The features of silicone rubber
silicone rubber for mold making is a kind elastic silicon rubber mold which features as below:
- resistance to deformation,
- high-temperature resistance
- acid-alkali resistance
- expansion as well as high reproduction times,
- good tensile strength ,
- Strong Tear strength
- Good elongation
- Low shrinkage
- Long shelf time which can reach at least 1 years
silicone rubber operations
During operate the three impotant thing to pay attention :
1. weigh theliquid silicone rubber and curing agent exatly .
2. Stir theliquid silcone rubber and curing agent evenly .
3.we shouldchoose the right hardness to making diffirent size of product mold.
