Pour Pont Depressant


T803B pour point depressant is long chain α-olefin polymer under Ziegler-Natta catalyst polymerization. Its MW is relatively small. This product viscosity is not so high. So it has better shear stability. Also it could be used in base oils with various wax content and viscosity to produce engine oil, hydraulic fluid and other lube oil products. Add 1% of WX803B into HVI 150 base oil (pour point -15ºC) could get the pour point around -35ºC.

Storage and Handling:

In the storage, loading/unloading and blending. The maximum temperature is 65ºC; if in long time storage we suggest the Max. Temperature is 50ºC. Avoid contact with water and moist air. Packing in 200L drum, net weight is 185Kg/drum. The warranty period is 24 months.
