Brief Introduction of Silicone Rubber Raw Materials
Silicone rubber is more and more popular because of its environmental protection performance. Now more and more other materials in the market have been replaced by silicone rubber products. If you want to know more about silicone rubber products, you must start with silicone rubber raw materials.
1. Silicone rubber raw materials can be divided into domestic materials and imported materials according to their sources.
2. Silicone rubber raw materials can be divided into ordinary silicone rubber and gas phase silicone rubber according to their properties.
Ordinary silicone rubber, also known as precipitated silicone rubber
Colour: translucent, Milky white, light yellow, grey, etc.
Hardness: 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, commonly used between 40 degrees and 70 degrees.
Density: 1.1-1.12g/cm2
Elongation: 400%
Usage: Used in mobile phone buttons, sundry parts, conductive rubber and other low-grade silica gel products.
Vapor phase silicone rubber, also known as pure silicone rubber
Colour: Transparent.
Hardness: 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, commonly used between 40 degrees and 60 degrees.
Density: 1.1-1.12g/cm2
Elongation: 600%-700%
Characteristic: Because this material has good transparency and tensile strength. The cost is on the high side.
Usage: Silicone rubber pipe, protective sleeve and other high-grade products which need high elasticity.
3. Silicone rubber raw materials can be divided into solid silicone rubber and liquid silicone rubber according to their physical properties.
Solid silicone rubber is mainly used for moulding products. For example: silicone sleeve, silicone tableware, silicone rubber buttons and so on, liquid silicone rubber is mainly used for extrusion products, such as silicone rubber nipples, silicone rubber tubes and so on.
