Fumarate Copolymer Pour Point Depressant
Fumarate ester copolymers are non-PMA pour point depressants that are particularly effective in Group I base oils and paraffinic stocks where PMA performance is limited. They are also used as wax crystal modifiers in diesel fuel and middle distillate additives. Their mechanism involves co-crystallization with wax, preventing the formation of continuous wax networks that restrict low-temperature flow. These products are valuable as pour point depressants in residual fuel oils and heavy bunker fuel treatments.

Области применения
- Group I base oil pour point improvement in engine and industrial oils
- Diesel fuel and middle distillate cold flow improver (CFPP)
- Residual fuel oil and marine bunker fuel treatment
- Heavy industrial lubricants based on paraffinic stocks
- Wax crystal modifier in crude oil pipeline transportation
Особенности продукта
- Superior performance in Group I and paraffinic base oils where PMA effectiveness is reduced
- Effective as both lubricant pour point depressant and fuel cold flow improver in one product
- Lower molecular weight enables easier blending and handling versus solid PPD products
- Complementary to PMA PPDs: used alone or in combination for optimized cold-temperature performance
