DIMFAB 280 Pads

DIMFAB 280 is a low durometer elastomeric compound that meets the qualification requirements for Distributed Isolation Material (DIM) specified for use in US Navy submarines and surface ships. It is a proven solution where structure-borne noise, shock or vibration is a problem. These relatively inexpensive mounting pads are specifically designed to perform successfully in applications where DIM mounts are required. DIMFAB 280 is available in standard 18" x18" pads. A major feature of these pads is that they can be readily cut to any desired shape or size for easy installation in a wide variety of applications.

Some features and benefits of DIMFAB pads:

• Reduce structure-borne noise
• Reduce vibration
• Cushion shock
• Exhibit good drift resistance
• Withstand hostile environments
• Meet or exceed Naval specifications regarding environmental requirements including salt spray, temperature storage, oil immersion, ozone, etc.
• Easy installation

Some practical aspects and considerations when using DIMFAB pads:

• Easily cut with scissors or sharp knife for ease of installation
• Easily stacked for greater thicknesses (alternate rib direction at each layer, and add thin, 16 GA, steel plate every third layer - e.g. 6 layers has 1 steel plate)
• Retain resilience
• Long service life
• Mercury free
