Gas phase rubber is also called pure silica gel: high transparent appearance, tensile strength of 7.8-10.0mpa, elongation of 500-1000%, tear strength of 29.4-49kN /m, the product after vulcanization molding will not appear when stretching whitening phenomenon, how to pull will not be white, and can be pulled very long. Production is the use of silicon tetrachloride and air combustion of silica, fineness of more than 1000 mesh, used for food grade silicone tube, medical grade silicone tube with special requirements.

Gas phase is also called the high strength of silicone rubber, the main production of high transparent silicone products, liquid silicone compared with ordinary silica gel to make high elastic rubber, high toughness, and the compression deformation of the buffer is low, high resistance to yellow effect of products, the gas phase method of silica gel is the use of silicon tetrachloride and air combustion proceeds made of silica gel, silica fineness of more than 1000 mesh. And the difference is the precipitation method of silica gel, its production is the use of sodium silicate after adding sulfuric acid to precipitate silica. Fineness is only 300-400 mesh.

1. Gas phase rubber and mixed silicone rubber can use double 25 vulcanizing agent and odorless vulcanizing agent, and the vulcanizing molding process between the two is basically the same

2. Gas phase rubber and mixed silicone rubber have excellent high and low temperature resistance, can be used for a long time at -60°C to 250°C temperature environment;

3. Gaseous rubber and mixed silicone rubber have excellent chemical stability and are not easy to react with acid, alkali and salt substances;

4. Gas phase rubber and mixed silicone rubber have non-toxic and tasteless characteristics, and can fully meet the food-grade testing standards;

5. The hardness between the two is the same, generally used hardness between 20 degrees -80 degrees.
