MDPE is characterized by environmental stress cracking resistance and long-term strength retention. The relative density of MDPE is 0.926-0.953, the crystallinity is between 70% and 80%, the average molecular weight is 200,000, the tensile strength is 8-24 mpa, the elongation at break is 50%-60%, the melting temperature is 126-135ºC, and the melt flow rate is 0.1-35 g /10 min. Thermal deformation temperature (0.46 mpa)49-74ºC.
Its performance between high density polyethylene (HDPE) and low density polyethylene (LDPE), both maintain the rigidity of HDPE, and flexible LDPE, creep resistance, set the advantages of both in one, in the manufacture of pipe, pipe, communication and cable sheath has absolute advantage, so more and more attention by the market. Unique performance to establish the market position :MDPE because of its good resistance to environmental stress cracking, weldability and long service life, etc., in recent years, the application of rapid development, rapid increase in dosage, MDPE is considered to be the most suitable sheath material for communication cables, optical fibers and optical cables in the world.
