MFR: 6.5 g/10min
Packing: 1500 lb boxes
CYROLITE GS-90 delivers 89% light transmission with only 3.0% haze — the clearest in the CYROLITE G-20 series — combined with superior gamma sterilization color stability.
CYROLITE GS-90 is a high clarity, medical grade PMMA-based impact modified copolymer designed for medical device applications requiring superior optical clarity and gamma sterilization stability. With 89% light transmission and haze of only 3.0% (3.2mm), this material offers the clearest visibility in the CYROLITE G-20 series, ensuring excellent visual inspection of fluid pathways. Combined with 5 times the impact resistance of unmodified acrylics and a melt flow rate of 6.5 g/10min, GS-90 delivers an optimal balance of clarity, toughness, and processability.
CYROLITE GS-90 offers superior gamma sterilization color stability, maintaining its optical clarity and appearance after gamma radiation exposure. It meets USP Class VI (colorless) and ISO 10993-1 biocompatibility requirements, making it suitable for patient-contact medical devices. The material provides excellent resistance to body fluids and many chemicals, with outstanding bonding to PVC tubing and compatibility with thermal bonding, ultrasonic welding, and laser welding. Typical applications include Y-sites, luer locks, needle hubs, connectors, check valves, and drip chambers where clarity, impact resistance, and gamma stability are critical.
