Polymetrix AG is a specialized Swiss engineering firm that designs, supplies, and commissions complete industrial plants for the thermal treatment of polymers and other bulk materials. Its core expertise lies in solid-state polycondensation (SSP) processes for both virgin PET (vPET) and recycled PET (rPET), as well as the treatment of polyamides, PBT, and additional polymers.
The company's technologies enable the production of high-quality materials suitable for food packaging applications, including direct food contact with up to 100% recycled content, and technical uses such as high-strength yarns for seatbelts, tires, and textiles. Polymetrix plants emphasize energy efficiency, high throughput, and scalability, with rPET systems capable of processing up to 50,000 metric tons or more annually.
Headquartered in Oberbüren, Switzerland, the company maintains a wholly-owned subsidiary in Beijing, China, and supports projects worldwide. It traces its roots to Bühler Group's polymer technology division, becoming independent as Polymetrix AG in 2015 following a carve-out. Current ownership consists of 80% held by Beijing Sanlian Hope Shin-Gosen Technical Service Co., Ltd. and 20% by Bühler AG, positioning it as a Sanlian-Bühler company.
As the global market leader in SSP technology with significant market shares in vPET and rPET systems, Polymetrix serves major producers in the polyester and polymer industries, delivering full engineering, procurement, construction management (EPCm), and after-sales services. Its solutions support the circular economy through advanced recycling technologies.
