Applications:
DOTP plasticizer is a a good main plasticizer of PVC plastics. Compared to DOP, it offer better heat , anti-freezing, not volatile,anti-taking and flexibility. Because of low volatility, can be used to produce wire and cable working in low temperature,and is widely used in 70 ° C -resisting cable (Standards of International Electrotechnical Commission) and other soft.PVC products. Besides, it also can be used in leatherette and film.as plasticizer of PE alcohol butyral, acrylonitrile-butadiene rubber, cellulose nitrate and synthetic rubber. It also can be used as coating additives,lubricant of precision instruments, lubricant additives, or softener of paper.
Package and storage
