First point: high temperature resistance
Suitable temperature range - 40 to 230 degrees Celsius, can be used in microwave ovens and ovens. So some lunch boxes and bowls are made of silica gel.
Second point: easy to clean
The silica gel products produced by silica gel can be cleaned by washing with water or in dishwasher
Third: long life
The chemical property of silica gel material is very stable. The product has longer life than other materials
Fourth point: soft and comfortable
Thanks to the softness of silica gel material, the cake mold products feel comfortable, extremely flexible and not deformed
Fifth: various colors
According to the needs of customers, different beautiful colors can be deployed. Therefore, there are many silica gel crafts in the market, which are very beautiful and fashionable, becoming the favorite of stars and others.
Sixth: environmental protection and non-toxic
No toxic and harmful substances are produced from raw materials entering the factory to finished products shipping
Seventh point: electrical insulation performance
Silicone rubber has a high resistivity, and its resistance value is still stable in a wide range of temperature and frequency. At the same time, silica gel has good resistance to high-voltage corona discharge and arc discharge, such as high-voltage insulator, TV high-voltage cap, electrical components and so on.
Point 8: low temperature resistance
The critical point of ordinary rubber is from - 20 ℃ to - 30 ℃. However, silicone rubber still has good elasticity when it is from - 60 ℃ to - 70 ℃. Some special formulations of silicone rubber can also withstand very low temperature, such as low temperature sealing ring, etc.
Point 9: conductivity
When the conductive filler (such as carbon black) is added, the silicone rubber has good conductive properties, such as keyboard conductive contact point, electric heating element parts, anti-static parts, shielding for high-voltage cable, medical physical therapy conductive film, etc. Mainly used for buttons, etc.
Point 10: weather resistance
Ordinary rubber degrades rapidly under the action of ozone produced by corona discharge, while silicone rubber is not affected by ozone, and its physical properties only change slightly under ultraviolet and other climatic conditions for a long time, such as sealing materials used outdoors.
Point 11: thermal conductivity
When some heat conducting fillers are added, silicone rubber has good heat conducting performance, such as heat sink, heat conducting gasket, photocopier, fax machine heat conducting roller, etc.
Point 12: radiation resistance
The radiation resistance of silicone rubber containing phenyl is greatly improved, such as electrical insulated cables, connectors for nuclear power plants, etc.
What are the characteristics and uses of silica gel products?
A. High and low temperature resistance: it can be used for a long time at 200 ℃, and still has elasticity at - 60 ℃;
B. Dielectric properties: the dielectric properties of silica gel are excellent, especially the dielectric properties at high temperature are much higher than that of organic rubber, and the dielectric strength is almost not affected by temperature in the range of 20-200 ℃.
C. Excellent weather resistance, ozone resistance and ultraviolet radiation resistance, long-term outdoor use does not crack. It is generally believed that silicone rubber can be used outdoors for more than 20 years.
D. Excellent high temperature compression permanent deformation.
E. Good processing performance, easy forming and other advantages, can be extruded by hot air vulcanization molding, die plus molding, plus extension molding and other methods to produce a variety of products.
Because silica gel products have excellent comprehensive properties and good technical and economic effects, they have played an irreplaceable role in physical therapy, shipbuilding and industrial production
The advantages of silica gel: 1. Silica gel keyboard is environmentally friendly, non-toxic, tasteless, and elastic; 2. It is wear-resistant, high temperature resistant, non deformation and other characteristics, and can be used for a long time; 3. It has smooth appearance, strong hand feeling, and is a real green environmental protection product; 4. It can be used as monochrome, bicolor, tricolor and mixed with other colors; 5. The logo on the ornament can be the combination of words, patterns or words and patterns; silica gel is very environmental friendly and cheap, which is the favorite of white-collar workers, Chaoren and leaders. Silica gel of different models is the foam silica gel tube with different gypsum content, which is reflected in the different viscosity of silica gel, the higher the gypsum content, the more viscous it is. There are signs on the bottles selling silica gel. For example, silica gel h is very thin, and the viscosity of silica gel G is generally moderate.
