General Purpose Silicone Custom Hcr Raw Materials Solid Silicone Rubber for O-Ring Gasket Sealing

Product Description

What is HCR 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.



Properties

Heat Cured Rubber elastomers have outstanding properties and are far superior to conventional organic elastomers. They exhibit

exceptional mechanical strength at temperature and can be used at temperatures ranging from -50°C to 300°C. The aging resistance

of these elastomers highlights their fundamental qualities such as the fact that they are chemically inert, their photo-oxidative

stability and the absence of residual reactive groups once cured.



Related applications

HCRs outstanding properties are used in many different industrial applications: sealing and piping in fluid circuitry joints for

building construction and aeronautical applications, automotive gaskets, boots and hoses, electrical protection office equipment

safety cables and insulators for electrotechnical applications, spark plug boots, cables and connectors for automotive

application, food, pharmaceutical and biomedical applications tubes, profiled sections.

The addition of various additives opens unlimited for customization of HCRs to create solutions to all kind of existing and new

applications in Aerospace, Automotive, Healthcare, Oil Gas, Construction, Electronics. Most recent examples are heat transfer

additives for Electrical Vehicles, electrical conductive materials for Power or Consumer Electronics and also antibacterial

solutions for Healthcare applications.
