DOTP has good electrical and thermal resistance. It can replace DOP in PVC plastic electric wire sheath, and can also be used in the production of artificial leather film. In addition, it has excellent compatibility and can also be used for plasticization of acry lonitril derivatives, polyvinyl butyral, nitrile rubber, nitr cellulose, and the like.And it plays a role in improving the hardness and deformability of the product, and can be used as a softener in products such as nitrile rubber, neoprene rubber, EPDM rubber and the like. It is especially used in cable materials with good plasticizing effect and low volatility. It is widely used in various products requiring heat resistance and high insulation. It is an ideal plasticizing for producing temperature-resistant 70C cable materials and other volatile PVC products Agent.
