An ABS material replaced the original plastic, which was prone to cracking and failure.
Calenders can also be applied to materials other than paper when a smooth, flat surface is desirable, such as cotton, linens, silks, and various man-made fabrics and polymers such as vinyl and ABS polymer sheets, and to a lesser extent HDPE, polypropylene and polystyrene.

They developed a unique diver delivery vehicle (the Subskimmer), and were important for introducing high quality plastics (e.g. ABS) into the manufacture of underwater breathing apparatus.
