Today we will bring you the material of silicone seal ring. We hope you can have a deeper understanding through our introduction

Silicone sealing ring material

Silica gel is more and more popular because of its environmental protection. To understand the knowledge of silica gel products, it is necessary to start with silica gel raw materials.

1. Silica gel raw materials can be divided into ordinary silica gel and meteorological silica gel according to their performance

Ordinary silica gel is also known as precipitation silica gel

Color: translucent, milky white, light yellow, gray, etc.

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

Density: 1.1 to 1.12 g/c ㎡

Elongation rate: 400%

USES: the most commonly used is the mobile phone keys, miscellaneous parts, conductive adhesive and other low - grade silicone products.

Weather gel also known as pure silica gel

Color: transparent.

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

Features: good transparency and strong tensile resistance. The cost is high

Application: silicone tube, protective cover and other high - grade products need high elasticity.

2. Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to their physical properties.

Solid silica gel is mainly used in molding products. For example: silica gel set, silica gel tableware, silica gel buttons, etc., liquid silica gel is mainly used for extrusion molding products, such as silica gel nipple, silica gel tube, etc.

Insulation silicone pad, excellent high temperature resistance, silica gel (food grade silica gel) can withstand the high temperature of 200℃ and can be used for a long time, the product raw materials meet the SGS standard, passed the FDA food grade silica gel test standard, tasteless and non-toxic, manufacturers according to the production model of sealing ring, silicone seal ring material color, shape can be determined.
