What BAYSTAR does

Baystar (legally Bayport Polymers LLC) is a North American polyethylene resin manufacturer formed in 2018 as a 50-50 joint venture between TotalEnergies Petrochemicals & Refining USA, Inc. and Borealis AG through the Novealis holding entity. The company is headquartered in Pasadena, Texas, where it operates three polyethylene production units (Bay 1, Bay 2, and Bay 3), and a 1 million metric-ton-per-year ethane cracker in Port Arthur, Texas, that supplies integrated ethylene feedstock. The cracker was commissioned in July 2022 and Bay 3 — the first Borstar technology unit in North America — was commissioned in October 2023 behind more than $1.4 billion of investment, more than doubling Baystar's nameplate capacity to approximately 2.2 billion pounds of polyethylene per year. Senior leadership comprises polyolefin veterans from Borealis, Borouge, TotalEnergies, ExxonMobil, Chevron Phillips, and Westlake. The company is governed under shared 50-50 control by its two parents, with a board drawn from each side, and currently employs 101–250 people.

Baystar's product and technology platform is anchored on two licensed proprietary technologies: Borstar 3G multi-modal polyethylene technology from Borealis, which employs a two-loop-reactor/gas-phase-reactor architecture with a proprietary catalyst enabling broad molecular weight and composition distribution, PFAS-free formulations, and incorporation of more than 50% post-consumer recycled content; and Lumicene second-generation metallocene catalyst technology from TotalEnergies, producing E-Hexene copolymers that combine narrow molecular weight distribution with long-chain branching for high processability, mechanical strength, and optical clarity. The resulting portfolio spans HDPE and MDPE film grades (HDPE 1285/2285/4903; Borstar FB2230, FB1350), Lumicene metallocene film/fiber grades (M2504EP, M2710, M3410, M6410, FG850, FG950), rotomolding grades (M3581UV, M4041UV), blow molding grades (HDPE 5502, 6508, 50100.1/2; Borstar BB2588; B5845; SB1359NA; Lumicene BM359SG), and pipe/profile grades (HDPE 4920N, CD4625, CD471, CD492, WM4930, WM5001) carrying PE4710, PE100, NSF/ANSI 14/61, AASHTO M294, and ASTM F2160 certifications.

Baystar operates a B2B direct sales model serving four primary use-case segments — film manufacturers, blow molding manufacturers, pipe and infrastructure, and rotomolding and specialty converters — across North America. Revenue is generated through transaction-based resin pellet sales, bundled with technical services, joint product development, and supply-chain collaboration. Pricing is quote-based and negotiated directly with each customer rather than published; the company emphasizes relationship-driven service and "person-to-person" commercial engagement as a deliberate point of differentiation versus large commodity petrochemical peers (ExxonMobil, Dow, LyondellBasell, Chevron Phillips). GTM includes dedicated customer service representatives, technical sales collaboration, and participation in industry events such as NPE 2024, where Baystar hosted customer lounges for delegates from 131 countries.

Core offering

Baystar manufactures and sells customized polyethylene (PE) resins — including HDPE, MDPE, and specialty metallocene grades — to converters and manufacturers across North America. The portfolio is built on two proprietary technology platforms: Borealis Borstar 3G (multimodal) and TotalEnergies Lumicene (metallocene), enabling products for film, blow molding, rotomolding, pipe, and specialty fiber applications. The company operates as a fully integrated producer with its own ethane cracker in Port Arthur, TX feeding three PE units in Pasadena, TX.

Product overview

Baystar is a polyethylene resin manufacturer offering a broad portfolio of HDPE, MDPE, and metallocene-based PE products serving film, blow molding, rotomolding, pipe, and fiber applications.
