Isolate It! Sorbothane vibration isolator sheets are versatile anti-vibration pads that can be used as feet, stops, spacers and protectors in many different applications. The unique Sorbothane ultra-soft urethane is a durable, resilient, polymer that provides outstanding vibration isolation and non-skid properties. Sorbothane isolators help absorb impact and noise and have excellent resistance to aging; they will not harden or crack over time. They feature a smooth, clean, black urethane surface. Use them on any audio and electronic equipment to prevent skipping and interference.
More is not better. A large lightly loaded sheet will have a high spring rate and will not deflect enough to provide good isolation. Over compression will lead to short service life. The proper compression range is 3 to 20 per cent depending on the "Shape Factor." Shape factor is the ratio of contact surface (one side) divided by perimeter area. Geometry matters. Small circular pieces and rings "bulge" better than squares and rectangles. "Bulgeability" makes for better isolation. Use many small discs rather than a few large rectangles for best vibration isolation performance. Thickness matters. The thicker the sheet the lower the natural frequency. You need a sheet at least one-inch thick to get your natural frequency down to 10 Hertz. (10 Hertz is your target natural frequency for a 900 RPM motor.) Use the natural tackiness of Sorbothane or apply adhesives to glue the Sorbothane to metal plates on both sides or consider a custom design with molded-in stud mounts.
This sheet is perfect for cutting to meet the needs of special applications or can be used whole. Can be cut with scissors or a sharp utility knife.
Caution: This product contains plasticizer which may cause minor discoloration to wood, plastic, composite and other materials following prolonged contact.

- Bulgeability" makes for better isolation. Use many small discs rather than a few large rectangles for best vibration isolation performance.
- Thickness matters. The thicker the sheet
- Do not "bolt through" your Sorbothane sheet. The bolt will carry the vibration to the base. Use the natural tackiness of Sorbothane
- Or apply adhesives to glue the Sorbothane to metal plates on both sides
- Or consider a custom design with molded-in stud mounts.
- Use vibration-rated connections. Where bolted connections are used
- Use high-quality (thread deforming) lock nuts or doubled jam nuts to prevent connections from vibrating loose.
- 10 Hertz is your target natural frequency for a 900 RPM motor.
- Over compression will lead to short service life. The proper compression range is 3 to 20 per cent depending on the "Shape Factor."
- Shape factor is the ratio of contact surface (one side) divided by perimeter area. See page 11 for calculation of shape factors.
