Typical Applications of Lotrene HDPE TR 571

Large Container Manufacturing. With its excellent rigidity, strength, stress crack resistance, and good processing properties, Lotrene TR 571 is widely used in the manufacture of various large containers, such as plastic storage tanks, chemical drums, and transport tanks. These containers are used to store and transport a variety of liquids and solids, playing a vital role in the chemical, petroleum, food, and pharmaceutical industries. In the chemical industry, large tanks used to store corrosive chemicals such as acids and alkalis can be protected from leakage and damage by HDPE TR 571, ensuring long-term chemical exposure and ensuring production safety.
Industrial Packaging. In the industrial packaging sector, HDPE TR 571 is commonly used in heavy-duty packaging bags and pallet packaging. Its high strength and excellent chemical resistance effectively protect the products contained within from damage during storage and transportation, and can withstand various harsh environmental conditions. For packaging heavy goods like metal products and machinery parts that are susceptible to abrasion, packaging materials made from Lotrene TR 571 resin provide reliable protection and reduce product damage during transportation.
Building materials. HDPE TR 571 resin can be used to manufacture pipes, panels, and other materials for construction. These materials are widely used in water supply and drainage systems, waterproofing, sound insulation, and thermal insulation. Its chemical resistance and high stress cracking resistance ensure that building pipes withstand long-term corrosion from waterborne chemicals, preventing breakage and leakage, thus ensuring the proper functioning of water supply and drainage systems. Building panels maintain stable performance under various environmental conditions, providing excellent waterproofing, sound insulation, and thermal insulation for buildings.
Agricultural facilities. In the agricultural sector, Lotrene HDPE TR 571 can be used to manufacture drip irrigation pipes, sprinkler equipment components, and support structures for greenhouses. Drip irrigation pipes require excellent corrosion resistance and environmental stress cracking resistance to adapt to the complex soil and water conditions found in farmland. Lotrene TR 571 resin meets these requirements, ensuring the long-term stable operation of drip irrigation systems and improving water resource utilization efficiency. Agricultural greenhouse support structures must possess sufficient strength and rigidity to withstand the weight of the film and the impact of natural disasters such as wind and rain. Support structures made from Lotrene TR 571 provide reliable support for greenhouses and safeguard the growth environment of crops.
Food packaging. Because Lotrene TR 571 complies with relevant food contact standards, such as FDA regulation 21 CFR 177.1520, it can be used directly in food packaging. Its excellent chemical stability prevents the migration of harmful substances into food, ensuring the safety and quality of food during storage and transportation. It can be used in packaging materials such as food bags and containers, providing the food industry with reliable packaging solutions that protect consumer health.

Product Performance

Excellent Rigidity and Strength. Lotrene TR 571 is an ultra-high molecular weight ethylene copolymer with a highly crystalline structure, resulting in exceptional rigidity. This property enables products made from it to maintain a stable shape and resist deformation even under significant pressure and weight. For example, when manufacturing large containers, its rigidity ensures that the container, when filled, can withstand its own weight as well as the forces encountered during handling, providing a solid foundation for safe storage and transportation of products. Furthermore, the resin exhibits high strength and excellent resistance to forces such as tension and bending, reducing the risk of cracking or damage during use and significantly enhancing product durability.
Excellent Melt Strength. During processing, HDPE TR 571 resin exhibits excellent melt strength. While molten, the resin maintains a certain strength and stability, making it less susceptible to melt fracture and uneven flow. This characteristic is crucial for demanding molding applications, such as blow molding of complex containers. Excellent melt strength ensures that the resin evenly wraps around the mold during the blow molding process, resulting in products with uniform wall thickness and consistent quality, effectively improving production efficiency and quality.
Excellent processability. Lotrene TR 571 is well-suited for a variety of processing techniques, including injection molding, blow molding, and extrusion. In injection molding, it quickly fills the mold cavity and forms high-precision parts. In blow molding, it is easy to operate, enabling the production of hollow plastic products in a variety of sizes and shapes. Extrusion also operates smoothly, producing reliable quality products such as pipes and sheets. This wide range of processing adaptability allows manufacturers to flexibly select the appropriate processing method based on different product requirements, broadening the product’s application range. Furthermore, this resin causes minimal wear and tear on processing equipment, extending the life of processing equipment and reducing production costs.
Excellent chemical resistance. This resin exhibits excellent resistance to most common chemicals, including acids, bases, salt solutions, and various organic solvents. When exposed to these chemicals, Lotrene TR 571 resin’s molecular structure remains intact, and the product’s performance remains unaffected. This property makes it widely used in packaging applications in the chemical, pharmaceutical, and food industries. It can safely store and transport a variety of chemical products, pharmaceuticals, and corrosive food additives, effectively preventing leakage from chemical corrosion, and thus ensuring product quality and safety.
Outstanding stress crack resistance. Lotrene TR 571 resin exhibits outstanding resistance to environmental stress cracking (ESCR). Even under challenging environmental conditions, such as temperature fluctuations, humidity fluctuations, and external stresses, it maintains its integrity and resists cracking. Plastic products used outdoors for extended periods, such as large water storage tanks and industrial pipes, are often exposed to harsh environments and various stresses. Lotrene TR 571 resin’s high stress crack resistance ensures that these products maintain their performance over extended periods of use, reducing maintenance and replacement costs and increasing product reliability and service life.
