IV variability ColorMatrix™ rePrize™ IV Builder for PET Chain extender to repair PET chains, increasing the melt and intrinsic viscosity of rPET Reacts via melt extrusion and increases viscosity in the melt phase.

This technology offers manufacturing efficiencies versus other crosslinking methods: • Reduction in logistics management: No secondary steps after manufacturing; no need for E-beam radiation for effective crosslinking • Rapid ambient curing: Typically in less than 15 days depending on the climatic condition, wall thickness and catalyst level • No additional capital investment: The material can be processed on a conventional extrusion line • Easy handling: ECCOH XL 8001 is used with 2.5–5% of catalyst masterbatch • No pre-drying: No need to pre-dry the material if it is stored correctly PRODUCT BULLETIN KEY CHARACTERISTICS Avient’s ECCOH line of highly flame retardant, non-halogenated materials limits the emission of corrosive gases when burning.
