Rotomolding LLDPE

Rotomolding LLDPE is a non-toxic, odorless, and milky white particle with a density of 0.918-0.935g/cm3. Compared with LDPE, it has higher softening and melting temperatures, and has advantages such as high strength, toughness, rigidity, heat resistance, and cold resistance. It also has good resistance to environmental stress cracking, impact strength, tear strength, and can withstand acid, alkali, organic solvents, etc. It is widely used in industries, agriculture, medicine, health, and daily necessities.

What are the application areas of Rotomolding LLDPE?

Rotomolding LLDPE has penetrated into most traditional markets of polyethylene, including films, molds, pipes, and wires and cables. Anti leakage plastic film is a newly developed LLDPE market. Geomembrane, a large extruded sheet material used as a waste landfill and waste pool liner to prevent leakage or pollution of surrounding areas.

Some of LLDPE's film markets, such as production bags, garbage bags, elastic packaging, industrial liners, towel liners, and shopping bags, utilize the advantages of this resin after improving strength and toughness. Transparent film. The penetration resistance and stiffness of LDPE film do not significantly affect the transparency of the film. Injection molding and roll molding are the two largest molding applications of LLDPE. The superior toughness, low temperature, and impact strength of this resin are theoretically suitable for waste bins, toys, and refrigerated appliances. In addition, LLDPE's high resistance to environmental stress cracking makes it suitable for injection molded lids in contact with oily foods, roll forming waste containers, fuel tanks, and chemical tanks. The market for application in pipe and wire and cable coatings is relatively small, where LLDPE's high fracture strength and resistance to environmental stress cracking can meet the requirements. 65% to 70% of LLDPE is used for making thin films.

The LLDPE polymer generated during the copolymerization process has a narrower molecular weight distribution than general LDPE, and its linear structure gives it different rheological properties. The melt flow characteristics of LLDPE meet the requirements of new processes, especially with the use of thin film extrusion technology, which can produce high-quality LLDPE products. LLDPE is applied to all traditional markets of polyethylene, enhancing its resistance to elongation, penetration, impact, and tear. Its excellent resistance to environmental stress cracking, low temperature impact, and warping make LLDPE attractive for pipe, sheet extrusion, and all molding applications. The latest application of LLDPE is as a lining layer for waste landfill and waste liquid tank as a plastic film.

Rotomolding HDPE

Rotomolding HDPE is a white powder or granular product. Non toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125-135 ℃, and a usage temperature of up to 100 ℃; Hardness, tensile strength, and creep resistance are superior to low-density polyethylene; Good wear resistance, electrical insulation, toughness, and cold resistance; Good chemical stability, insoluble in any organic solvent at room temperature, resistant to corrosion by acids, alkalis, and various salts; The film has low permeability to water vapor and air, and low water absorption; The aging resistance is poor, and the environmental stress cracking resistance is not as good as low-density polyethylene. Especially, thermal oxidation can cause its performance to decline. Therefore, antioxidants and UV absorbers need to be added to the resin to improve this deficiency. High density polyethylene film has a lower thermal deformation temperature under stress, so attention should be paid when applying it.
