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.)

Frequently asked questions of moulding silicone rubber
Why does the mold made of silicone rubber ?have an unsmooth surface with tracks and strips on it?
It is due to?product or model to be molded should?hasn't been sanded?or polished . 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.
