Nycast CP

About
Highly resilient, with higher tensile elongation and impact strength than standard grades, NYCAST CP has proven itself in many 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. This durable material provides an economical, high-performance bridge between NYCAST 6 and NYCAST 12 formulations. 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 as well as mandrels covers used in paper tube manufacturing plants. High impact resistance High tensile elongation Reduced water absorption Lower hardness Easy to machine&&
