1. Liquid Silicone Rubber applications

Liquid Silicone Rubber 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, 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.


2. Liquid Silicone Rubber features description

Liquid Silicone Rubber 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 easy operation, non-deformation, high-temperature resistance, acid-alkali resistance and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

3. Liquid Silicone Rubber operations

If the customer wants to make large products and large size molds, the mold should be made of mold making silicone rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of mold making silicon rubber 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.

4. Liquid Silicone Rubber frequently asked questions

1). Why does the mold making silicone rubber mold have few molding times?

The mold making silicone rubber mold has few molding times is due to following reasons:

A. Adding too much silicone oil which will destroy the molecular of silicone rubber;

B. Making the mold for small and detailed patterns products with higher hardness silicone rubber which is easy to break; Making the mold for large and simple 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.
