The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine
detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength
of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
Why does the silicone rubber mold have few molding times?

Silicone rubber (HY-638 RTV-2) instruction:
Tear Strength (kgf/)
Tensile Strength (kgf/c)
Silicone rubber HY-638 application:
Silicone RTV (HY-638 ) is two parts condensation liquid silicone rubber that can be cure under room temperature. silicone rubber mainly used for the manufacturer of products
made of unsaturated resin, epoxy resin, polyurethane, etc.
Silicone rubber(HY-638) features:
HY-638# silicone rubber is mainly with the advantages of good tensile strength, high tear strength, high temperature resistance, high
duplication times and repeated use, etc.
Silicone rubber(HY-638) is the most suitable for small products or fine and precision products which is difficult to demould. This silicone rubber is one of the products with
the highest use level in the production of craftwork gifts and the shrinkage less than 0.2%.
