product brief introduction of RTV silicone rubber raw materials for mould making
RTV silicone Rubber Raw materials for mould Making is the a kind of room temperature vulcanized polymer oproducts with two parts, part A is the silicone rubber base and part B is the platinum/condensation cure hardner.
The silicone rubber manufactured by sibetter Silicone rububer factory is made by new materials, and is not granule or crust recycled from waste rubber/plastics. Also, there isn't extra powder or silicone oil or other kind of oil added to lower the production cost. quality is guaranteed.
usually, our silicone rubber is with features of:
• easy for operation
• reproduce intricate details
• resist tearing with repeated use
• provide good resistance to most chemicals
• offer variable cure times at room temperature
• flexible to reduce de-molding and stress problems
• high duplication times(e.g.800-1000times for gypsum products)

XB-715#
type: tin/condensation cure mould making silicone
brand: sibetter Silicone Rubber
main Application: XB-715# is in the hardness of about 15 shore A, then the application of XB-715# would be used to make mould of the products within 30cm with fine patterns, such as the toys, PU crafts, resin casting, candles, soap, snow tires and similar products.
XB-730#
type: tin/condensation cure mould making silicone
brand: sibetter Silicone Rubber
main Application: XB-730# is in the hardness of about 30 shore A, then the application of XB-730 would be used to make mould of the products in medium size such as 40~50cm with simple patters, such as the concrete/cement/stone products, plaster line/conics, concrete stamping, garden statues, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, poly resin crafts, polyurethane, bronze, wax and similar products.
XB-615#
name: platinum/addition cure silicone rubber
brand: Sibetter silicone rubber
main Application:XB-615# is in the lower hardness, then the application would be used to make mould of the products within 25cm with simple patterns or smaller products with fine patterns, toys, PU crafts, resin casting, candles, soap, snow tires, small concrete bricks, art works etc. And for it is the food grade silicone rubber, it can be used to make molds of the fancy candy, small cakes/chocolate, fondant decorations, sopa, candle, sugar, lace, and so on. Also, it is very popular to make silicone insoles, and sibetter can offer blue, pink, red color for this applications.
XB-640#
name: platinum/addition cure silicone rubber
brand: sibetter silicone Rubber
main Application: XB-640# is in the large hardness, then it can be used to make moulds of large products, such as the plaster window decoration, GRC/GRFC products, furniture, roman column mold making, and similar products. But the most general application of this kind of silicone rubber with large hardness and low shrinkage is for prototype design of a variety of precision parts mold making, such as aerospace parts, auto parts, military supplies, silicone robot molds, cars, ships and other accessories. they are also used for the jewel mould making.
gernal package of platinum cure silicone rubber
The mixing ratio of the platinum cure/additional silicone rubber is 1:1, so the part a and part b would be half.
gernal package of tin cure silicone rubber
The mixing ratio of tin/condensation cure silicone rubber is 100:3, thus 3% catalyst would be offered for free. And if you dont want the plastic bags in side, catalyst would be sent in extra drums.
