DOP is not environmentally friendly, mainly harmful to human body; Compared with DOTP, it has better plasticizing efficiency, higher tensile strength and softer products, so it is the most commonly used plasticizer.

DOTP is environmentally friendly and has low toxicity to human body; The plasticizing effect is slightly worse than DOP, and the product is hard. The highest volume resistance is 12 power. It has a broad application prospect in insulation materials such as cables. The temperature resistance of this DOTP is also slightly better.

Europe and America gradually replaced DOP plasticizer with environmentally friendly plasticizer. The annual growth rate of environmental protection plasticizer in China in 2065,438+08 is above 12%, and environmental protection plasticizer is the future trend.
