antioxidant leadaox p-epq, cas no.119345-01-6

description

trade name: leadaox p-epq phosphite ester antioxidant.
chemical formula: c68h92o4p2.
chemical name: tetrakis(2,4-di-tert-butylphenyl)-4,4’-biphenyldiphosphonite.
synonyms: pepq; p-epq.
cas no.:119345-01-6. formula weight: 1035.4g/mol.
highly efficient phosphorus based secondary antioxidant.
leadaox p-epq, a highly efficient phosphorus based secondary antioxidant, can reduce the thermo-oxidative degradation of polymers and the development of undesired coloring (yellow) during processing. main advantages of leadaox p-epq are its high thermal stability and broad compatibility in coating polymers.
highly effective processing stabilizer for thermoplastic polymers, especially for polyolefins but also engineering plastics, among them, polycarbonates, polyamides, polyesters. the product stabilizes the polymer melt in a unique manner against thermo-oxidative degradation ensuring constant melt viscosity as well as outstanding color stability, even under the highest thermo-mechanical stress.
based on its chemical composition, p-epq exhibits optimal compatibility with most polymers, so that no migration or chalking problems occur.

potential applications

leadaox p-epq has a wide scope of applications in thermoplastic polymers, particularly suitable for pc, pet, pa, pbt, ps, pp, pe-lld and eva substrates etc.
it is preferably used for the stabilization of polyolefins, primarily in combination with phenolic antioxidants such as antioxidant 1010, with which it forms synergistic systems.

particularly in polyolefins, produced with newer-generation catalysts, the product is outstandingly effective.
filled polyolefins, e. g. talc-filled polypropylene
polyethylene of low density, e. g. vldpe, uldpe
polyethylene of high density (hdpe)
poly-4-methylpentene-1 (tpx)
polybutene-1
polycarbonate
polystyrene, incl. hips, abs, san
thermoplastic polyester
reprocessed recycled plastics

handling & safety

leadaox p-epq should be handled with care to prevent contamination of the environment. avoid dust formation and ignition sources. for more detailed information please refer to the material safety data sheet.

transportation

leadaox p-epq is not dangerous materials according to the transportation regulations.
