HCR silicone rubber is a silicone elastomer shaped of straight chains with exceptionally high sub-atomic weight. The framework will be restored with either a natural peroxide crosslinker, or a platinum impetus. HCR offers incredible temperature and maturing opposition.


Substance structure


HCR silicone rubber elastomers are otherwise called HTV. They are produced using responsive silicone gums, at the end of the day, in a row chains, with extremely high sub-atomic weight macromolecules containing different receptive gatherings. The most as often as possible utilized gums are either somewhat phenylated or perfluorinated vinylated gums. Different crude materials are added to give extra properties to the HCR for example smoldered or encouraged silicas with high explicit surface region to improve mechanical properties, heat stabilizers and different added substances, for example, plasticizers or hostile to organizing specialists. Cross-interfacing happens using normal peroxides in polycondensation systems or platinum impulses in polyaddition structures.


HCR silicone properties


HCR silicone rubber elastomers have exceptional properties and are far better than customary natural elastomers. They display extraordinary mechanical strength at temperature and can be utilized at temperatures going from - 50°C to +300°C. The maturing opposition of these elastomers features their essential characteristics, for example, the way that they are artificially inactive, their photograph oxidative steadiness and the shortfall of leftover responsive gatherings once relieved. An abundance of colorings are conceivable. By utilizing an adequately fine silica filler it is even conceivable to make straightforward articles for use in food and paramedical applications. The development of various added substances opens boundless for customization of HCRs to make answers for all kind of existing and new applications in Aerospace, Automotive, Healthcare, Oil and Gas, Construction, Electronics. Latest models are heat move added substances for Electrical Vehicles, electrical conductive materials for Power or Consumer Electronics and furthermore antibacterial answers for Healthcare applications.


Why use HCR silicones?


We should take the case of electric vehicle to comprehend the advantages of HCR silicone rubber. As we have seen over the innovation display protection from high and low temperatures and they offer adaptability for added properties. Auto link makers have consequently been utilizing silicone rubber HCR rather than different polymers (like TPU/TPE and XLPE) to guarantee longer maturing time under high temperatures and simple introduce in the inexorably more modest spaces found in more current age autos. Links made with HCR can coordinate with the requirements produced by steady development in the Electric Vehicle industry, particularly for the association between the motor and the battery.


Related applications


HCR silicone rubbers remarkable properties are utilized in various modern applications: fixing and channeling in liquid hardware (joints for building development and aeronautical applications, car gaskets, boots and hoses), electrical insurance (office gear security links and protectors for electrotechnical applications, sparkle plug boots, links and connectors for auto application), food, drug and biomedical applications (tubes, profiled areas).
