High-transparency, platinum-cured liquid silicone rubber (LSR) with excellent optical clarity and low haze.
Outstanding thermal stability — maintains mechanical integrity from –50 °C to +200 °C long-term.
Low compression set (<15% after 70 h at 150 °C), ensuring reliable sealing performance in dynamic applications.
Biocompatibility compliant with ISO 10993-5 and USP Class VI for medical-grade use.
Excellent flow characteristics and rapid cure profile suitable for high-precision injection molding of thin-walled parts.
Medical devices: disposable syringe plungers, respiratory masks, and drug delivery component seals.
Optical components: light guides, LED encapsulants, and transparent sensor housings requiring UV stability.
Automotive: turbocharger hose gaskets, EV battery module seals, and under-hood sensor boots.
Consumer electronics: waterproof membrane switches, wearable device gaskets, and camera lens barriers.
