Concrete Silicone

Concrete silicone is also known as concrete molding silicone and stone molding silicone. It is used for the production of silicone moulds for various artificial cement cultural stones, cement art stones, cement relief backdrops, walls, artificial rock stones, floor tile, bricks block-outs etc. and other cement plaster product series. The finished silicone rubber molds has good resistance to heat, deformation, acid and alkali, and expansion, and is useful in the replication process of every detail of the model design.
