Material Notes:
Terratek® SC 50 is a proprietary blend of wheat starch and polypropylene for injection molding applications. SC 50 contains 50% wheat starch by weight, however, a range of properties can be achieved by altering the starch to plastic ratio and by the inclusion or admission of other additives. Formulations containing anywhere from 30% to 65% starch are available upon request.Information provided by Green Dot Holdings.
