MDPE (Medium density polyethylene)
Medium density polyethylene (MDPE) is copolymerized with alpha olefin in the synthesis process, and the density is controlled. [Combustion characteristics] Flammable, can continue to burn after the fire, the upper end of the flame is yellow, the lower end is blue, burning will melt, there is liquid dripping, no black smoke, at the same time, emit the smell of paraffin burning. 【 Main advantages 】 Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP. [Main disadvantages] Poor mechanical properties, poor air permeability, easy deformation, easy aging, easy brittleness, brittleness lower than PP, easy stress cracking, low surface hardness, easy scratching. Difficult to print, printing, need to carry out surface discharge treatment, can not be electroplated, surface luster. [Application] For extruding packaging film, rope, woven bag, fishing net, water pipe; Injection low-grade daily necessities and shells, non-load-bearing components, plastic boxes, turnover boxes; Extrusion blow molded containers, hollow products, bottles.
