DuPont this morning announced an expanded slate of renewably sourced polymers that will contribute to the company’s goal of doubling revenues from sustainable resources to at least $8 billion by 2015. Chief among the new offerings are Sorona EP thermoplastic resins, Hytrel RS thermoplastic elastomers, Biomax RS packaging resins and Selarâ VP breathable films. A key ingredient in Sorona EP is Bio-PDO, which is made at the recently inaugurated DuPont Tate & Lyle Bio Products facility in Loudon, TN. Bio-PDO replaces petrochemical based 1,3 propanediol (PDO) and/or 1,4-butanediol (BDO) in two glass-reinforced grades of Sorona EP that will initially be available. Sorona EP is compared to polybutylene terephthalate (PBT). Sampling is under way with broader availability expected in 2008. No disclosure was made on beta sites where the material is being tested.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
