Cold-resistant plasticizer, compatible with most resins and synthetic rubbers, can be used as the main plasticizer. The product is non-toxic and can be used for packaging materials in contact with food, and the product feels good. This product is used as a plasticizing Chemicalbook agent for many synthetic rubbers, which can make the products have excellent low temperature performance and oil resistance. The main disadvantage of this product is that it has a large volatile loss and is easily drawn out by water, soapy water and detergent solutions, so it is often used in combination with phthalate plasticizers.
