Feature of Tin Cure Silicone Rubber
1. Strong tear resistance, high and low temperature resistance, acid and alkali resistance, and aging resistance;
2. Good fluidity, easy to release foam, easy to demould, and the finished product will not turn white;
3. The silicone mold can be turned over frequently and has a long service life;
4. The linear shrinkage rate is less than two thousandths;
5. Product color, hardness, viscosity, and operating time can be adjusted as needed.
Advantages of Tin-Cure Silicone Rubber
Tear-resistant and long-lasting
Compared with others, Hannast molding silicone has better flexibility and stronger tear resistance, and the silicone mold has a longer service life and can be reused many times.
Low shrinkage and precise reproduction
The shrinkage rate is negligible, ≤2‰, enabling the reproduction of the finest and most complex details.
Non-Toxic & No Odor
Made of premium silicone material, liquid silicone rubber will not produce unpleasant odors, allowing you to use more assured
Good Fluidity
Liquid silicone rubber has good fluidity, self-leveling, easy-release bubbles,and easy pouring to help complete the mold.
