New Thermal Stabilizer for Food Contact Applications

 July 2015 - Dover Chemical Corporation has received FDA clearance for Doverphos® LGP-11® antioxidant as a thermal stabilizer in single- and repeated-use linear low density polyethylene (LLDPE) films and high density polyethylene (HDPE) articles in contact with all food types under Conditions of Use A through H, at loading levels in polymer up to 2000 ppm. 

Doverphos® LGP-11® is a proprietary high molecular weight phosphite that is suitable as an alternative to TNPP, or any other phosphite additive in any polyolefin application.  Doverphos® LGP-11® is also recommended for use in other resin systems such as SBS, SBR, urethanes and PVC. Doverphos® LGP-11® is unique in that it contains no alkylphenol components, has superior color hold, has low migration due to its polymeric nature, and is composed of biodegradable raw materials.

“The fact that LGP-11® is not produced from alkylphenols provides benefits that are unprecedented by any other phosphite on the market today,” noted Dr. Mick Jakupca, Director of Research and Development at Dover Chemical Corporation. “Most antioxidants are composed of or contain alkylphenols. Alkylphenols, as a general class of chemicals, are a focus of both consumer and regulatory organizations. Doverphos® LGP-11® was engineered to offer the global plastics market a viable long-term alkylphenol-free alternative chemistry.

“Dover Chemical Corporation has a long history of developing truly novel products and processes that address the concerns of our customers and consumers. The polymeric nature of this product has routinely demonstrated in laboratory and large-scale testing the reduction and/or elimination of plateout and blooming of the antioxidant in blown and cast film applications, which has been an industry-wide problem for decades.”

Matthew Fender, Business Manager of Polymer Additives, added: “Dover Chemical Corporation, as do most of our customers, strongly believe this new platform of Liquid  Green Chemistry, which contains no alkylphenols, is a paradigm leap forward for the future of antioxidant systems for all polymers globally. Doverphos® LGP-11® was designed to meet long-term global market needs and receiving full FDA clearance is certainly an important milestone for all of us.”
