Introduction of silicone material

Sources:本站 Date:2015-12-28 

Silica gel is environmental protective, so more and more people love it. At present, there are more and more things using silica gel as ingredient, our company - Shenzhen Hengbinli Technology Co., Ltd is a professional producer of silicone products. If you are interested in our products, let me know. To systematically understand our products, you need first understand the raw material.


Silica gel (gel Silica; Silica) is a highly active adsorbent material, amorphous material. Its chemical formula is mSiO2 nH2O; except alkali, hydrofluoric acid, it will not react with any substance, insoluble in water and any solvent, non-toxic and tasteless, stable in chemical property. Various types of silica gel formed different microporous structures due to different manufacturing methods. The chemical composition and physical structure of the silica gel determined that it has many other merits that irreplacable from similar materials, such as high adsorption capacity, good thermal stability, stable chemical property, high mechanical strength and so on. According to the silica gel pore size,it can be divided into big pore silica gel, porous silica, silica gel B, kiselgel etc..


1 silicone raw materials can be divided into domestic and imported materials according to the source.

Domestic materials mainly include: dongjue, Rui Ying, HTC, Tian Yu, New Oriental, manufacturers and other large polymerization.

Imported materials mainly include: Shin-Etsu, Toshiba, Dow Corning, French Rodia, Wacker etc..




2 silicone raw materials according to the performance can be divided into ordinary silica gel and silica gel weather

Also known as ordinary silica silica gel precipitation

Color: transparent, 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%

Use: our company use low conductive adhesive silicone products on mobile phone keys, sundries, etc..

The weather also known as pure silica gel 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 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, protective sleeve and other high-end needs of high elastic products.




3 silicone raw materials can be divided into solid and liquid silicone gel according to the physical properties.

Solid silicone is mainly used for molding products. Such as silica gel covers, 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. Our company focus mainly on molding and molding of silicone products, such as silicone buttons, silicone sets, silica gel tableware, etc.. People who have demands in this area are welcomed to call or write to negotiate at any time. And we welcome our  old and new customers to the factory for inspection at any time. Our address is: Baoan District province Guangdong City Shajing town Buyong Community Industrial Road No. 2 Building 3.广东省深圳市宝安区沙井镇步涌社区工业路2号3栋
