Classification and characteristics of silicone raw materials

Jan 24, 2022

Silicone tube strips and silicone shaped tube strips can be divided into extruded tubes and shaped tube strips. It is mainly made of silica gel, also known as raw silicone rubber, added to a double-roll rubber mixing machine or a closed kneader, and white carbon black and other additives are gradually added to make the product uniformly through extrusion according to the technical standards of the industry.
Because of its unique environmental protection characteristics, silica gel is becoming more and more popular among people, and it is gradually replacing other material products, such as kitchen utensils, baby products, and other products that are closely related to people's lives!
1. Silicone raw materials can be divided into domestic materials and imported materials according to their sources.
2. According to performance, silica gel raw materials can be divided into ordinary silica gel and meteorological silica gel.
Ordinary silica gel, also known as precipitated silica gel
Color: translucent, milky white, light yellow, gray, etc.;
Hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40°-70°;
Density: 1.1-1.12g/cm2;
Elongation: 400%;
Purpose: The most used are mobile phone buttons, miscellaneous parts, conductive glue and other low- and medium-grade silicone products.
Meteorological silica gel, also known as pure silica gel
Color: transparent; hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40°-60°;
Density: 1.1-1.12g/cm2; elongation: 600%-700%;
Features of silicone tube: Because this material has good transparency and strong tensile strength. High cost;
Uses: Silicone tubes, protective sleeves and other high-end products that require high flexibility.
