Acetylated monoglyceride of 12-hydroxystearic acid and blends with epoxidized fatty acid esters

摘要

The present disclosure is directed to plasticizer compositions. A composition is provided which includes a castor-free acetylated glyceride of 12-hydroxystearic acid (AGHA) having a hydroxyl number from 0 to less than 15. The castor-free AGHA finds application in coatings for wire and cable.

1. A coated conductor comprising:
a conductor; and a coating on the metal conductor, the coating comprising a phthalate-free polymeric composition comprising (A) a single polymeric resin consisting of a polyvinyl chloride and (B) a plasticizer composition comprising
(i) from 30 wt % to 99 wt % of a castor-free primary plasticizer comprising acetylated monoglyceride of 12-hydroxystearic acid (AMHA), acetylated diglyceride of 12-hydroxystearic acid (ATHA), acetylated triglyceride of 12-hydroxystearic acid (ATHA), triacetin, and glycerol, the primary plasticizer having a hydroxyl number from 0 to less than 15 as measured in accordance with DIN 53240 and a temperature of 5% mass loss from 150° C. to 190° C. determined using TG/DTA 220; and (ii) from 70 wt % to 1 wt % of a second plasticizer based on total weight of the plasticizer composition comprising an epoxidized fatty acid ester; wherein the polymeric composition has a tensile elongation retention greater than 20% after 168 hours heat aging at 136° C. as measured on dog bones cut from 30 mil thick plaques in accordance with ASTM D638.
