High-transparency, platinum-cured liquid silicone rubber (LSR) with excellent optical clarity and low haze.
Outstanding thermal stability — maintains mechanical integrity after prolonged exposure to temperatures up to 200 °C.
Low compression set (<15% after 72 h at 150 °C), ensuring long-term sealing performance and shape recovery.
Biocompatibility compliant with ISO 10993-5 and USP Class VI, suitable for medical-grade applications.
Optimized rheology for precision injection molding of thin-walled, complex geometries with minimal flash.
Medical devices including implantable components, drug delivery seals, and surgical instrument gaskets.
Optical light guides and LED encapsulation requiring high refractive index consistency and UV stability.
Automotive sensors and connectors demanding vibration resistance, thermal cycling durability, and electrical insulation.
Consumer electronics housings and wearable device seals where skin contact safety and dimensional accuracy are critical.
