HiTEC® 4557 has been developed to improve the low temperature properties of narrow boiling distillates and delivers the following benefits:

Recommended Dosage

HiTEC® 4557 is used to allow fuel manufacturers to cost effectively meet CFPP & Pour point specifications. The CFPP specification dominates the market and the CFPP level varies by geographic region. Treat-rate may vary depending on base fuels. However, the treat-rate should be in the range of 100 to 500 ppmv. For secondary treatment we would recommend a treat-rate of 500 ppmv.
