HY-638#MOLDING SILICONE FOR STONE
HY-638# molding silicon is particularly suitable for artificial stone ,gypsum/plaster ,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 large products or fine and precision products which is difficult to demould. This molding silicon is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 2‰.
Strong Tear Strength Liquid Silicone Moulds (liquid silicone rubber) for operations
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
