        SILICONE RUBBER FOR MOLD MAKING APPLICATIONS:
        Silicone rubber for molding making is primarily intended for poly resin crafts,PU crafts,PU resin crafts ,gypsum crafts ,

        unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry, a large statue Buddha,

        relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-

        scale cement mold, artificial fossils Factory,Europe component factory, simulation landscapes, animals and plants

        sculpture, sandstone crafts and so on.


        SILICONE RUBBER FOR MOLD MAKING FEATURES:
        Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50A°after curing. Molding

        silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature,

        acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation.

        For small products mold making, we advise you make in pouring way.


        SILICONE RUBBER FOR MOLD MAKING 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.)

         

        Frequently asked questions of moulding silicone rubber
        Why does the silicone rubber mold have few molding times?
        The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will

        destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness

        silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce

        the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone

        rubber to make the mold for suitable products.
