Name:hy-638 mould silicone rubber Number: Hy-638 Usage: For toy gifts and craftwork gift, products with complex fine details, and made in pouring way. Description: ííííhy-638# silicon rubber is mainly used for toy gifts and craftwork gifts 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 2íd. Applications: íííípoly technique, lightings, candles, and molds in multiple pieces for large products.

Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles, etc. And fabrication of precision molds. 25kg/drum 200kg/drum
