Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device for medium-density polyethylene sheathing materials. Background Art

[0002] Polyethylene sheath material is based on polyvinyl chloride resin, with plasticizers, stabilizers, colorants and special additives added to it. It is mixed, plasticized and granulated to form a granular material to form the sheath material raw material, which is then extruded to form the cable sheath. It generally includes high-density polyethylene sheath material, medium-density polyethylene sheath material and low-density / linear low-density sliding sleeve.
