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, pulleys and silent gears.
