HiTEC® 4598

Specification and Distribution Additive

Key Performance Benefits

  • Depressing the pour point leading to reduced blockage in pipes and storage vessels
  • Modification of wax crystals allowing improved flow through filters
  • Improved low temperature operability by lowering the CFPP of treated fuel


The low temperature treatment of middle distillates can be challenging due to the varied qualities of fuel currently seen on the market. HiTEC® 4598 additive will effectively lower the Cold Filter Plugging Point (CFPP) and the pour point of treated fuels. HiTEC® 4598 cold flow improver is formulated to give optimum performance to allow you consistently and economically meet your target specification.

Recommended Dosage

HiTEC® 4598 additive 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 my vary depending on base fuel. 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.

Typical Characteristics
