In a V-Belt, tension member is the main load bearing component for power transmission. In K.K. Premium V-BELTS, Dipped Polyester Cord as a tension member is used. Polyester cord with suitable yarn construction for desired strength and yarn choice for its high initial modulus maintains low strength throughout the life of the belt. Specially treated adhesive activated Polyester Yarn is used for good static and dynamic adhesion.

The cushion rubber which encapsulates the cords, prevents chafing of adjacent cords and meeting the stringent requirements of dynamic adhesion, resistance to ageing and structural integrity.

The base (compression) Rubber Compound has been designed to undergo negligible permanent deformation under load and provides good dynamic properties and heat resistance besides sufficient rigidity.
