Advantages of Rubber Over Metallic

ADVANTAGES OF USING RUBBER OVER METALLIC

Rubber vs. Metallic Expansion Joints

There are many advantages of using rubber over metallic when it comes to expansion joints. It is increasingly important to evaluate what materials will best work for your specific application. Although Holz Rubber supplies metallic expansion joints, our helpful team will always evaluate your specific application to determine if metallic or rubber is better suited. Simply contact us via our Contact page with the details of your specific application and one of our team members will make a recommendation for you.

Below is a list of advantages of using rubber for your expansion joints.

  • Improved resistance and longer cycle life – Rubber joints can exceed 50,000 cycles vs. 2,000 cycles of metallic
  • No vibration fatigue – rubber joints act as a dampener
  • No danger from stress corrosion – metallic joints are subject to irregular cracks from stress and corrosion
  • Resistance to external damage
  • No corrosive electrolytic action – metallic requires costly gaskets
  • Shock resistance – rubber absorbs shock well
  • More flexible in less space
  • Simultaneous axial and lateral deflection
  • No internal sleeves necessary
  • Dampens noise
  • Choice of elastomers and fabric
  • Minimal face-to-face dimensions
  • Lightweight
  • Low movement force required
  • High resistance to abrasion or erosion

Acoustical impedance is defined as the product of material density times velocity of sound in that material. In acoustical systems, low impedance corresponds to low sound transmission. Relative impedance is based on Rubber
