Passed SGS testing, no phthalate; it is a kind of environmental friendly and new type plasticizer. DOTP has better physical and mechanical performance than DOP. In addition, it has excellent electrical resistance, heat resistance, low-temperature volatility, low glass transition temperature and etc.


It is widely used in cable material and PVC soft-quality products; it is also used as PVC plasticizer, polyvinyl butyral, butadiene-acrylonitrile rubber and nitrocellulose plasticizer; it is used in synthesis of coating additive, precise instrument lubricating agent and paper softening agent.
