Features and Benefits
  • Extraordinary strength retention and superior flex properties in corrosive and demanding environments.
  • Gas tight film barrier properties.
  • Reliability & low maintenance costs.
  • Ability for the product to be fixed/repaired on site
  • Chemical resistance.
  • Corrosion resistance.
  • High-temperature resistance.
  • Crack-free surface provides corrosion resistance against aggressive chemicals.
  • Fiberglass fabric can withstand chemical attack, high temperatures, and vibration – all while compensating for misalignment and movement in ducting.
  • With a multi-layer construction, they are void and pinhole-free, optimising the cost/benefit trade-off relating to barrier properties.
  • Compliance includes 2002/95/EC RoHS I, 2011/65/EU RoHS II & 2015/863/EU RoHS III.
Applications
Flue gas desulphurisation in power plants
The composite materials contribute to the efficient removal of sulphur dioxide emissions from industrial flue gases by providing flexible product for use in expansion joints.
Chemical Storage:
Ensures the safe and secure containment of chemicals while protecting against corrosion, leaks, temperature fluctuations, and fire hazards.
Gas turbine systems
High-strength woven fiberglass substrates provide thermal insulation, fire resistance, noise reduction, corrosion resistance, structural reinforcement, and electrical insulation. Their versatility and customisable properties make them valuable components for improving the performance, durability, and safety of gas turbine systems across various industries.
Petrochemical industry
The ability to withstand extreme conditions, resist corrosion, provide insulation, and offer acoustic control makes Versiv Environmental Composites valuable assets in chemical processing plants, refineries, and other petrochemical facilities.
KEY TAKEAWAYS
Used in expansion joints for flue gas desulphurisation and power plants; and in petrochemical storage systems, Versiv Environmental Composites are a high-strength materials and possesses superb mechanical strength and flexibility.
Rigorous testing standards
Versiv develops custom application testing based on each of our partner’s product uses in order to create the best possible solution. Some tests that are included but are not limited to environmental, durability, and reliability testing to give you peace of mind making sure that products work in the hardest environments. Our testing begins during the co-development process to develop relevant tests and gather data that allows us to create market-ready solutions quickly.
Some of our tests:
  • FTMS 191A-5041

  • FTMS 191A-5030

  • FTMS 191A-5102

  • FTMS 191A-5136

  • ASTM D149-81
