Sound Damping

Sound Damping Imerys micas – your ideal solution for structural vibration damping

Many types of minerals can be used to achieve heat dissipation but mica remains the most efficient of all. In tests, selected grades of mica at different loadings generate vibration damping properties comparable to, or exceeding, glass fiber.


Imerys micas are ideal for improving vibration damping in polymeric compounds for:  

  • Power tool housings
  • Under-the-hood automotive parts
  • Bitumen membranes for use in automotive and domestic appliances 
  • Water-based structural vibration sound damping coatings for trains, boats, buses, airplanes, cars and many other applications.

 In most cases, sound damping is not the only property desired from a polymer based composite, it is therefore important to note that mica can also provide other benefits, namely:

  • Increased flexural modulus and strength
  • Improved heat deflection (HDT) performance
  • Increased tensile strength
  • Improved impact properties 
  • Demonstrable cost advantages
  • Decorative effects
