Product Details

      FEP Extrusion Resin has two characteristics in processing, that is, it has the tendency of melting rupture and the extremely high extensibility in melting state. In order to minimize or improve melting rupture and increase productivity in wire and cable production, the following such measures are usually taken: first, the extrusion die is used to expand the opening of the mold to slow down the flow rate of the polymer in the die. To extrude the resin at a moderate extrusion rate below the critical shear rate and to increase productivity; second, to increase the temperature of the melt resin as much as possible, without causing the resin to decompose, in order to reduce the viscosity of the resin, Thus, the critical shear rate is increased.
