HY-T® Plus improved materials are the key to its durability and versatility. Whether you are talking about rubber belts or metal chains, most materials will elongate when put to use. The secret to reliable performance is not to eliminate elongation, but to control it so that it is minimal, predictable and uniform. To achieve these criteria, we developed the Vytacord® tensile member. Vytacord® provides the high-strength, high-horsepower rating capacity needed to effectively transmit today’s drive power. It is even tough enough to tolerate slight sheave misalignment that would quickly destroy ordinary belts. The Vytacord® tensile member provides dimensional stability. As a result, each belt of a given size will maintain its length consistency, no matter when or where it was produced. The exceptional dimensional stability properties of HY-T® Plus eliminates matching problems, improves performance and increases service life. Our engineered heat- and oil-resistant rubber compound is used in both the cushion and insulation sections of HY-T® Plus. Belt construction provides the flexibility on small pulleys. As a result the belt is able to serve a dual purpose for both Classical and FHP, while offering more versatility than any other Classical belt.
