The Dioctyl Terephthalate (DOTP) is a versatile plasticizer used to improve the flexibility, durability, and processing characteristics of various polymer materials. Unlike traditional phthalate plasticizers, DOTP is considered non-toxic and safer for human health, making it widely used in consumer products, medical devices, and food-contact materials. It is commonly added to polyvinyl chloride (PVC) to create flexible sheets, cables, flooring, and films. DOTP enhances flexibility without compromising the mechanical properties of the material, offering excellent low-temperature performance and resistance to aging, heat, and UV exposure. It is also resistant to extraction by water, oil, and chemicals, which makes it suitable for outdoor and industrial applications. In addition to PVC, DOTP can be used in coatings, adhesives, and sealants to improve workability and flexibility. With increasing regulatory pressure on traditional phthalates, DOTP has emerged as a preferred eco-friendly alternative for manufacturers seeking safe, high-performance plasticizers. Its non-toxic nature, thermal stability, and compatibility with various polymers make it a reliable choice for industries ranging from construction to healthcare and consumer products.
