Silicone products raw materials basic knowledge.
Silicone products in the market, we are not unfamiliar, but what is the play of silica gel, may not understand, so today we simply know what the silica gel, silica gel from the first understanding of silica gel raw materials from the beginning:
1 silicone raw materials can be divided into domestic materials and imported materials according to the source.
Domestic materials mainly include: dongjue, Rui Ying, HTC, Tian Yu, New Oriental, manufacturers and other large polymerization.
The imported materials mainly include: Shin-Etsu, Toshiba, Dow Corning, French Rodia, Wacker etc..
2 silicone raw materials can be divided into ordinary silica gel and weather silica gel
Common silica gel, also known as precipitated silica
Color: translucent, milky white, light yellow, gray, etc..
Hardness: 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, and so on, commonly used in 40 degrees - 70 degrees.
Density: 1.1-1.12g/cm2
Elongation: 400%
Usage: use is more mobile phone keys, sundries, etc. low conductive adhesive silicone products.
Meteorological silica gel, also known as pure silica gel
Color: transparent.
Hardness: 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, and so on, commonly used in 40 degrees - 70 degrees.
Density: 1.1-1.12g/cm2
Elongation: 600%-700%
Features: due to the transparency of this material is good, strong anti tensile. High cost.
Purpose: silicone tube, cell phone protection sets and other high-end needs of high elastic products.
3 silicone raw materials according to the physical properties of the points can be divided into solid silica gel and liquid silica gel.
Solid silica gel is mainly used for molding products. Such as mobile phone sets of silica gel, silica gel tableware, silicone keypad, and so on, liquid silicone rubber is mainly used for extrusion molding products, such as silicone nipple, silicon rubber hose and so on.
