What is HVR silicone?

Heat Cured Rubber is a silicone elastomer formed of straight chains with very high molecular weight. The system will be cured with either an organic peroxide crosslinker, or a platinum catalyst. HCR offers great temperature and aging resistance.

Advantage

1.High green strength and tensile strength.
2. Heat stability in continuous use from - 50 to 200°C (can be increased up to 250°C and even up to 300°C using specific additives).
3. Exceptional ageing resistance (even under extreme conditions).
4. Great flexibility of use , wide possibilities for blending with other GT series HCR
5. Easy pigmentation using GT Silicones Color Master Batches for HCR
6. Easily extended with silica fillers (quartz type)
7. A wide range of processing and performance enhancing additives are available (plasticity adjustment, fire resistance improvement, ash cohesion improvement, … )
8. Easy to process; no sticky to rolls; easy to demold

Chemical structure

Heat Cured Rubber elastomers are also known as High Temperature Vulcanizing silicone rubber (HTV). They are made from reactive silicone gums, in other words, straight chains, with very high molecular weight macromolecules containing various reactive groups. The most frequently used gums are either partly phenylated or perfluorinated vinylated gums. Various raw materials are added to give additional properties to the HCR e.g. fumed or precipitated silicas with high specific surface area to improve mechanical properties, heat stabilizers and various other additives such as plasticizers or anti-structuring agents. Cross-linking occurs using organic peroxides in polycondensation systems or platinum catalysts in polyaddition systems.
