In order to reduce the viscosity ofsilicone rubber and pursue a good quality, you may add a lot of silicone oilinto the silicon rubber when making molds. In fact, it might have just theopposite effect. The tension and the tear strength will be reduced badly withthe addition of silicon oil. And the silicon molds will be in a weak and flimsymanner.
Whyis the tear strength of the silicone mold weak?
Frequently asked questions of molding silicone rubber
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.
Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50A
RTV silicon rubber Flexibility,easy to demould,fine production detail,high tear strength room temperature curing
