Black medium-density environmental friendly recycled polyethylene sheath material MDPE adopts a special base material formula and adds a variety of additives. MDPE is made by comprehensively improving polyethylene and can meet the requirements of different cables. Injection molding grade MDPE plastic sheath material can be used to make optical cable sheath, overhead cable insulation sheath and other environments with strict requirements on sheath strength and wear resistance.
Medium density polyethylene MDPE has excellent weather resistance;
environmental friendly stress crack resistance;
Recycled PE has extrusion processability;
optical cable sheath, overhead cable insulation sheath and other environments with strict requirements on sheath strength and wear resistance.
