Thermosets
Silicone HTV for Molding — High Temperature Vulcanizing Silicone Rubber
HTV silicones are processed by kneading and then vulcanized (cured) at elevated temperatures, often with peroxides or platinum catalysts. They offer excellent mechanical properties and thermal stability, suitable for producing durable, flexible parts.
