Two types of polyethylene tubing—one linear low density formula and the other, a style co-extruded with EVA (ethylene vinyl acetate)—are offered. While both are made from non-toxic ingredients conforming to FDA standards, they offer different performance characteristics. Linear low density polyethylene tubing is a lightweight, flexible product suitable for a variety of uses due to its relatively low cost. It offers no transfer of odor to critical streams, good dielectric properties, and is chemically inert, forming a good barrier to gases, vapors, and moisture.
