Huntsman developed new random copolymer grades using the Rexene process and fourth-generation ZN catalysts. Retexe 13M11A has a PP MFR of 1g/(10min) for pharmaceutical and electronics packaging, with a flexural modulus of 1033.5MPa and an Izod notched impact strength of 53.4J/m. Brands 23M2A, 23M2ACSl98 and 23M2ACS038 are injection molded and extruded. And stretch blown resin, MFR are 2g/(10min), bending modulus 1033.5MPa, with different additives for packaging special drugs. These resins have improved rigidity, color stability and heat resistance and are autoclavable.
