Speciality Chemicals These are clear, mobile liquids and are mainly used as chelators in liquid PVC stabilizers. These pure compounds improve colour retention during processing of polycarbonates, polyester and polyphenylene oxide. They are also used as stabilizers in ABS, Polyurethane, Coatings and PET systems.
Stabilizer used in epoxies, as component in PVC stabilizer mixtures for heat and light stability, in PP, HDPE, LDPE and ABS.
