addition silicone rubber

Main features of addition silicon rubber
Low Viscosity, good operability, exceptional fluidity,good temperature, solvent resistance, and insulation properties, excellent tensile and tear strength, as well as good

elasticity.
 
Applications of addition silicone rubber
It mainly use for making precision molds, silicon insoles, food grade molds(chocolate, cake moulds) life casting silicon products, fabric finishing, seal for electronic

components and solar circuit board, trademark decoration, baby nipples, cable accessories, etc.

Using Instructions of addition silicone rubber
1.       Applicable to the injection molding process
 
2.     Mixing component A with B evenly according its mix ratio, it is ready for use after degassing , it cures by heating up the temperature when pouring into the mold.
 
 
3.     The curing time is subject to the temperature, short time will be required under high temperature, long time will be required while the product with large thickness.
 
Package and storage precautions about addition silicone rubber
1.       The material is packed in 20kg per drum.
 
2.     It is non-dangerous goods, should be stored at a cool and dry place, keep from sun and rain.
 
3.     The service life is 12 months, it can be used after reinspection when exceeding time limits.
 
It is forbidden to mix with organic compounds of condensation cure silicone rubber, otherwise, the silicone rubber will not cure or vulcanize. It also should keep from organic

compounds containing S,P,N, and metal salt of organic acid which causing silicon not cure or unvulcanized.
