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

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