ENVIRONMENTAL-FRIENDLY FEP DISPERSION
FEP Dispersion DS603 is the copolymer of TFE and HFP. Environmental-friendly perfluorinated ethylene-propylene copolymer dispersion is a water-phase dispersion solution stabilized by non-ionic surfactants which canbe degraded during processing and will not cause pollution. Its products have excellent thermal stability, corrosion resistance, excellent chemical inertness, good electrical insulation, and low coefficient of friction. It can be used at temperature up to 200°C continuously. It is inert to almost all industrial chemicals and solvents.

Application
It can be used for coating and impregnation. It is also suitable for processing many products，including heat resistant PTFE impregnation fiber surface coating, PWB, or electrical insulation materials,injection film,or chemical isolation materials,as well as PTFE/FEP mutual connection melt coating,and for the production of glass cloth composite antifouling coating，and polymide composite as high insulation membrane.
Attention
1.The processing temperature should not exceed 400℃ to prevent toxic gas from releasing. 2.Stirring the stored product two or three times a month to avoid any possible precipitation.
