Plasticizers that maintain color during heat aging

Abstract

The present disclosure is directed to a plasticizer, a polymeric composition containing the plasticizer, and conductors coated with the polymeric composition. The plasticizer includes a blend of an epoxidized soybean oil and a trans-esterified epoxidized fatty acid methyl ester. The trans-esterified epoxidized fatty acid methyl ester has an oxirane value greater than or equal to 6.8 %. The plasticizer, the polymeric composition, and the coated conductor retain color during heat aging.

Description

technical field [0001] The present disclosure relates to plasticizers having color retention during heat aging. Background technique [0002] Plasticizers are compounds or mixtures of compounds added to polymer resins to impart softness and flexibility. Phthalate diesters (also known as "phthalates") are known plasticizers in many flexible polymer products, such as those formed from polyvinyl chloride (PVC) and other vinyl polymers polymer products. Examples of commonly used phthalate plasticizers include diisononyl phthalate (DINP), diallyl phthalate (DAP), di-2-ethylhexyl phthalate ester (DEHP), dioctyl phthalate (DOP) and diisodecyl phthalate (DIDP). Other commonly used plasticizers for high temperature applications are trimellitates and adipate polyesters. A mixture of plasticizers is usually used to obtain the best properties. [0003] Phthalate plasticizers are currently under intense scrutiny by public interest groups concerned about the adverse ) potential adve...
