Material Notes:
Highly resilient, with higher tensile elongation and impact strength than standard grades, NYCAST® CP is used applications requiring an extra degree of toughness. A copolymer of caprolactam and laurinlactam, NYCAST® CP was originally developed specifically for use in ball valve seats in the oil and gas industry.NYCAST®CP with its higher elongation, superior dimensional stability and safety yellow color has found itself a superior choice for wobbler box inserts and coupling boxes in the cold rolling steel industry and mandrels covers in paper tube manufacturing plants.Data provided by the manufacturer, Cast Nylons Limited.
