PP random copolymer
Purell RP373R
Natural
Description
Purell RP373R is a clarified polypropylene random copolymer with a slip agent, featuring an MFR of 25 g/10 min, a tensile modulus of 1000 MPa, and a Charpy notched impact of 6.0 kJ/m² at 23 °C. Specifically designed for disposable two-part syringes, Purell RP373R provides the transparency needed for visual fill-level verification and the slip performance required for smooth plunger action. With retained impact strength of 2.5 kJ/m² at 0 °C and elongation at break exceeding 50%, this grade ensures reliable mechanical performance across storage and use conditions.
Processing Techniques
Injection molding is the designated process for Purell RP373R, where the 25 g/10 min MFR enables precise filling of syringe barrel molds with the tight tolerances that medical device manufacturing demands. The slip agent in Purell RP373R contributes to consistent plunger glide force in two-part syringe assemblies, a critical functional requirement for healthcare end users. Uniform melt temperature and consistent cycle parameters are essential to achieve the optical clarity and dimensional precision this medical-grade material is designed to deliver.
