John Wesley Hyatt, an American, was the first person to produce a useable polymer two years later. He named the product celluloid. The prime virtue of polymers is a high strength-to-weight ratio. Industrial-strength polymers surpass titanium in tensile strength. To add strength and improve flexibility, polymers are sometimes fortified with short-fiber a....
