Dual Laminate
Dual laminate piping and equipment are used in certain operating and environmental conditions where FRP (fiberglass reinforced plastic) composite material alone is insufficient. This method introduces thermoplastic material as the chemical resistant liner and thermoset FRP material as the structure. The excellent corrosion resistance of the thermoplastic, coupled with the strength of the FRP, produce a finished product that stands up to higher combined service temperatures and pressures than either could on their own.
Please contact the Chemposite engineering department for more information on our Dual Laminate Products.
