Suzorite

Suzorite® For structural vibration damping, improved mechanical properties and GF replacement

  • Structure-borne vibration damping through dissipation
  • Enhanced reinforcement (stiffness)
  • Improved dimensional stability
  • Reduced warpage
  • Partial GF replacement

Suzorite® phlogopite and muscovite micas are ideal solutions for applications requiring reinforcement and structure-borne vibration damping and where greater resistance to moisture, heat, light or chemicals is required. They can also be used for partial replacement of glass fiber in PA6 without affecting stiffness.

Vibration damping

Imerys phlogopite and muscovite micas are ideal for improving vibration damping in polypropylene (PP) compounds, latex interpenetrating polymer networks (LIPN) and as a replacement of glass fiber in polyamide 6.6 (PA6.6).

Highly lamellar Suzorite® micas generate sound damping performance comparable to, or exceeding, glass fiber and in all cases superior to those of the virgin resin.

Suzorite® is ideal for improving noise reduction 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 damping coatings for trains, boats, buses, airplanes, cars and many other applications.

Reinforcement

High aspect ratio Suzorite® micas are also ideal for improving mechanical properties of plastic composites, including:

  • Flexural modulus and strength
  • Heat deflection (HDT) performance
  • Tensile strength

It also improves cross-flow shrinkage and shrinkage isotropy

GF replacement

High aspect ratio Suzorite® 150S and Suzorite® 325 HK micas and their surface treated counterparts Suzorite® 150 PO and Suzorite® 350 PO can significantly improve reinforcement in polyamides.

Their reinforcement in Polyamide 6 (PA6) is comparable to chopped glass fiber, so they can be used for partial replacement of glass fiber in PA6 without affecting stiffness.
