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 after curing.
Biocompatibility compliant with ISO 10993-5 and USP Class VI for medical-grade applications.
Low compression set (<15% at 150 °C/72 h), ensuring long-term sealing performance in dynamic environments.
Excellent flow characteristics and rapid vulcanization suitable for high-speed injection molding of precision parts.
Medical devices: syringe plungers, respiratory masks, and implantable component housings.
Automotive sensors and electronic encapsulation requiring thermal resilience and electrical insulation.
Consumer electronics: soft-touch overmolded buttons, wearable device gaskets, and display seals.
Optical components: LED lens encapsulants and light-diffusing elements where clarity and UV stability are critical.
