Product Description
Description
Artificial stone mold silicone rubber is used to duplicated for artificial stone. Generally speaking, its hardness is slightly higher, the suitable hardness is 30 to 40 shore A, which is fit for condensation cure and addition cure silicone rubber. The cost of condensation cure silicone rubber is cheaper. Due to addition cure silicone rubber is food-grade silicone rubber with non-toxic, tasteless and environmental, the price is slightly higher, each takes what you need.
Artificial stone mold silicone rubber is also a kind of ordinary liquid bi-component silicone rubber, part A is liquid silicone rubber, part B is curing agent, according to mixing ratio to mix part A and part B, then you will get the finished products.
The higher hardness of silicone rubber, the hardness of silicone mould will be higher, when it is used for cement,the mould will not be easy to deform with have high tear strength and good flexibility. Therefore, mold silicone rubber is the best material to duplicate cement products.
Features
1. High tensile and tear strength,non-deformation,suitable for artificial stone.
2. Good flexibility, easy demoulding, the product will not be damaging when demoulding.
3. Flow-ability is easy to debug:pouring with low viscosity,good fluidity and easy to release bubbles.brushing easily with adjustable viscosity.
4. High and low temperature resistance, acid and alkali resistance, non-expansion, in favor of repeated using mould.
5. Lower shrinkage on the market,have better contractility after adding fiberglass cloth.
Application
Artificial stone mold silicone rubber is specially intended for furniture architectural decoration of big stone, gypsum, cement, artificial stone, roman column, stone carving, and so on. It is also suitable for crafts and ornaments of simulated animal and plant sculpture, resin, plaster, polyester, buddhist statue etc..
