Actually, Arkema has been manufacturing high performance DURABLE bioplastics in LARGE quantities for the last 50 years! No one cared they were biobased until now. Check our Rilsan PA 11 at http://www.rilsan.com, and http://www.pebaxpowered.com.
Rilsan has been used for automotive fuel lines, oil and gas drilling applications, and other harsh condiitions applications that require 30 year life with superior fatigue resistance and strength! And Rilsan has 100% biobased content! The DuPont material will have 30-50%.
The Pebax product line has long been used in performance running shoes. In fact, Atomic and Scarpa ski boot manufacturers each recentl launched high perfomance ski boots using biobased Pebax.
Sustainability without compromise.
