The Most Advanced Material for Sponsons and Inflatable Boats

Wing polyurethane has twice the puncture resistance and four times greater abrasion resistance than Hypalon. The expected service life of a polyurethane tube is 7-8 years versus only five for a Hypalon tube.

*2011 Industry Testing
performed using current generation CRRC industry standard polyurethane vs. hypalon fabrics
Testing done in compliance with NAVSEA T9008-CV-SBS-010: Specification for Building Combat Rubber Raiding Craft. ASTM test methods include D413, D751, M5306.

Navy Testing Concludes:
“40 oz/yd Urethane... is CONSIDERABLY STRONGER than the 40 oz/yd Hypalon 1993 Carderock Division Testing Results”
"Tubes constructed of polyurethane coated fabric exhibit better key physical properties than tubes constructed of Hypalon coated fabric...better tensile strength, tearing strength, puncture resistance, coating adhesion, and abrasion resistance.” 2001 Lori L. Fanney, Dept. of the Navy Memorandum
