Two new renewably-sourced unsaturated polyester resins

Two new Envirez® renewably-sourced unsaturated polyester resins are now available from Ashland Composite Polymers, a business group of Ashland Performance Materials, a division of Ashland Inc. (NYSE: ASH). Envirez L 86300 resin for general laminating applications and Envirez 86400 INF resin for the infusion process combine Ashland’s bio-resin formulation technology with DuPont Tate & Lyle Bio Product’s Susterra1 propanediol to maximize both resin performance and bio content.

The low hazardous air pollutant (HAP), Envirez L 86300 resin is thixotropic and features excellent physical properties with high heat resistance and is user-friendly for spray-up or hand lay-up composite fabrication processes. Envirez 86400 INF resin also features excellent physical properties and high heat resistance but is specifically formulated to maximize wet-out in the infusion process.

“As demand for green products has increased, so has demand for Envirez resin. By incorporating Susterra propanediol, we are now able to expand the range of applications for Envirez resins and offer a sustainable material option to a larger portion of our customer base,” said Jud Smith, vice president, Ashland Performance Materials, general manager, Ashland Composite Polymers.

Both resins are available commercially through Ashland Composite Polymers and Ashland Distribution. 

Materials from recycled products and renewable sources are key components of the products in Ashland’s Envirez resin line. Developed for the manufacture of high quality composite parts, Envirez resins are the first step to sustainable composites. Additionally, building and construction products fabricated using Envirez resins may contribute to LEED (Leadership in Energy and Environmental Design) point credits as part of Material and Resource Credit 6 for using a rapidly-renewable resource under the U.S. Green Building Council’s guidelines.
