What are the characteristics of foamed silicone
Time:2019-12-02
Foamed silicone rubber is an elastic and environmentally friendly material, which has the characteristics of water resistance, weather resistance, aging resistance, non-toxicity and tastelessness, etc., and is welcomed in the construction industry.

In a general sense, foam rubber refers to polyurethane foam, which is the combination of aerosol technology and polyurethane foam technology. Foam rubber is a special polyurethane product made by filling polyurethane prepolymer, foaming agent, catalyst and other components into a pressure-resistant aerosol can. As a polyurethane product, foam rubber has some common problems of polyurethane products, such as flammable, and it will produce heavy black smoke when burning. Therefore, foam rubber should be kept away from fire and heat sources, and stored in a dry, cool and ventilated environment according to requirements. The storage temperature should not exceed 30 ° C.

With the advancement and development of technology, the upgrading of products and the emergence of foamed silica rubber have set off a wave in the industry. Foamed silica gel is also called addition-molded silica gel. It is a heated vulcanized silicone rubber. It is composed of silica gel and curing agent in a ratio of 1: 1. After curing, it forms a soft elastic material. The later emerged liquid foamed silica gel is an environmentally friendly material that has passed SGS environmental protection non-toxic certification. Foamed silica gel has excellent electrical properties and chemical stability. It is also resistant to water, weather, aging, non-toxic and tasteless, low linear shrinkage, and easy to install. Foamed silica gel has uniform foam pore size, light weight, high elasticity, and good feel. It is commendable that it does not cause migration.
