This flexible NSF-61 ester-based polyurethane tubing offers abrasion, radiation, impact, weathering and tear resistance. It has high tensile and elongation values and low compression set. It resists a wide range of temperatures from -95°F to 185°F. It does not contain plasticizer, reducing the risk of flow contamination or tube hardening. While it is made from nontoxic material meeting FDA requirements for use with wet and fatty foods, unlike ether-based polyurethane tubing
, this ester-based tubing faces significant reduction in its physical properties when in regular, prolonged contact with water, humidity or fungi. Polyurethane tubing can be heat sealed, coiled, fabricated or bonded. Although polyurethane is commonly used in fuel applications in the oil and gas industry, due to additives in today's gasoline and petroleum products, field testing should be performed.
