1. Product Description
Dioctyl Terephthalate (DOTP), CAS No. 6422-86-2 (also known as Di-(2-ethylhexyl) terephthalate), is a high-performance, non-phthalate plasticizer derived from terephthalic acid.
This colorless to light-yellow liquid is widely recognized as an eco-friendly alternative to traditional phthalate plasticizers. Therefore, choosing a reliable dioctyl terephthalate supplier ensures consistent quality and performance for industrial applications.
DOTP primarily serves as a primary plasticizer for PVC, and is commonly used in 70 °C heat-resistant cable compounds, soft PVC products, and synthetic leather films.
Thanks to its excellent compatibility, it is also makes it suitable for acrylonitrile derivatives, polyvinyl butyral (PVB), nitrile rubber, and cellulose nitrate.
Furthermore, DOTP finds applications as a plasticizer for synthetic rubber, a coating additive, a precision instrument lubricant, a lubricant additive, and a paper softener.
