Abstract
An article of manufacture which has a high resistance to chemicals, solvents, and heat formed from a blend of (A) a polyamide, such as polycaprolactam; (B) a functionalized polyethylene, such as low density polyethylene; and (C) an unfunctionalized low density polyethylene. The blend has a melt viscosity suitable for extrusion into convoluted tubing, nonconvoluted tubing, sheets, films, and the like.
