REVAC BM

Description

Developed and formulated by WSBL Ltd at our UK manufacturing facility, Revac ISBM is a vinyl sound barrier loaded with barium sulphate and calcium carbonate minerals. The product is free of lead, unrefined aromatic oils, and bitumen. Revac ISBM has excellent resistance to mineral oils, greases, and alkalis.

Revac ISBM is designed to improve the sound insulation of existing panels of metal, wood’ and plastics etc.

Revac barriers are particularly effective in overcoming coincidence dip resonance found in stiff, lightweight composites such as plywood sheets, hollow core panels, oil and gas pipework etc.

Revac ISBM is available in high and low-density, low-temperature and self-adhesive options and in nominal weights ranging from 2kg/m² up to 10kg/m².

General Product Information:
  • The Revac® ISBM range of flexible barriers includes heavy mass layers from 2kg/m2 to10kg/m2.
  • Lower density and thickness bias options available.
  • Higher flexibility, higher strength variants available.
  • Oil and gas products are also available which are designed to meet ML-V sound barrier specification detailed in ISO 15665 and SHELL DEP’s.
  • Various substrates can be applied to ISBM products during manufacture (Hessian – UV Top-coats – Adhesives – Foams etc)
Benefits:
  • Thermoplastic material, so fully recyclable dependent on customer end use application.
  • Easy to handle and install.
  • Easy to cut with a knife.
  • High acoustic insulation.
  • Extremely good flexibility compared to other heavily filled acoustic materials of similar thickness.
  • Cold and heat resistant (to temperatures detailed in material specific TDS).
  • High sound dampening on metallic surfaces.
  • Available in sheet or roll form, dependent upon customer requirements.
  • Self-Adhesive variants available.
  • Manufactured using same product recycled content.
  • Easy recycling of product at end of life due to the compatibility of plastics used in the construction.
