Plaster Molding Silicone Rubber

HY-625 is liquid rubber(condensation cure rtv, or tin cure silicone) mainly used for silicone plaster molds, with the advantages of good tensile strength, high tear strength, high temperature resistance, excellent chemical resistance, high duplication times, long-term stability, high durability, etc. This molding rubber is one of the products with the highest use level in the production of craftwork gifts and its shrinkage is even lower than 2‰.

PLASTER MOLDING SILICONE RUBBER APPLICATION:

The rtv mould rubber is mainly applicable to mold duplication of ornamental plaster products or plaster decorations such as plaster cornice, plaster ceilings, plaster ceiling rose, ceiling rings etc. It is also suitable for fabrication of precision molds. RTV mould rubber and silicone rubber are general called two-component room temperature vulcanization silicone with excellent fluidity and good operational flexibility, easy moulding process, and so on. Add curing agent of 2%-5% at the room temperature, the rtv mould rubber is still operational within 30-60 minutes,and after 2-5 hours, the silicone elastomer(silicone mold) will be obtained with resistance to deformation, extremely high or low temperature, acid and alkali and expansion.
