Overview
Isolate It Sorbothane Vibration Isolation Circular Pad 50 Duro (.25″ Thick 2.25″ Dia.) – 8 Pack is a Sorbothane-based urethane solution designed for vibration isolation, impact absorption, and noise reduction. Constructed from rubber and Sorbothane-based urethane, each circular pad measures 2.25 inches in diameter and 0.25 inches thick. The set includes eight pads with an approximate total coverage of 33.52 square inches.
These circular pads are available in 30, 50, and 70 durometers, with softer durometers having lower weight load ratings. The 50 durometer version is specified for load ratings ranging from 120 to 270 pounds per disc. The material is described as a proprietary viscoelastic polymer that combines shock absorption, vibration isolation, vibration damping characteristics, and good memory. More details and specifications can be found through Sorbothane vibration isolation circular pads.
Material and Construction
The pads are manufactured from a unique urethane material formulated to resist cracking, drying, scratching, or marring surfaces. The Sorbothane surface is described as durable and designed to maintain structural integrity. As a viscoelastic polymer, the material combines shock absorption with vibration isolation and damping characteristics.
Each pad has a thickness of 0.25 inches and dimensions of 2.25 inches by 2.25 inches corresponding to its circular diameter. The unit count is eight pads per package. The material type is specified as rubber and Sorbothane-based urethane. Installation consists of positioning the circular pads and pressing them into place. Additional technical details are available via this vibration isolation solution.
Intended Uses and Applications
These pads are recommended for vibration isolation, non-skid support, impact absorption, noise reduction, and protecting various equipment from vibration and heat build-up. They can function as feet, stops, spacers, and protectors in different applications and industries. The product description also notes that vibration sheets can be applied whole or used inside speakers or equipment housings to provide sound insulation.
The products are described as isolating vibration caused by front-loading washing machines, speakers, and other products that give off vibration at any level. The circular format allows placement under equipment corners or between structural contact points where isolation is required. Additional configuration information can be reviewed through the 50 durometer circular pad set.
Performance Characteristics
The durometer rating measures the weight load amount, and the 50 durometer configuration is associated with medium hardness relative to the softer 30 and harder 70 options. The specified load rating of 120 to 270 pounds per disc provides guidance for weight distribution planning when used as equipment feet or isolators.
Top reviews commonly describe effective vibration reduction under audio equipment, garage door openers, rooftop AC condensers, turntables, and other devices that transmit structure-borne vibration. Repeated characteristics include noticeable reduction in vibration transfer, decreased audible hum or buzz, and isolation performance when properly positioned. Reviewers also frequently note that the material is pliable and naturally sticky, which can help maintain placement without additional adhesive.
Installation and Handling Considerations
Installation consists of positioning each pad and pressing it into place beneath or between surfaces requiring isolation. Because the material is naturally sticky on both sides, it may adhere firmly to surfaces once installed. Some users reference adding a thin barrier layer beneath the pads when surface finish preservation is a concern.
The pads compress under load, particularly in stacked configurations for heavier equipment. The non-skid characteristics support stable placement once weight is applied. For further product specifications and configuration options, see these Sorbothane-based vibration isolation pads.
