Yuhuan County Truman plastic products factory to introduce you to silicone seal materials:

Silica gel has become more and more popular because of its environmental protection performance. To understand the knowledge of silicone products, have to start from the raw materials of silica gel.

1, silicone raw materials can be divided into ordinary silica gel and weather

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, and so on, commonly used in 40 degrees -70.

Density: 1.1-1.12g/c square meters

Elongation: 400%

Usage: use is more mobile phone keys, sundries, etc. low conductive adhesive silicone products.

Meteorological 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 -60.

Density: 1.1-1.12g/c square meters

Elongation: 600%-700%

Features: due to the transparency of this material is good, strong anti tensile. High cost

Purpose: silicone tube, protective sleeve and other high-end needs of high elastic products.

2, silica gel 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 silica gel, silica gel tableware, silicone keypad, such as, liquid silicone rubber is mainly used for extrusion molding products, such as silicone nipple, silicone tube.

Silicone insulation pad, excellent resistance to high temperature, silica gel (food grade silicone) can be resistant to high temperature of 200 DEG C and can be used for a long time, the raw material for the production with SGS standards, through the FDA food grade silicone testing standards, non-toxic and tasteless, manufacturers according to the mode of production, color, shape, can be customized.
