Purell HM671T

About
Without exception, all potential activities for applications in the pharmaceutical, medical device, laboratory and diagnostics area have to be discussed with the relevant Technical (P & AD) and Business contacts first. To discuss a medical/pharmaceutical application please contact: your local Distributor or your local Basell contact. Purell HM671T is a high fluidity metallocene-catalysed polypropylene. It is nucleated and has a gamma – ray stabilizing additivation. Purell HM671T is a medical grade designed for injection moulding applications in medical after approval is given by Basell. Purell HM671T exhibits a very high stiffness combined with an excellent transparency and out-standing organoleptic properties. Its very narrow molecular weight distribution makes it particularly suitable for distortion-free mouldings. Purell HM671T is applied in high transparency and rigid pharmaceutical and diagnostic applications such as well and microtitre plates, measuring cups and labware.&&
