Medical liquid silicone properties

First, medical liquid silicone use
Medical liquid silicone is also commonly referred to as two-component room temperature vulcanization plus shaped silica gel. The components A and B of the silica gel are all liquids, wherein the component B contains a platinum catalyst catalyst or other auxiliary agent, and the two components are mixed and cured at room temperature or under heating. Can be used in the following areas:

1. Metal mold, alloy car and other precision mold manufacturing;

2. Molding of epoxy resin, polyester resin, polystyrene, vinyl plastic, paraffin, etc.;

3. Mold manufacturing of large pieces of cement components, cultural stone, concrete, precision parts, FRP products, etc.;

4. Design and production of high-precision hand model, rapid prototyping design.

5, the production of dental molds, medical products, silicone wax, silicone dolls, silicone products, silicone parts, silicone seals, silicone tablets and other silicone products and mold production.

Second, the characteristics of medical liquid silicone

1. It can be deep vulcanized without being limited by the thickness of the product;

2, the shrinkage rate is less than one thousandth, the low molecular weight is not released during the cross-linking process, and the copied product has high precision;

3, has excellent chemical resistance, high temperature resistance, can reach 300 ° C;

4, food grade, non-toxic and tasteless, passed FDA food certification;

5, high tensile and high tear resistance, many times of mold overturning, not easy to deform;

6, good fluidity, easy to infuse, both room temperature curing can also be heated and cured, easy to operate.
