What are dual laminates?

A Dual Laminate is a cost effective, long-term solution to corrosive and abrasive environments. Industries requiring corrosion resistant equipment are increasingly recognizing the need for the improved service life that these products provide. Lost production time due to equipment failure can be greatly reduced with dual laminates. Dual laminate construction combines the primary corrosion barrier of a thermoplastic lining with the structural advantages of FRP. These products are used when operational service requirements exceed the limits of straight FRP and when cost considerations prevent the use of costly high-nickel alloys. Low maintenance and design flexibility ensure that dual laminates are the preferred choice for harsh environment applications.

Types of thermoplastic linings include:

  • PVDF (Kynar)*
  • PVC (Poly vinyl chloride)
  • ECTFE (Halar)*
  • PP (Polypropylene)*
  • HDPE (High Density Polyethylene)*
  • FEP (Teflon)*
  • MFA (Hyflon)
  • CPVC (Chlorinated Polyvinyl Chloride)*
  • PFA (Teflon)*
  • *CFI can produce
