RTV silicone rubber for candle making molds

RTV silicone rubber for candle making molds is a kind of molding silicone rubber. It can be categorized as two types, namely condensation cure RTV silicone rubber and addition cure RTV silicone rubber. With the high quality silicone rubber, it is easy to make molds for candles by hand or machine. Silicone made by Hong Ye Jie Technology must be an ideal option for you. Let’s make comparisons with the general two types of the RTV molding silicone. The condensation type molding silicone has a lower price. Its shrinkage is limited within 0.3%. Its curing rate is constant, and the rate has nothing to do with the temperature or pressure. It contains two components, of which one part is silicone liquid and the other part is tin catalyst. The dosage of the tin catalyst should be 0.2% to 0.3%. Then let’s have a look at the addition cure type molding silicone rubber. This kind of material is a little more expensive than the condensation type. Its shrinkage is limited within 0.1%. However, the curing rate of this kind of RTV silicone rubber for candle making molds is not constant, because when you heat it, its curing rate can be elevated by a large margin. During the curing phase, it will not release any byproduct at all. It also contains two components, but its two parts is different from the condensation type. We usually set the mixing ratio as 1 to1 or 10 to 1, which is very convenient for operation. What’s more, the addition cure type RTV silicone is completely food grade.   Shenzhen Hong Ye Jie technology Co. Ltd provides for you with high-class RTV silicone rubber for candle making molds.
