What is plaster molding silicone?

Plaster molding silicone is mainly used for plaster products molds with the advantages of high tear strength, high durability, high temperature resistance, long shelf life, high duplication times etc. It is suitable for small products or fine and precision products which is difficult to demould. This plaster molding silicone is one of the products with the highest use level in the production of many kinds of products, and the shrinkage is even lower than 2‰.The rtv mold making silicone rubber(condensation curing) is generally called two-component room temperature vulcanization type with excellent fluidity and operational performance. Add curing agent of 2%-3% at room temperature, the plaster molding silicone is still operational within 30 minutes,and in 2-5 hours, a high tear silicone elastomers will be obtained with resistance to deformation, high-temperature, acid and alkali, and expansion. 　　Applications: 　　This high tear strentgh silicone rubber can be used in making molds for plaster, polyurethane , lighting ornaments, model design, stationery gifts, artifacts replia, PU crafts, and so on. 　　Operation Instruction: 　　Our product, a flowing liquid with general hardness of 34-38A°after curing process, is in white color. also you can add some dye according to your needs, but you should contact with us first, because some type of dye will affect the silicone property and quality. If  customer wants to make large products and large size molds, the mold should be made of silicone rubber with high hardness. On the contrary, if  the mold with fine and precision patterns , it should be made of silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If requires faster drying rate, more curing agent should be needed; contrarily, if requires slower drying, less curing agent is needed. If all the operation is correct, you will obtain a perfect silicone elastomers for molding. The operation is not difficult, our salesmen can give tailored molding scheme for customers.(every salesmen of Hong ye company is well trained to provide with related technical consultation) 　　Shenzhen Hongye Jie Silicone factory is specialized in silicone products and their production, research and development, and sales of Science and Technology Corporation.
