WILMINGTON, Del. (June 28) — DuPont Co. expects to begin production in 2007 of Hytrel specialty elastomers and other materials using bio-based materials.
The products will be targeted for automotive, electrical/electronic and other industrial markets.
Intermediates for Hytrel will be made from corn sugar instead of petroleum, using a patented and proprietary process. The new Hytrel offering is produced using a new DuPont polyol made with Bio-PDO. The renewably sourced Hytrel grades will be available in late 2007.
DuPont said the performance and processing characteristics of the renewably sourced Hytrel are as good as or better than those of current products made wholly from petrochemicals. Preliminary evaluations comparing the new Hytrel grades with current offerings show improvement in some properties, the company said.
In addition to replacing petrochemicals with renewable resources, making Bio-PDO uses about 40 percent less energy than its petrochemical-based counterpart, DuPont said. The new products will contribute to DuPont´s corporate goal of deriving 25 percent of revenue from non-depletable resources by 2010.
