Wire and cable coating compositions of PA6 / 66 copolymer base resins for improved processability and properties

摘要

Polyamide composition for use in forming a wire or cable coating composition. The polyamide composition comprises a polyamide 6/66 copolymer component formed from substantially randomly distributed caprolactam monomers and hexamethylene diamine monomers. The polyamide 6/66 copolymer component may form the entire polyamide composition, or alternatively, the polyamide composition may comprise an amount of polyamide 6 homopolymer blended with the polyamide 6/66 copolymer component. have. The composition also includes at least one UV reducing component incorporated into the polyamide composition due to the reduced crystallinity of one or more additives, such as the polyamide 6/66 copolymer component, and not only has desirable transmittance and haze properties, but also tensile at break It provides retention of physical properties such as strength and elongation at break.
