What are LLDPE Plastic - R40039E

In the field of large-scale rotational molding products, how to balance UV resistance, impact resistance and structural stability is the core concern of engineers when selecting materials. The LLDPE R40039E launched by Saudi Basic is precisely a linear low-density polyethylene (LLDPE) plastic raw material tailor-made for outdoor and high-load application scenarios.

01 | Material performance highlights: stable, durable, and easy to process

LLDPE R40039E demonstrates multiple balanced properties, making it stand out among numerous rotational molding grade plastics:

Outstanding UV resistance: Equipped with a UV stabilization system, it is suitable for long-term outdoor exposure and has excellent anti-aging performance.

Outstanding impact toughness: It can maintain ductility and impact strength even at low temperatures, effectively preventing brittle cracking.

Moderate rigidity and flexibility, structural strength: Good bending strength and tensile performance, which can meet the structural requirements of large water tanks, etc.

High forming accuracy: Low warpage rate, small deformation during the rotational molding process, and easy to control complex structures.

Strong resistance to stress cracking: It has passed the ASTM D1693 test and has good resistance to environmental stress damage.

Process-friendly design: The melt index is 3.5g /10min, ensuring a balance between melt stability and rotational molding fluidity.

02 | Application fields: Diversified coverage from water tanks to outdoor facilities

Industrial/agricultural water tanks: Suitable for liquid storage and transportation containers of various capacities, adaptable to outdoor environments exposed to sun and rain.

Large containers: Large-volume container structural components used in agriculture, chemical engineering and other fields, ensuring both rigidity and toughness.

Rotational molding outdoor equipment: such as outdoor trash cans, seats, water towers, pipe joints, etc., which require stable shape and anti-aging.

Special buried/lined products: Reliable and durable even when used under pressure for a long time.
