Polyurethane combines the best properties of both plastic and rubber. Its high resistance to abrasion and tear resistance, high tensile and elongation values, and low compression set. Polyurethane is naturally flexible and exhibits virtually unlimited flexural abilities.
The two basic formulations of urethane, ester and ether, have some critical differences. Water attacks ester-based urethane, causing a significant reduction in physical properties. Ether urethanes exhibit far superior hydrolytic stability, especially in humid environments. Ether-based materials also resist fungus growth better than ester-based materials.
UPC offers a variety of colors in five different durometer levels: 98, 95, 90, 85, and 70 shore A. Polyurethane tubing can be used with push-in or barbed fittings.
