1. Description of Tin Cure Silicone mold making rubber
Tin Cure silicone also called condensation-cure silicone, these are high-tear silicone rubbers that are known as the “work horse” of the industry because of their performance and economy.It curing by poly condensation process.The ratio is usually 100:5 in weight, demoulding time can change from 3 to 24 h according to the type of catalyst used.
2. Features of Tin Cure Silicone mold making rubber
Good chemical resistance to aggressive components that the resins contain
Good resistance to tearing
Reproduction accuracy even of micro-details
Dimensional stability in time ( deformation - shrinking only up to 0.3 % )
Remarkable resistance to high temperatures (up to 200 - 220℃ )
Final curing at room temperature
3. Applications of Tin Cure Silicone mold making rubber
