Fuel in low temperature environment for a long time, will cause wax precipitation formation ofcrystals, which will continue to gather, forming clumps, even using the diesel jams mesh easily. This product contains the wax precipitation agent, one of the effective components lead to exclusion between paraffin wax crystallization and charge, to a smaller volume, paraffin wax crystal structure is loose, the distribution more uniform, prevent paraffin wax crystal agglomeration, thereby enhancing the performance of the diesel cold flow. Used alone, in fact, the wax precipitation resistant agent does not improve diesel low temperature fluidity, it is always used with diesel cold flow improver. This product is made from diesel cold flow improver and wax precipitation resistant agent according to certain proportion of compound. It can overcome shortcomings arising from separate to add a certain product, make the flow properties of diesel fuel to improve, to reduce the effect of solidifying point.
