China China manufacture of molding silicone

molding silicone rubber series mold rubbers are two-component, condensation-cure, tin-catalyzed, very high tear strength, flexible mold compounds. A tough, knotty tear strength making them especially valuable to the mold making industry.
molding silicone rubber are recommended for evaluation as mold materials for polyester, epoxy and polyurethane resins, as well as for waxes and many other materials.

Features of molding silicone rubber:

Room temperature cured
Easy release properties
Very high tear strength
Good chemical resistance
Low shrinkage
100:2 mix ratio
Range of hardness 20A to 40A

Operations and instructions of molding silicone rubber

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Step Two: vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available

Step Three: Perfusion Molding of gifts mold making of silicone rubber
The perfusion molding is an easy way to make molds, it’s Slowly and evenly perfuse the mixed silicon rubber into the square frame. After the cross linking reaction.

Storage and Precautions of molding silicone rubber:

molding silicone rubberfor making art crafts, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
