Webster, who has worked in the plastics and coatings business for more than 30 years, has significantly improved the processing and stabilization of natural and pigmented thermoplastic polyesters. Thermoplastic polyesters are polymers — the stuff of plastics — that can be heated, cooled and reformed repeatedly without significant changes in their composition or properties.
Webster’s discoveries have lead to products — such as fibers, slit tapes, films and injection-mold articles — that are better able to withstand exposure to high temperatures and UV and gamma radiation.
He also has shown how the organic and inorganic pigments used to dye raw, unprocessed nylon can be enhanced without using environmentally unfriendly chromium premetallized dyes. Currently, this technology is used to color thermoplastic polyesters.
The American Chemical Society’s Industrial Innovation Awards recognize individuals and teams whose discoveries and inventions contribute to the commercial success of their companies and enhance our quality of life.
