Product Description

Name:HY-638 Mould Silicone Rubber

Number:HY-638

Usage:For toy gifts and craftwork gift, products with complex fine details, and made in pouring way.
Description:HY-638# silicon rubber is mainly used for toy gifts and craftwork gifts with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is suitable for small products or fine and precision products which is difficult to demould. This silicone rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 0.2%.

Applications:Poly technique, lightings, candles, and molds in multiple pieces for large products.

Standard Datasheet:

Model	Appearance	Viscosity (cs)	Hardness (Ao)	Tensile Strength (kgf/CM2)	Tear Strength (kgf/CM)	Elongation (%)	Mixing ratio(%)	Operating Time(H)	Curing Time(H)
638	White	14000~16000	25~28	≥35	≥25	≥500	2~3	0.5	2~4

General Description:RTV-2 molding silicon rubber and silicone rubber are general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes,and in 2-3 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles, etc. and fabrication of precision molds.
