Doverphos® LGP-12

by Dover Chemical (ICC Industries)

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.

Doverphos® S-9228

by Dover Chemical (ICC Industries)

Doverphos® S-9228 by Dover Chemical (ICC Industries) is bis (2,4-dicumylphenyl) pentaerythritol diphosphite. Acts as an antioxidant. Provides excellent hydrolytic stability without the addition of inert products or triisopropanol amine. It exhibits similar color performance as DDPD and other similar pentaerythritol diphosphites. Because of its high melting point Doverphos® S-9228 can be utilized in applications that require processing at elevated temperatures.

Doverphos® S-9228T

by Dover Chemical (ICC Industries)

Doverphos® S-9228T by Dover Chemical (ICC Industries) is bis (2,4-dicumylphenyl) pentaerythritol diphosphite with 1% triisopropanol amine. It is free-flowing solid phosphite antioxidant. It offers hydrolytic stability and outstanding performance in stabilizing polymers against melt flow degradation & color change. Doverphos® S-9228T in polymer systems has improved permanence where other phosphites may lose activity even when encapsulated in the polymer or in one-pack blends. It does not hydrolyze and cause black specks as do other phosphites.
