A process developed at Johnson Controls' Plastics Technology and Automotive Systems Groups allows polyethylene terephthalate (PET) resin to be recycled from cola bottles and reprocessed into car seat pads. The seat backs and cushions use recycled PET fibers from soft drink bottles. PET seat pads offer several advantages over conventional polyurethane foam pads, including lighter weight, better breathability, and easier molding into a wider variety of densities. PET seat pads also recycle more easily than foam pads. Johnson's thermobonded PET manufacturing process uses heat and low pressure to compress the fiber into seat pads. The process eliminates adhesives and their associated solvents, and is less environmentally toxic than foam blowing methods.
