Inside Our Manufacturing: PVOH at Kuraray America’s Bayport Plant

Located in Pasadena, Texas, the Bayport Plant manufactures KURARAY POVAL™ and EXCEVAL™ polyvinyl alcohol (PVOH) resins, materials that play a role in more aspects of everyday life than many people might realize. These materials become ingredients in products varying from adhesives, paper coatings, textiles, packaging materials, and specialty films.

Bayport is one of the newer plants in Kuraray America’s manufacturing footprint, beginning operations in 2016. Together with the nearby La Porte Plant, Bayport operates as part of one integrated PVOH business serving customers across several continents, including North America, South America, Asia, and Europe.

How the product is made

Vinyl acetate monomer (VAM) is transformed into polyvinyl alcohol (PVOH) through a carefully controlled manufacturing process. Process materials are recovered and reused where practical. The finished product is then dried, milled to customer specifications, and prepared for shipment.

Throughout production, employees and contractors follow established procedures designed to keep the process consistent and safe. That same attention carries into the site’s regular safety walkthroughs, where leadership, operators, and third-party personnel review process areas together, identify potential hazards and address findings as quickly as practical.

Grade 49-88, used mainly in adhesives, is packed in 20-kilogram bags, 50 to a one-ton pallet, or in bulk bags of 500, 900, or 1,000 kilograms, and every pallet of PVOH leaves Bayport by truck.

Because PVOH dissolves in water, the packaging line keeps the resin enclosed from the silo through the augers to the sealed bag, with minimal exposure to open air. Each bag is tied, capped, and shrink-wrapped before it goes to staging.

Warehouse manager, Dorsey Williams, who joined at startup and celebrated ten years with the company in September 2026, often encounters the most common assumption visitors bring with them.

Built for flexibility across Kuraray’s network

Bayport was designed using proven manufacturing practices and operational experience from across Kuraray’s global network

Grade 49-88 was once imported, where longer lead times could impact on-time delivery. Bayport is now the Kuraray Group’s largest producer of that grade and ships directly to customers from its own warehouse, shortening delivery during a hurricane-season rush or when a customer brings a new line online.

Quality Built into the Process

At Bayport, quality is integrated throughout the manufacturing process. Checks are performed at key stages of production, well before the finished product is prepared for customers.

Cory Witt, Supervisor of Quality Control for PVOH, oversees the site’s QC laboratory and a team of ten. Witt has been with KAI for five years and supports the systems and testing processes used to verify that products meet established quality requirements.

One of the lab’s most important checks is also directly tied to what customers need from PVOH: its solubility in water.

Samples are prepared and tested against the dissolution requirements for each grade. If a product falls outside specification, it is blocked from shipment while the team determines what happened and what needs to happen next

That approach extends beyond the laboratory.

Bayport operates under ISO* 9001, ISO 14001, RC** 14001  and ISCC*** PLUS certifications. For Witt, RC 14001 has one of the strongest day-to-day influences because of how closely it connects to health, safety, and environmental management across the site, helping keep those priorities embedded in how work is planned and carried out.

The standard helped bring a more structured approach to Root Cause Failure Analysis (RCFA), giving teams a consistent way to trace a problem back to its source, determine why it happened, and identify corrective actions. It also strengthened the process for handling products or processes that do not meet requirements.

*ISO – International Organization for Standardization; **RC – Responsible Care®; ***ISCC – International Sustainability & Carbon Certification

Audits put those systems to the test. Auditors review the site’s documentation and processes, but they also spend time with the people doing the work to make sure procedures are understood and followed in practice.

That connection between established procedures, consistent execution, and safe operations was recognized in 2026 when Bayport received the Dr. Mannan Award for Zero Process Safety Incidents from the Texas Chemistry Council and Texas Chemistry Alliance.

For Witt, the reason those standards matter is straightforward: “Standards matter here because Kuraray and our customers matter.”

Automation ‘designed-in’ from day one

As Bayport was developed, the PVOH business had the opportunity to draw on learnings from Kuraray’s Singapore operations, evaluate available technologies, and intentionally integrate them into the plant’s processes.

This included robotic arms, bulk bag machines, and conveyors with programmable photo eyes for final packaging. Today, operations also use GoPlant for operator checklists and rounds and are exploring the use of artificial intelligence to support predictive maintenance.

Ten years of building experience

As the plant marks its 10th anniversary in 2026, its story goes back to the workforce assembled for startup in 2016, a team of people who had never worked together before. People came from oil and gas, the EVAL business unit, PVOH manufacturing elsewhere, and expatriates from Singapore and Japan serving three- to five-year assignments, with three expatriates still on-site today.

New employees complete internal training on ISO 9001 and Responsible Care®, learn what each standard requires and how their job fits within it, and are then tested on the standard operating procedures for the role. The standards have given the plant its training programs and detailed procedures, and they keep institutional knowledge written down rather than in people's memories.

That knowledge transfer is also part of how the Bayport team approaches its culture. As Plant Manager Raymond Myska explained,

"Bayport has always promoted internal candidates," Williams said. "A lot of the folks that started here with me ten years ago are still here today, not only in the same role, but have excelled to various positions within the company."

Ten years after startup, that continuity matters. The people who helped build Bayport’s processes, standards, and culture are now carrying that experience forward, helping train the next generation of employees and supporting the plant as it continues to grow.
