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.
