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
Packed in 200 liter galvanized iron drum,net weight 200 kg/drum.Stored at dry,shady,ventilated place.
1.Dioctyl terephthalate/DOTP is low temperature plasticizer
2.DOTP plasticizer mainly used on cable,wire,leahter
3.DOTP plasticizer usually used with other plasticizer together
