EVONIK INDUSTRIES AG - Rebound effect of 73 percent
- Up to 90 percent lighter
- Stable properties from -40 to +40 °C
Essen/Marl, Germany. A new modification of Evonik's established polyamide elastomer VESTAMID® PEBA is now available. Drawing on expertise built up over four decades, the polyether block amide can now be foamed, making a density of 0.1 g/cm³possible. The resulting foam has a rebound resilience of 73 percent and does not change its property profile in either hot or cold conditions.
VESTAMID® PEBA was introduced to the market by Evonik more than 40 years ago. From the outset, it was distinguished by its excellent low-temperature impact strength, chemical resistance, high elasticity, and good recovery behavior. These properties are valued by leading sporting goods manufacturers for use in sports shoes. The development of the foam now allows even greater cushioning in sports shoe soles, while retaining all the other properties of the compact material. The rebound of VESTAMID® foam far exceeds that of all soft foams previously used in shoes. At the same time, it returns most of the energy absorbed. Its stiffness can be adjusted as required, and its low weight ensures high wearing comfort.
The properties of the foam allow it to be used not only in sports shoes, but also in the automotive sector, for example.
The rebound resilience of the novel foam made from the polyamide elastomer VESTAMID® PEBA far exceeds that of other flexible foams.
