Doverphos® LGP-12

Doverphos® LGP-12 by Dover Chemical (ICC Industries) is a unique, innovative, proprietary liquid polymeric phosphite stabilizer. It is derived from bio-sourced raw materials and acts as an alkylphenol-free antioxidant. It is compatible with thermoplastic resins, effectively reducing additive migration. It scavenges free radicals generated during the thermal degradation of polymers, preventing gel formation and other degradation byproducts. The best time to introduce LGP-12 is during PCR re-granulation, as otherwise the material undergoes heat cycles without stabilization, resulting in more pronounced gels. It can be used in LLDPE, HDPE, PP and other polymers to protect against the effects of oxidative and thermal degradation to maintain MFI, smooth processing and low color. Doverphos® LGP-12 is effective as a replacement for TNPP, post-consumer resin (PCR) and post-industrial resin (PIT). It finds application in formulating films. It can be used at lower loading levels due to its superior performance, low volatility and high phosphorus content.
