TOPM has good electrical insulation, so it can be used as a 105~120 ºC heat-resistant cable. It is suitable for PVC plastic products with special heat resistance requirements. It is a super heat-resistant and durable plasticizer for PVC. At the same time, as a non-toxic environmental plasticizer, it is used in medical plastic products, food packaging, children's plastic toys, and other industries. As a plasticizer of medical plastic products, it has much less toxicity than DOP and has no adverse effect on physiological processes. Medical plastic products using TOPM as plasticizers have been widely used in clinical medicine, scientific research, and related fields. There are many kinds of products, including tubes, flexible tubes, bags, bags, liquid conducting tubes, films, sheaths, various human organ substitutes, and various parts of medical and testing instruments.
