MARLEX HDPE HHM 5502

Lightweight, Stiff, and FDA-Compliant HDPE for Precision Blow Molding Applications

Imagine a material that’s as strong as it is lightweight — perfect for containers that need to hold everything from household cleaners to pharmaceuticals without adding unnecessary bulk. That’s exactly what Marlex® HHM 5502 delivers. This high-density polyethylene (HDPE) resin is specifically engineered as a hexene copolymer for light-weight blow molding applications. Whether you’re designing bottles, jars, or medical containers, HHM 5502 offers excellent stiffness and processability, allowing manufacturers to create durable, thin-walled products that are both cost-effective and environmentally sustainable. Its tailored molecular structure ensures consistent performance during the blow molding process, making it a favorite among engineers who demand precision and reliability.

What sets Marlex® HHM 5502 apart is its blend of toughness, chemical resistance, and safety compliance. It meets stringent food-contact regulations including FDA 21 CFR 177.1520 and ASTM D4976, making it ideal for packaging that comes into contact with food, beverages, or pharmaceuticals. Beyond safety, this HDPE copolymer boasts exceptional impact strength and flexibility, even at low temperatures — crucial for products shipped in varying climates. It’s also non-toxic and hypoallergenic, with no skin or eye irritation reported under normal handling conditions. Plus, it’s recyclable, helping brands meet sustainability goals without sacrificing performance. For industries like automotive, consumer goods, and healthcare, HHM 5502 provides peace of mind through its proven track record and compliance with global standards.

In practical terms, Marlex® HHM 5502 shines in real-world applications where durability meets efficiency. Think toolboxes that won’t crack under pressure, furniture components that resist daily wear, or medical vials that protect sensitive contents. Its physical properties — such as a density of 0.955 g/cm³, tensile strength of 27 MPa, and elongation at break over 600% — make it highly versatile across manufacturing processes. Unit test results confirm its consistency: melt index at 0.35 g/10 min, heat deflection temperature at 79°C, and brittleness temperature below -75°C. These values ensure reliable processing and end-use performance. Whether you’re scaling up production or innovating new product designs, HHM 5502 gives you the confidence to push boundaries — all while staying compliant, safe, and sustainable.
