5 Common Foams That Can Stop Your Buzz, Squeak, and Rattle 

Available in many different thicknesses, densities, and chemical compositions, die-cut foams and sponge rubbers are used in many automotive and industrial applications – from gasketing, cushioning, and sealing to vibration damping, sound absorption, and more.

JBC Technologies will not only help you identify the best foam or sponge rubber material to stop your buzz, squeak, or rattle, we can also help you identify the right pressure-sensitive adhesive and release liner, source the materials, and surface treat, laminate, slit, and die-cut your foam to the exact specifications needed for your application. 

Here is a breakdown of  five common foams used to eliminate BSR:

1. Silicone

This synthetic material has the highest cost but also the highest performance. Silicone is resistant to water, ultraviolet rays, and ozone. It has a 460 degree service temperature range with its minimum falling at negative 60 degrees Fahrenheit and its maximum at 400. This foam type has poor adhesive coating characteristics and a very low compression set.

 2. Neoprene/EPDM Blend (Ethylene Propylene Diene Monomer)

This synthetic rubber falls in the middle in terms of cost. The neoprene/EPDM blend is highly resistant to water, ultraviolet rays, acids, and ozone while it has low resistance to oil and petroleum-based fuels. It has a 350 degree service temperature range with its minimum falling at negative 65 degrees Fahrenheit and its maximum at 250. This blend has poor adhesive coating characteristics and a medium compression set.

 3. PVN (Polyvinyl Nitrile) 

This foam costs a moderate amount. PVN is resistant to fuel, oil, and acids and has effective shock absorption. It has a 220 degree service temperature range with its minimum falling at negative 40 degrees Fahrenheit and its maximum at 180. This foam type has excellent adhesive coating characteristics and low compression set.

4. XLPE (Cross-Linked Polyethylene)

This foam type is low in cost. XLPE is resistant to mildew, mold, rot, bacteria, and chemicals. It has a 200 degree service temperature range with its minimum falling at negative 40 degrees Fahrenheit and its maximum at 160. This foam has excellent adhesive coating characteristics and low compression set.

 5. PVC (Polyvinyl Chloride)

This foam type is very economical in terms of cost and is appropriate for general-purpose projects. PVC is highly resistant to weather, oxidation, and fungi. It has a 240 degree service temperature range with its minimum falling at negative 40 degrees Fahrenheit and its maximum at 200. PVC has excellent adhesive coating characteristics and very low compression set.
