Marlex® Polyethylene Products

CPChem’s high‑density polyethylene (HDPE) resins are engineered for demanding applications such as pressure pipe, blow‑molded containers, geomembranes, and industrial packaging. Our HDPE delivers an optimal balance of stiffness, environmental stress crack resistance (ESCR), pressure performance, durability, and processability—backed by decades of polyethylene expertise and responsive technical support.

CPChem’s Marlex^® medium‑density polyethylene (MDPE) resins provide a reliable balance of toughness and flexibility for applications including pressure pipe, gas distribution, shrink film, and packaging. Designed for sustained stress and environmental exposure, Marlex^® MDPE offers excellent ESCR, impact strength, and consistent long‑term performance.

CPChem’s low‑density polyethylene (LDPE) resins offer versatility, clarity, toughness, and sealability for films, coatings, laminations, and flexible packaging. Supported by advanced technology and more than seven decades of expertise, our LDPE delivers consistent quality and dependable processing performance.

CPChem’s linear low‑density polyethylene (LLDPE) combines strength and flexibility for demanding packaging applications, including stretch and shrink films, heavy‑duty sacks, and liners. Our resins provide excellent toughness, puncture resistance, and sealing performance for high‑volume, high‑efficiency operations.

CPChem’s metallocene LLDPE (mLLDPE) delivers exceptional toughness, clarity, and sealing performance for high‑demand film and packaging applications. Enabled by advanced catalyst technology, our resins support precision, efficiency, and consistent quality for applications requiring superior strength and aesthetics.
