Product Description

Platinum Cure Silicone

Description

Mold Making Silicone rubber is a two-component silicone room temperature mold rubber (Room Temperature Vulcanization), referred to as RTV, commonly known as Silicone. This is a two-component compound. The A component contains a cross-linking agent, and the B component contains a catalyst. During the packaging process, the cross-linking agent and the catalyst must be separated. Its vulcanization is carried out at room temperature. As long as the two components are mixed in a certain ratio (the specific ratio can be determined according to the operating time and product performance), the two-component compound will undergo a cross-linking reaction to form a flexible and elastic colloid.

Features

1. It has the characteristics of no deformation, high temperature resistance, acid and alkali resistance, and no expansion.

2. Good shrinkage rate, many times of re-molding, mold silicone shrinkage rate is 2/‰。

3. Good tension, elasticity, and good tearing, not only make your products beautiful, but also make your products not deformed. There is no problem with high temperature resistance at 200 degrees, and the silicone mold of minus -50 degrees is still not brittle and still It is soft and the simulation effect is very good.

Application

Mold silicone is used for PU resin crafts, plaster crafts, unsaturated resin crafts, polka, crystal, candle crafts, large sculptures, cultural relic reproduction, architectural decoration, relief furniture, plastic toys, gifts, stationery, imitation marble, human statues, imitation Mold manufacturing in many industries such as copper crafts, cultural relics production, model facilities, and simulation of landscapes etc..

Note: Many industries are indispensable for quick copying of products.

Type

Mold silicone rubber can be divided into addition and condensation type.

A1: Room temperature vulcanization condensation molding silicone rubber, it has excellent fluidity, mold release, easy to operate, vulcanization time and operation time can be adjusted as needed, deep vulcanization, stable mold size, heat resistance, chemical resistance, and good physical properties , High tear strength, especially for unsaturated polyester products, good durability and long mold life.

B1: Addition molding silicone rubber, it has the characteristics of good transparency, easy deep curing and low shrinkage.

A2: Silicone rubber soft molds made of condensation mold glue are mainly used for mass production of handicrafts, furniture parts, lighting parts, and other decorative products made of unsaturated polyester, epoxy resin, polyurethane resin, gypsum and paraffin wax. . It can also be used for leather printing, transfer plastic heads and other elastic products.

B2: Addition molding silicone rubber is mainly used for the production of precision molds and exquisite replicas.
