Bis(2-propyl heptyl) Phthalate
Bis(2-propyl heptyl) Phthalate, abbreviated as DPHP, has a molecular formula of C28H46O4, with a relative molecular mass of 446.7. It is a colorless, transparent, viscous oily liquid with a slight odor. It has low toxicity and low volatility. It is highly stable and soluble in most organic solvents. It has good compatibility with PVC and has a higher plasticization efficiency than DOTP. Its electrical insulation performance is the same as DOTP, but it has the lowest volatility and can withstand higher temperatures, and has the highest safety. DPHP can be used alone or in combination with other plasticizers. It can also replace DBP, DINP, BBP, etc. as a plasticizer. It is widely used in plastic and rubber production and is one of the best plasticizers among the phthalate esters in terms of performance. As a plasticizer, DPHP can further improve the performance of PVC and expand its application range. In the face of the increasing requirements for PVC performance and environmental protection in the market, the market space for DPHP is continuously expanding.
