NAT — Refers to natural polypropylene-base resin products. They are impact resistant, durable and have a high chemical resistivity. The standard color for any product ordered with this suffix is gray.
ALSO AVAILABLE IN Conductive (CAS) and Dissipative (BAS):
CAS — Refers to Bentron, a conductive polypropylene-base material. This material contains a carbon additive to provide an electrically conductive path through the material. Bentron has a surface resistivity of less than 105 ohms/sq. All products with this suffix are black in color. BAS — Refers to Benstat, Metro’s patented static dissipative polypropylene-base material. Benstat has a surface resistivity of more than 105 ohms/sq. and less than1012 ohms/sq. The standard color for any product with this suffix is blue.
