CYROLITE CG-97 compound is an impact-modified acrylic-based multipolymer for molding and extrusion of medical applications.

Typical properties of CYROLITE® acrylic-based multipolymer compounds are:

excellent chemical resistance to fats and oils

excellent bonding and welding capabilities

excellent bonding to PVC tubing

good impact strength

good light transmission

good resistance to EtO, gamma and E-beam sterilization

The special properties of CYROLITE CG-97 compound are:

superior resistance to lipids

excellent gamma sterilization color stability

high impact resistance

very good resistance to alcohol

Used for injection molding and extrusion of medical devices.
