Do you know the processing flow of PE Plastic Tube Core?

PE Plastic Tube Core can be manufactured with a wide range of different processing methods. With ethylene as the main raw material, propylene, 1-butene, and hexene as copolymers, and under the action of a catalyst, a slurry polymerization or a gas phase polymerization process is used, and the obtained polymer is subjected to flash evaporation, separation, drying, granulation, etc. Process to obtain a finished product with uniform particles. Includes such as sheet extrusion, Film Tapes Plastic Core Tube, tube or profile extrusion, blow molding, injection molding and rotomolding.

Extrusion: Grades used for extrusion production generally have a melt index of less than 1 and a medium to wide MWD. During processing, a low MI can achieve a suitable melt strength. Wider grades are more suitable for extrusion because they have production speeds, lower die pressures and a reduced melt fracture tendency.

PE roll core pipe has many extrusion applications, such as wires, cables, hoses, pipes and profiles. Tubing applications range from small cross-section yellow pipes for natural gas to thick wall black pipes for industrial and urban pipelines with a diameter of 48 in. Large diameter hollow wall pipes are growing rapidly as a substitute for rainwater drainage pipes and other sewer lines made of concrete.

Sheets and thermoforming: The thermoforming linings of many large picnic refrigerators are made of PE cored tubing, which is tough, lightweight and durable. Other sheet and thermoformed products include fenders, tank linings, pan shields, shipping boxes and tanks. A large number of rapidly growing sheet applications are mulch or pool bottom villages, which are based on MDPE's toughness, chemical resistance and impermeability.

Blow molding: More than 1/3 of the core tube sold in the United States is used for blow molding. These range from bottles containing bleach, motor oil, detergents, milk and distilled water to large refrigerators, automotive fuel tanks and canisters. The characteristics of blow molding grades, such as melt strength, ES-CR and toughness, are similar to those used for sheet and thermoforming applications, so similar grades can be used.

Injection molding is often used to make smaller containers for packaging medicines, shampoos, cosmetics, and tapes. One advantage of this process is that the bottles are automatically cornered without the need for post-trimming steps like in general blow molding. The inner wall of PE core tube is smooth and does not scale. The equivalent surface roughness ratio of PE coil core pipe is 1/20 of that of steel pipe. PE pipe with the same pipe diameter, the same length and the same pressure has a flow capacity about 30% larger than that of steel pipe, so the economic advantage is obvious. Compared with metal pipes, PE coil core pipes can reduce engineering investment by about one third, and small-diameter pipes that can be coiled can further reduce project costs. The performance of medium density polyethylene is between high and low density polyethylene, which not only maintains the rigidity and strength of high density polyethylene, but also has good flexibility and creep resistance, and the higher density polyethylene is hotter. The characteristics of excellent fusion connection are conducive to the installation of plastic pipes. We are Tapes PE Pipe Supplier, welcome to consult.
