Usually,the resin will release a lot of heat when pouring into the silicone molds,which will cause the burnt of silicone molds ,lead to a short life of the silicone molds.So we suggest customers to use high hardness (HY638) silicone.HY638 is the best choice for you.Of course ,if the temperature of resin released is not over 60C,then we could recommend customer product according to the features of the resin products.High hardness for large size resin products,while low hardness for small size.
