In Tennessee, Eastman Chemical has launched a new cellulose-based engineering bioplastic dubbed TRĒVA.
Made up of about 50% cellulose, TRĒVA provides chemical resistance to skin oils, sunscreens and household cleaners. Its low birefringence also eliminates the “unwelcomed rainbow effect” that some plastics demonstrate with polarizing light, Eastman says.
Applications include eyeglass frames, wearable electronics, headphones; electronic display applications, such as lenses and covers, that consumers need to see through; electronics, housings, intricate cosmetics cases, and other products with high design and complex specifications; and automotive interior components. TRĒVA is also BPA- and phthalate-free.
