PP random copolymer
Purell RP375R
Natural
Description
Purell RP375R is a clarified polypropylene random copolymer with a tailored additivation package for gamma-ray sterilization resistance, offering an MFR of 25 g/10 min, a tensile modulus of 1100 MPa, and a Charpy notched impact of 6.0 kJ/m² at 23 °C. Developed for medical devices and syringes that require irradiation sterilization, Purell RP375R maintains its transparency and mechanical properties after gamma exposure. The excellent physical-mechanical balance with elongation at break exceeding 50% makes this grade a dependable choice for healthcare applications demanding post-sterilization performance.
Processing Techniques
Injection molding is the recommended process for Purell RP375R, where the 25 g/10 min MFR ensures efficient filling of precision medical molds. The gamma-stabilized formulation of Purell RP375R allows converters to sterilize finished devices without the yellowing or embrittlement that standard PP grades can exhibit after irradiation. Processing parameters should be set to maximize clarity and crystallinity, as these factors influence how well the material retains its optical and mechanical properties through the sterilization cycle.
