Silicon rubber for mould making features

Silicon rubber for mold making is flowing liquid with general hardness of 22-50 A° after curing with features:

1. resistance to deformation and high-temperature, acid-alkali and expansion

2. good tensile strength, tear strength and elongation

3. high reproduction times

Silicon rubber for mould 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. Our curing agent is free charged.

(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 Silicon rubber for mould making

Why does the Silicon rubber for mould making just has few duplication times?

The silicon rubber mold just has few duplication 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.
