Röhm CYROLITE® G-20 CP Acrylic polymer
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Extruded
Material Notes:	CYROLITE® G-20 CP is a PMMA-based copolymer for injection molding and extrusion of UV- Light protective medical applications. Typical properties of CYROLITE® G-20 CP are: Excellent Processability 5 times the impact resistance of unmodified acrylics Resistant to body fluids and many chemicals Excellent bonding to PVC tubing Can be thermal bonded, ultrasonic and laser welded Good heat resistance Resistance to EtO, gamma and E-beam sterilization Special Properties of CYROLITE® G-20 CP compound are: Low UV-light transmission <1.0% 260 - 480 nm Excellent Transmittance between 500 – 780 nm Application: Used for injection molding and extrusion applications that require UV-light protection in infusion therapy medical devices. CYROLITE® G-20 CP ensures integrity of photosensitive substances such as oncology drugs, antibiotic, and antifungal agents. Information provided by Roehm America LLC
