Why could the silicone mold can only used for several times?
1. Adding too much silicone oil into the silicone rubber. Silicone oil is an additive which destroies the molecular weight of
silicone rubber and reduce the rension and tear strength.
2.Using the silicone rubber with a high hardness to make molds for small sized products with delicate and intricate designs
and the silicone rubber with a low hardness to makes molds for large sized products with simple designs.
