Canadian General-Tower Ltd. has developed a calendered vinyl for auto interior use that contains bioplastics.
The company set out to replace oil-based plastics in vinyl sheet used to cover seats, dashes and door interiors, Patrick Diebel said at the International Conference on Biocomposites, held May 2-4 in Toronto. Diebel is vice president for advanced technology for the Cambridge, Ontario, firm.
The material had to meet auto specs, run on existing equipment and be financially viable.
CGT worked with Toyota Motor Corp. to develop CGT's branded Vehreo product. The fabric under the vinyl has about 55 percent recycled material from PET bottles. The layer meets tough standards for high shear during coating and for not sticking to equipment.
Up to 20 percent of the vinyl main layer is bioplastic. Vinyl accounts for half of the main layer and biological plasticizer is present at 10-35 percent. Surface coating is a protein that can replace a petroleum-derived thermoset.
