MARLEX HHM 5502BN POLYETHYLENE

MARLEX HHM 5502BN POLYETHYLENE

MARLEX HHM 5502BN Polyethylene is a high molecular weight, ethylene-hexene copolymer high-density polyethylene (HDPE) resin manufactured by Chevron Phillips Chemical Company[cite: 14]. Tailored specifically for lightweight blow molded containers and rigid packaging applications, HHM 5502BN delivers an outstanding combination of high stiffness, exceptional processability, and excellent durability[cite: 14].

Key Features

• High Molecular Weight Ethylene-Hexene Copolymer providing superior structural integrity[cite: 14].
• Exceptional Processability with a melt index of 0.35 g/10min for stable blow molding parison control[cite: 14].
• Excellent Stiffness & Strength featuring a high flexural modulus of 1,370 MPa (200,000 psi) and tensile strength at yield of 27 MPa (4,000 psi)[cite: 14].
• High Durability with reliable Environmental Stress Cracking Resistance (ESCR Condition B, 100% Igepal $F_{50} = 24\text{ h}$)[cite: 14].
• Extreme Low-Temperature Resistance with a brittleness temperature below -75°C (<-103°F)[cite: 14].
• Regulatory Compliance: Meets ASTM D4976 - PE 235, FDA 21 CFR 177.1520(c) 3.2a (use conditions B through H), and is listed in the Drug Master File[cite: 14].
