Benchmark’s anti vibration and shock isolation materials can be supplied in the form of sheets, cut pads, washers and bushings for OEM applications. The properties of our products are specifically designed for the reduction of impact shock, vibration isolation and structure-borne noise reduction.

Benchmark has worked with original equipment manufacturers in a variety of industries and applications where absorption of impact shock and isolation of transmitted vibration is desired.

e low frequency vibration isolation and reduction of impact shock.

VIBSORB nitrile pad has been used for years for mounting machinery and sensitive equipment where absorption of impact shock or isolation of transmitted vibration is desired. MIL C 882 pads may be bonded together (“layered”) to achieve the desired isolation efficiency for any application.

MIL C 882 material is available as isolation washers and OEM parts.


  • VIBSORB pad can withstand loads up to 300 psi.
  • VIBSORB pad can have a vertical natural frequency as low as 5.0 Hz and a horizontal natural frequency as low as 3.0 Hz.
  • VIBSORB pad has a high energy storage rate per unit volume which makes it ideal for certain shock isolation applications.


The unique “cell” (waffle) pattern on the MIL C 882 vibration isolation pad is specifically designed to maintain the proper shape factor for the pads when under load. This feature allows VIBSORB pads to support more load than other rubber pads of the same size and thickness.

Benchmark pads have a damping rate of 6% of critical.

BENCHMARK Vibration control pad is made from a nitrile compound and is therefore impervious to most oils and cutting fluids and is resistant to the effects of steam, water, mildew and brine. The effective temperature range is -20°F to 150°F.

VIBSORB A 25 psi 5/16″
VIBSORB B 50 psi 5/16″
VIBSORB C 100 psi 5/16″
VIBSORB D 200 psi 1/2″
VIBSORB E 300 psi 1/2″


What is shape factor?
Shape factor is a geometric measure (ratio) of surface area to the perimeter area allowed to expand laterally. Shape factor has an influence on the deflection and load limit properties of a material. Essentially rubber is an incompressible substance that deflects by changing shape rather than volume. The featured cell geometry on the surface of the VIBSORB  pads minimizes the shape factor usually associated with unreinforced, elastomeric (rubber) pad materials.

Does durometer affect the isolation efficiency of rubber pads?
Yes, durometer affects the isolation efficiency of rubber pads. The higher the durometer, the higher the stiffness. The stiffness of the spring (rubber pad) increases the natural frequency of the isolator, thus affecting the isolation efficiency.

How is damping different than isolation/absorption?
Please see Robert Haley’s paper on Isolation Theory, specifically pages 3 to 7.

Can VIBSORB pad work as a shock isolator/damper?
Yes, VIBSORB pad works as a shock isolator/damper by the dissipation of the kinetic energy (KE) generated by the shock event.

Can VIBSORB  pad be cut to size in the field?
VIBSORB pad can be cut using scissors or a fine tooth saw blade. Holes can be cut using a fine tooth, narrow angle hole saw.

What adhesive is recommended to bond VIBSORB to steel?
Benchmark Epoxy adhesive is recommended to bond VIBSORB to steel. The steel surface should be sandblasted and the VIBSORB pad buffed or abraded.

What is the temperature range for VIBSORB material?
The temperature range for VIBSORB material is -40° to 200° F.
