These formulations provide excellent chemical resistance, low moisture uptake, excellent dimensional stability, and high impact and wear resistance.

The hose manufacturer decided to explore other material options that would meet requirements such as excellent colorability, good surface appearance, high flow for optimal productivity, and of course, compliance with U.S. In addition to its excellent colorability and high flow, the Versalloy solution possessed a lower specific gravity and resulted in lower scrap rates compared to the competitive TPV, providing the opportunity to reduce system costs.

KEY CHARACTERISTICS • Smoke mitigation • Flame resistance • Passes -40° cold impact testing • Crush resistance • UV resistance • Suitable for CSA Teck 90 specification • Excellent tensile strength (2,910 psi) • Natural grades for easy colorability MARKETS & APPLICATIONS This LSFOH thermoplastic meets critical requirements for low-voltage, armored cable jackets. Offering excellent mechanical properties, the ECCOH 5981 UV formulation provides a durable material choice for Teck 90 cables used in demanding locations where safety is paramount.
