CYROLITE CG-97 Lipid Resistant Medical Acrylic Copolymer
Material: PMMA-based Copolymer
Impact: 143 J/m
Lipid Resistance: Superior
Medical: USP Class VI
Packing: 1500 lb boxes
CYROLITE CG-97 offers superior lipid resistance combined with the highest impact strength (143 J/m) in the CYROLITE family and excellent gamma sterilization color stability.
CYROLITE CG-97 is a lipid resistant, medical grade PMMA-based copolymer designed for medical device applications requiring superior lipid resistance and gamma sterilization stability. With a notched Izod impact strength of 143 J/m at 23°C — the highest in the CYROLITE family — this material delivers exceptional durability for demanding medical applications. Its superior lipid resistance ensures reliable performance in contact with fatty substances, making it ideal for IV filtration and pediatric medical devices.
CYROLITE CG-97 offers excellent gamma sterilization color stability, maintaining its optical clarity and appearance after gamma radiation exposure. It provides 87% light transmission with 5.0% haze (3.2mm), ensuring good visibility of fluid pathways. The material meets USP Class VI (colorless) and ISO 10993-1 biocompatibility requirements, and offers resistance to body fluids and many chemicals. It is processable on standard injection molding and extrusion equipment with 3-zone general purpose screws. Typical applications include needle hubs, IV filters, lab filters, and pediatric filters where lipid resistance, gamma stability, and high impact resistance are critical.
