High-transparency, platinum-cured liquid silicone rubber (LSR) with excellent optical clarity and UV stability.
Low viscosity before curing enables precise metering, efficient mold filling, and compatibility with high-speed automated injection molding systems.
Excellent biocompatibility, certified to ISO 10993-5 and USP Class VI for medical-grade applications.
Outstanding thermal stability — maintains mechanical integrity from −40 °C to +200 °C after vulcanization.
Minimal extractables and low compression set, ensuring long-term sealing performance in demanding environments.
Medical tubing and catheter components requiring clarity, flexibility, and sterilization resistance.
Optical light guides and LED encapsulation where high refractive index and minimal yellowing are critical.
Pharmaceutical stoppers and seals for vials and syringes compliant with regulatory requirements.
Wearable health sensors and skin-contact devices demanding soft touch and hypoallergenic properties.
Microfluidic device components requiring fine feature replication and chemical inertness.
