LLDPE COMAI Comai 745-4 ASUse performance
First, the material properties: corrosion resistance, electrical insulating properties (especially the high-frequency insulation) fine, can be chlorinated irradiation modification, available glass fiber reinforced and the melting point of the low-pressure polyethylene, rigidity, hardness and high strength, absorbentis small, has good electrical properties and radiation resistance; the softness of the high-pressure polyethylene, elongation, impact strength and good permeability; UHMWPE impact strength, fatigue resistance, wear and pressure polyethylenesuitable for the production of corrosion-resistant parts and insulating parts; suitable for production of high-pressure polyethylene film; ultra-high molecular weight polyethylene suitable for production of shock absorption, abrasion resistance and transmission parts.
Forming properties: 1. Crystalline material, moisture absorption is small, and not to be fully dry, the fluidity excellent liquidity pressure sensitive when it is appropriate to the high-pressure injection molding, the material temperature uniformity, fast filling, packing full. Should not be poured directly mouth to prevent uneven shrinkage, internal stress increases. attention to the ｓｅｌｅｃｔion of the location of the gate to prevent to generate shrinkage and deformation .2. shrink the scope and value of contraction, clear direction, easy to deform and warp. cooling rate should slow, mold set of cold-slug, and cooling system .3. heating time not too long, otherwise it will decompose burns .4 soft plastic parts lighter side of the groove can be forcibly stripping .5. might occur financial body rupture, should not be in contact with the organic solvent, to prevent cracking.
PE plastic Usage: Available blow molding, extrusion, injection molding and other processing methods are widely used in the manufacture of film, hollow products, fibers and daily groceries. In order to improve the stability of the polyethylene to ultraviolet light and oxidation, improve the performance of the processing and use of the actual production, must be added to a small amount of plastic additives. The ultraviolet absorber used for the o-hydroxy-benzophenone, or alkoxy derivative thereof, etc., and the carbon black is an excellent UV shielding agent. Furthermore, adding antioxidants, lubricants, coloring agents and the like, so that the range of applications of polyethylene more expanded
