　　Silicone increasingly favored by the people because of its environmental performance. Replaced by other materials on the market,more and more products chanting silicone products to understand the knowledge of silicone products, was start from silicone raw materials.

　　1, silicone raw material according to the performance points can be divided into ordinary silica and meteorological silicone

　　The ordinary silicone also known as precipitated silica gel

　　Color: translucent, milky white, pale yellow, gray and so on.

　　Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, etc., commonly used in between 40 ° -70 °.

　　Density :1.1-1 .12 g / c ㎡

　　Elongation: 400%

　　Purposes: the more phone keys, miscellaneous items, conductive adhesives, middle and low silica gel products.

　　Weather plastic, also known as pure silicone

　　Color: transparent.

　　Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly between 40 ° -60 °.

　　Density :1.1-1 .12 g / c ㎡

　　Elongation: 600% -700%

　　Features: good transparency of this material, strong tensile. High cost

　　Usage: silicone tube, protective sleeve upscale require high flexibility of the product.

　　2, silicone raw material according to the physical properties of points can be divided into solid silicone and liquid silicone.

　　Solid silicone is mainly used for molding products. Such as: silicone cover, silicone tableware, silicone keys, liquid silicone ismainly used for extrusion molding products, such as silicone nipples, silicone tube

　　Insulation silicone pad, excellent high temperature silicone (food-grade silicone) resistant to 200 ° C high temperature and long-term use, the production of raw materials in line with SGS standard tasteless and non-toxic, FDA food grade silicone testing standards, in accordance with the manufacturers mold production, color, shape can be customized, inquire for details.
