Eastman has announced a collaboration with NB Coatings to 'create a new solution for interior Class A painted surfaces with Treva engineering bioplastic'.

It says Treva offers a viable option for companies interested in creating sustainable, cost-effective products. When painted with NB Coatings paint systems, Treva can meet the demanding Class A surface requirements as specified by OEMs.

"Treva provides a biobased, sustainable alternative to polycarbonate, ABS and PC-ABS for interior automotive applications at a cost-neutral position," said Chris Scarazzo, Eastman automotive market segment leader. "Eastman's material innovations match what OEMs need to develop lasting parts with sustainable materials and help them achieve their goals for sustainable content and replacement of petroleum-based plastic."

Sourced from sustainably managed forests, Treva has biobased content of 42-46 percent, certified by the USDA's BioPreferred program. To continue reducing waste and maximizing resources, Treva benefits from carbon renewal technology, Eastman's proprietary recycling process that recycles waste plastic typically sent to landfills or found as litter in waterways.

Carbon renewal technology is a chemical recycling technology that diverts mixed waste plastics from the landfill and converts them to simple molecular components that are then reintroduced in the production of a variety of Eastman products, including Treva—without performance compromise, it is claimed.

In automotive applications, Eastman maintains that cellulose-based Treva exhibits high performance and reduced environmental impact. With 'optical and birefringence properties', it provides high clarity and superior strength and is suitable for applications such as human machine interface (HMI) lenses. Treva also withstands the challenges of automotive interiors, including high temperatures, humidity, UV, scratch/mar and general durability requirements. Treva has low VOC emissions, which is critical for interior parts. Its processing ease and excellent flow enable good dimensional stability and thin-wall designs for less material usage and lower weight.

"As an environmentally conscious coating provider, NB Coatings is excited to announce this paintability breakthrough in collaboration with Eastman," said Jesse Fritcher, NB Coatings vice president of technical. "Our trials with Treva found adhesion of our coating technologies to be comparable to, and in some cases better than, that achieved with traditional grades of PC-ABS, providing new sustainable options for automotive design engineers."
