PP random copolymer
Purell RP374R
Natural
Description
Purell RP374R is a clarified polypropylene random copolymer with an MFR of 25 g/10 min, a tensile modulus of 1000 MPa, and a Charpy notched impact strength of 6.0 kJ/m² at 23 °C, specifically engineered for disposable three-part syringes and medical devices. The clarified formulation of Purell RP374R provides the transparency healthcare professionals need for accurate visual dose verification. With elongation at break exceeding 50% and consistent impact retention at 0 °C, this grade ensures structural reliability throughout the medical supply chain.
Processing Techniques
Injection molding is the primary process for Purell RP374R, where the 25 g/10 min MFR delivers the flow characteristics needed for precise three-part syringe barrel production with consistent wall thickness. Purell RP374R requires tight processing parameter control, particularly melt temperature and injection speed, to achieve the transparency and dimensional accuracy critical for medical device certification. Mold temperature and cooling time should be optimized to maintain the clarity and mechanical performance of finished syringe components.
