Injection Molding
ExxonMobil LL 6201XR: Widely used in injection molding due to its high flowability and wide processing temperature range, which allows for precise control during manufacturing. Key applications include:
- Lids and Closures: The resin’s high flow and gloss make it ideal for producing thin-walled lids for food packaging, cosmetics, and pharmaceuticals. e
- Thin-Wall Articles: Suitable for manufacturing lightweight, durable consumer goods such as containers, plastic boxes, and turnover boxes. The resin’s toughness and stiffness ensure structural integrity in thin-walled designs.
- Housewares: Used in the production of household items like storage bins, kitchenware, and utensil handles, where its combination of gloss, toughness, and low-temperature performance enhances product longevity.
- Non-Load-Bearing Components: Applied in low-end daily necessities and shells, where cost-effectiveness and durability are critical.
Processing Notes: During injection molding, the resin supports a wide temperature control range. Typical settings include:- Nozzle temperature: Adjusted based on equipment and part design.
- Barrel temperatures: Flexible across sections to optimize flow and minimize defects.
- Mold temperature: Tunable to achieve desired surface finish and cycle times.
2. Extrusion
The resin’s excellent processability: Makes it suitable for extrusion processes, producing films, pipes, and other products. Applications include:
- Packaging Films: LL 6201XR is used to extrude packaging films for food and non-food items. Its toughness and ESCR provide resistance to punctures and environmental stress, while its gloss enhances visual appeal.
- Ropes and Woven Bags: The resin’s strength and flexibility make it ideal for producing ropes, fishing nets, and woven bags used in agriculture, construction, and logistics.
- Water Pipes: Its durability, low-temperature performance, and resistance to environmental stress cracking make it suitable for non-pressure water pipes and irrigation systems.
- Extrusion Blow Molding: Used to manufacture hollow products such as bottles and containers, leveraging its high flow and toughness for uniform wall thickness and structural integrity.
Processing Notes: The resin’s high flowability ensures consistent extrusion, with adjustable temperatures to suit specific extrusion equipment and product requirements.
3. Wire and Cable Compounding
LL 6201XR: Specifically formulated for wire and cable applications as a masterbatch base resin. Its key features include:
