good quality RTV molding silicone rubber  description

Concrete craftworks molding silicon 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 resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

If the customer wants to make large concrete craftworks products and large size molds, the mold should be made of molding silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of molding 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 demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.

(Note: our company does not recommend you to add silicone oil. If a special soft siliconmold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)

Frequently asked questions of good quality RTV molding silicone rubber

Why does the silicon rubber mold have few molding times?

The siliconen rubber mold has few molding times is due to follwoing reasons: adding too much silicon oil which will destroy the molecular of molding siliconrubber; making the mold for small and fine detailed products with higher hardness molding siliconrubber which is easy to break; making the mold for large products with soft molding silicon 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.
