High-density polyethylene (HDPE)
polymerHigh-density polyethylene (HDPE) is a semi-crystalline thermoplastic polymer characterized by a linear molecular structure and higher density compared to other polyethylene grades, giving it greater stiffness and strength. It is widely used in packaging films, rigid containers, piping systems, and automotive components across consumer, industrial, and infrastructure sectors, where its combination of chemical resistance, processability, and cost-effectiveness make it a preferred choice over lower-density polyethylenes and competing commodities plastics.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
