ABSTRACT:
Liquid polyester plasticizers, having a hydroxyl value of at least 25, are incorporated into vinyl resins, such as PVC, which are formed into gaskets for use on appliances made from textured coil stock, especially refrigerators or freezers. These plasticizers have no detrimental effect on the relatively soft surface coatings on such appliances.
