Doverphos® Lgp phosphite stabilizers
The Difference in Phosphites is Clear
Doverphos® LGP stabilizers are purpose-designed polymeric phosphites that deliver superior performance, low migration, and regulatory confidence across a wide range of applications.
At the center of the portfolio is Doverphos® LGP-12, a liquid, high molecular weight polymeric phosphite that combines outstanding stabilization with ultra-low migration—making it ideal for food-contact packaging, PCR/PIR applications, and next-generation polyolefin processing.
The LGP platform has now expanded into a full family of solutions:
Doverphos® LGP-12
Alkylphenol-free, TNPP-free, FDA-approved liquid antioxidant, with no NIAS concerns, that also functions as a PFAS-free polymer processing aid (PPA). Improves MFI stability, reduces gel formation, and minimizes die lip buildup and plate-out for cleaner, more efficient production.
DoverClear™
PFAS-free, silicone-free masterbatch formulations for film extrusion. Improves optical clarity, eliminates melt fracture, and reduces buildup, enabling smoother films and higher throughput.
DoverCycle™
The newest addition, designed for upcycling recycled polyolefins. Enhances recyclate quality, maintains MFI stability, and enables resin processors and brand owners to incorporate higher recycled content without sacrificing performance.
Doverphos® LGP stabilizers are used in polyolefins, PVC, coatings, adhesives, rubber, elastomers, engineering plastics, and PUF. They meet stringent antioxidant requirements while delivering excellent color, thermal, and hydrolytic stability.
