LyondellBasell, one of the world's largest plastics, chemicals and refining companies, is bringing to market the new PurellRP375R a polypropylene (PP) random copolymer that delivers excellent resistance to gamma and X-ray radiation sterilization. These sterilization methods help to minimize risk for patients by reducing microbial load on injection molded medical devices and other healthcare applications.

Polyolefin resins used in applications requiring gamma or X-ray irradiation must be correctly additivated to mitigate the effects of radiation on the polymer structure, which may cause them to turn yellow and become brittle. To address these requirements and improve packaging integrity, the new Purell RP375R has a tailor-made additivation package that delivers good impact strength and resistance to yellowing.

“The good flowability delivered by Purell RP375R will help our customers produce thin-walled and complex design items in short cycle times and at low conversion temperatures”, said Rodney Fox, marketing manager of LyondellBasell’s European PP Healthcare and Caps and Closures business. “Our team is working to innovate and explore new products that help our customers advance quality healthcare.”

Purell RP375R is produced with a non-phthalate based catalytic system and offers excellent transparency with good balance of physical and mechanical properties. As part of the Purell family of grades, this resin also benefits from LyondellBasell’s Purell Service Concept, offering dedicated manufacturing procedures and standards for products to meet customer material requirements for the pharmaceutical and healthcare industry.
