant, heat-resisting, fire-blocking, water-proof, low thermal conductivity, chock absorption and sound-absorption. This material contains a lot of fire-blocking and smoking-reducing raw materials. The smoking concentration generated from fire is very low. It shall not be melted when touched with fire and no any burning balls will be fallen down. The material has self-extinguishing characteristic. It can be widely used for every kind of cold/ hot medium piping and containers in central control air condition, construction, chemical industry, medicine, light industry, textile process, metallurgy, boat, vehicle, electrical apparatus and other fields to reduce cold/thermal loss. In addition, because this product is easy to be installed, has beautiful book and never has any pollution, therefore, it is a new generation high quality heat-insulating, and heat-preservation material.Foam rubber technical properties.
