Thermoformed plastics are being asked to take on more challenging and higher-value tasks in large, thin-walled parts. Thermoforming has begun to allow manufacturers to dispense with metal for such components and avoid more expensive processing methods such as injection molding and machining stock shapes.
As thermoforming has advanced in these more demanding applications, formers have sought out higher-performing resins. Traditionally, they have worked with polymers in the lower tier of the price-performance pyramid, such as polypropylene, ABS, PVC, and HDPE. The search for high-performance thermoformable plastics has led to the adoption of polycarbonate, nylon 6, ...
