Mold making silicone

Mold making silicone applications Mold making silicone rubber use in mold making field for manufacturers of of products made of unsaturated resin, epoxy resin, polyurethane, etc. toy gifts and craftwork gifts, poly technique, lightings, candles, and molds in multiple pieces.
Mold making silicone features mold making silicone rubber with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is 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 is up to 2.Mold making silicone datasheet
