If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the mold or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also bring about unsmoothness of the mold.

We offer mould making silicone rubber. Specifications silicon features:1) for soaps mold making.2) high tensile, tear-strength.etc.3) low shrinkage 4) non-deformation4) free catalyst sell rtv-2 mould making silicone rubber for soap molds silicon rubber for soap mold making applications silicon 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. silicon 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. silicon 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.)
