Product Introduction of  FEP Emulsion Impregnation DS603A/B

Influence of Die on FEP Emulsion Impregnation coating tightness

The selection of die is usually based on experience and conventional methods: a ring plastic section at the exit of the die core and the sleeve is formed by a certain stretch coating on the on-line core to form a small section. In the actual coating process, because the linear velocity is larger than the extrusion speed of the material flow, the drawing is formed, and a cone is formed behind the die. When the amount of glue is constant, the taper of the cone with different linear velocity is also different, and the circumferential tangent is reduced in a certain proportion. The extruded tube is stretched from a large ring to a small ring. The linear speed is fast and the small ring moves forward. You can avoid it only if you have the right drawing ratio. Free from conical tear, pinhole, crack, loose wrap and so on. In the process of FEP wire coating, the normal drawing ratio is 50: 1 ~ 150: 1, A higher DDR usually requires a higher linear speed, and the appropriate tensile balance ratio (DRBs) is 0.9-1.05

Package,Transportation and Storage of FEP Emulsion Impregnation DS603A/B

Packed in plastic drums,and in hard circular barrels outside. Net Weight is 25kg per drum.

FEP Emulsion must be stored under frost proof environment under optimum 5-30℃ temperature; It should be homogenized once or twice a month by gentle rolling or stirring when storing or before using;
The below action will cause FEP dispersion demulsification:
Under 0℃ or over 40℃ temperature
Adjust viscosity by untreated water with electrolytic
Rapid mixing FEP dispersion
Add other electrolytic or water soluble additives and overload organic acid
