Plastic PVC Material Extrusion process
The flame retardant pvc compound can be used with a regular PVC extruder. With a screw length to diameter ratio of L/D ≥ 20 Taking machine φ 90 as an example, pvc cable sheath material recommended to place two layers of filter screens with 40 mesh/80 mesh on the mesh plate. With the best extrusion surface being smooth and the cross-section having no pores.
