Development: American Clariant Masterbatches
Characteristics: This new type of additive is the reactive additive CESA-Extend. This product enables the long-chain branching of PET molecules to increase the intrinsic viscosity of recycled PET without reactor solid-phase reaction. Its other role and advantage is to improve the compatibility of recycled PET with other polyesters, polycarbonates, and nylons.
Uses: CESA-Extend can undergo polycondensation reaction with polycarbonate, nylon, polyoxymethylene, thermoplastic polyurethane, PET and the above polymer blends, but it is most effective for PET, and it is the worst for nylon and can react with it. The groups include amide groups, isocyanate groups, carboxylate groups, and hydroxyl groups.
