Silicone products are more and more widely used nowadays because of its superior environmental performance and increasing popularity. Silicone raw materials can be divided into ordinary silicone and gas phase silicone according to its performance. So when doing silicone products, if you go to distinguish the raw materials used is ordinary rubber or gas phase rubber? What is the difference between them? What are the advantages and disadvantages? Let Srtub bring you together to learn how to recognize.

China Factory Adhesive 1mm Waterproof Natural Black Nitrile Epdm Sbr Elastic Thin Soft Oil Resistant Nonslip Silicone Rubber Sheet Roll

1. Ordinary silicone (referred to as ordinary rubber), also known as precipitated silica gel: opaque or translucent appearance, tensile strength of 4-6.9Mpa, elongation 150-300%, will be vulcanized after the molding of the product will be obviously white when stretching, and tensile properties of the general, can not be very long. Because of the lower cost, larger dosage, mostly used for industrial silicone tube.

2. Gas phase silicone (referred to as gas phase rubber), also known as pure silicone: highly transparent appearance, tensile strength of 7.8-10.0Mpa, elongation of 500-1000%, tear resistance, tear strength of 29.4-49KN/m, will be vulcanized after the molding of the product will not be white phenomenon, how to pull it will not be white, and because of the resistance to stretching, it can be pulled for a long time. Production is the use of silicon tetrachloride and air combustion of silicon dioxide obtained from the fineness of 1000 mesh or more, mostly used for food grade, medical grade and other special requirements of the silicone tube.

As the fumed rubber than ordinary rubber production of silicone rubber cost is high, so the same hardness fumed rubber tensile tear elongation, etc. better than ordinary rubber, its environmental protection index is also higher.

Vapor phase rubber characteristics:

1, high and low temperature impact resistance
2, fast vulcanization
3, very low odor; the release of the vulcanization process is harmless to the human body
4, bonding with a variety of substrates without the use of primer
5, excellent heat resistance, ozone resistance and chemical resistance
6, excellent electrical insulation properties
7, single-component system is simple and convenient to use
