Dioctyl terephthalate (DOTP) is a plasticizer that can be used in the production of high flame retardant, non-halogen, and low smoke fire retardant tape. DOTP is a non-toxic and environmentally friendly plasticizer that offers good flame retardancy and low smoke emission properties when used in combination with other flame retardant materials. The tape made with DOTP can be used in a variety of applications, including electrical insulation, communication cables, and power cables, where flame retardancy and low smoke emission are important safety considerations.
