PP high crystallinity
Purell EA678P
Natural
Description
Purell EA678P is a nucleated polypropylene impact copolymer delivering an exceptional combination of stiffness and toughness, with a tensile modulus of 1750 MPa, Charpy notched impact of 6.5 kJ/m² at 23 °C (3.0 kJ/m² at 0 °C), and an MFR of 18 g/10 min. Developed for the healthcare sector, Purell EA678P targets injection molded medical device components where high mechanical performance and chemical resistance are essential. The grade maintains 50% tensile strain at break, providing the ductility needed for durable medical parts.
Processing Techniques
Injection molding is the recommended process for Purell EA678P, where the 18 g/10 min MFR ensures efficient cavity filling of precision medical components. The nucleated formulation of Purell EA678P accelerates crystallization for consistent part quality and improved cycle times in high-volume medical device production. Purell EA678P benefits from tightly controlled processing parameters to achieve the dimensional accuracy and surface finish standards required in healthcare applications.
