When used with a catalyst masterbatch, these materials enable the manufacturing of thermoset insulation using the silane chemical crosslinking process. 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.

Avient and IVCC created a new medium scale masterbatch production laboratory in China to support research and development into non-registered novel active ingredients for incorporation into long lasting treated nets. Avient has extensive global ability in the formulation development and manufacturing of groundbreaking material solutions to support malaria control, including a technologically advanced anti-mosquito masterbatch for use in long lasting treated nets. The novel insecticides in development are formulated tightly into the masterbatch, allowing best bio-efficiency performance with a permanent but slow release to the surface—just enough to kill any mosquito by contact.
