Pro-fax PF531 radiation resistant, high melt flow, controlled rheology polypropylene homopolymer is available in pellet form. This resin is typically used in injection molding applications and offers enhanced retention of physical properties and color after radiation sterilization.
Pro-fax PF531 resists yellowing and embrittlement after gamma radiation. However, since performance and appearance after radiation sterilization can be sensitive to design and processing choices, the users should verify performance in their application.
Our customers typically use this resin in radiation-sterilizable medical and laboratory devices.
