Description

Sorbothane is a proprietary, viscoelastic polyurethane material renowned for its exceptional shock absorption and vibration damping properties. This unique polymer is engineered to convert mechanical energy into heat, providing superior isolation and protection for sensitive components. It is an essential material for engineers and designers across the aerospace, defense, electronics, and industrial manufacturing sectors seeking to mitigate noise, vibration, and harshness (NVH).

Application

• Vibration Isolation Mounts: Used in precision machinery, laboratory equipment, and medical devices to prevent vibration transmission.
• Shock Absorption Pads: Protects sensitive electronics, instrumentation, and athletic equipment from impact damage.
• Acoustic Damping: Applied in audio equipment, automotive panels, and industrial enclosures to reduce noise and reverberation.
• Gaskets and Seals: Provides sealing with damping in applications subject to movement or impact.
• Footwear and Orthotics: Utilized in high-performance insoles and prosthetic components for superior energy return and cushioning.
• Sports Equipment: Incorporated into grips, handles, and padding to enhance comfort and reduce fatigue.
• Aerospace and Defense: Isolates avionics, guidance systems, and other critical components from extreme G-forces and vibration.

Quality Control

Our Sorbothane materials are manufactured under strict process controls to ensure consistent performance in key parameters such as durometer (hardness), damping coefficient, and compression set. We provide Certificates of Conformance (CoC) with each batch, detailing its physical and mechanical properties. For custom formulations, comprehensive technical data sheets (TDS) outlining specific performance specifications are available.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from direct heat sources, open flames, and strong oxidizing agents. For long-term storage, protect from ozone and ultraviolet light exposure.
