DSP-601 is formed with Ethylene-vinyl acetate esters copolymers with a PHE-VA code and soluble in benzene, toluene, xylene and diesel organic solvent. It’s mainly used as PPD for the wax contained crude during the gathering, storage and transport. The freezing point reducing value of crude containing wax is changing with the hydrolysid degree rate rapidly. The wax (paraffin) dropping and removal performance is best at a 50% hydrolysid degree rate and this performance is affected by ester content in the EVA raw material greatly.
