Molding Silicone Rubber

Applications of molding silicone rubber
Molding silicone rubber is suitable for industries such as toys, gifts, decoration, plate engrave, human replica, art crafts, resin crafts, poly resin crafts, unsaturated resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist statue crafts.

Working techniques for molding silicone rubber
According to the different materials, we can supply two series of molding silicone rubber, which are HY-6 and HY-7.

(1) HY-6 Series includes model codes of HY-620, HY-640, HY-628, HY-638 with the hardness of 18-22 shore A, 38-42 shore A, 25-30 shore A and 35-40 shore A respectively.

HY-620 and HY-640 series molding silicone rubbers are particularly suitable for pouring mould.

HY-620 is for small crafts mould making, while HY-640 is for large crafts mould making. Common features of HY-620 and HY-640 are light viscosity, pourable effort, good fluidity, easy-operation, high tensile and high tearing strength.

HY-628 and HY-638 are particularly suitable for brushing mould making.
Common features of HY-628 and HY-638 are moderate viscosity, easy-operation. Agents are available if requested. It won't affect the quality of mould making silicone rubber but to make the operation much easier.

(2) HY-7 Series includes model codes of HY-718, HY-728, HY-738 with the hardness of 15-20 shore A, 25-30 shore A and 35-38 shore A respectively.

HY-718 is a kind of soft silicone rubber and suitable for pouring mould making of small crafts.
HY7-28 with moderate viscosity is suitable for pouring mould and collapsible mould making of crafts in medium size.
HY-738 with high hardness is suitable for to collapsible mould making of crafts in large size.

Features of molding silicone rubber
1. Good characteristics of easy-operation
2. Light viscosity and good flowability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. Favorable hardness
7. High temperature resistance, acid and alkali-resistance and ageing resistance

Limitations of molding silicone rubber
1. When the hardness of mold making silicone rubber is lower than 15 shore A, the tension, the tear strength, the ageing resistance, acid and alkali-resistance of silicone rubber will reduce respectively.
2. When the hardness of silicone rubber is higher than 50 shore A, the tension and the tear strength of silicone rubber will reduce, and the solidified silicon mold will be easily broken.
