Polyethylene-lined EVA tubing is a co-extruded tubing that combines the functionality of polyethylene with the flexibility of EVA (ethylene vinyl acetate), and is used in applications such as food and beverage processing, pharmaceutical uses, chemical transfer, appliances, computer equipment, laboratories, fluid feeds and drains and more. Polyethylene tubing is typically a semi-rigid product. The addition of EVA gives it enhanced flexibility and allows its use with economical barb-style fittings. The tubing’s patented manufacturing method ensures a permanent bond between the inner and outer layers. First the core of low-density polyethylene is extruded, then farther down the production line, the EVA covering is extruded around the core using a patented process. The result is a tubing that offers different performance characteristics for the inside and outside of the tube — cleanliness inside, flexibility outside.
