Conveyor Belts, Power Transmission Belt and Silent Gears
Pebax® Elastomers Offer Outstanding Energy Return for Optimal Power Transmission
Hysteresis is defined as the energy lost during a cyclic mechanical stress of a material and is a function of the modulus and the loss factor, tan ∂.
The tailored molecular microstructure of Pebax® resins contributes to lower hysteresis and tan ∂ when compared to other commonly used thermoplastic elastomers. The combination of this property (over a wide temperature range) as well as tremendous toughness, light weight and ease of processability make Pebax® resins powerful candidates for highly efficient power transmission belts.
Monolithic conveyor belts Pebax® Elastomer
Monolithic conveyor belts are made from a single material and are often used in manufacturing industries such as textile, food (meat, fruits, vegetables), wood, and more. A single large continuous piece of Pebax® material can be used for a high-performance mono-material conveyor belt. Pebax® elastomers cover a wide range of hardness and show high reliability in terms of energy loss, temperature resistance, wear and tear resistance and anti-static properties.
Power transmission belts with Pebax® Elastomer
A synchronous belt or timing belt, is a type of power transmission belt that is used to transfer rotational motion between two or more shafts in machinery and mechanical systems. Power transmission belts have usually a composite structure in which Pebax® Elastomers are the intermediate layer highly compatible with the fabric and the rubber layers. Pebax® Elastomers are the material of choice for multi-material power transmission belts thanks to their excellent processability, weldability, lightness (adapted for high speed) and low noise and vibrations.
