Protective linings in reactors and tanks fabricated with Halar® ECTFE, Solef® PVDF, Hyflon® PFA/MFA® and Algoflon® PTFE granulars, provide excellent resistance to extreme chemicals and temperatures.
Fluoropolymer lining systems are an alternative method to using specialty alloys such as stainless steel, titanium, Inconel® or Hastelloy® for corrosion control purposes. Significant cost savings can be achieved and a reliable system specified by appropriate selection and application of fluoropolymer lining systems.
Halar® ECTFE, Solef® PVDF, Hyflon® PFA/MFA®, and Algoflon® PTFE are used as continuous linings within FRP dual laminate or steel substrates. Extruded liners can be pulled into steel pipe or over-wrapped with FRP in a dual laminate construction.
Thicker linings provide much better protection against permeation and abrasion. These linings can be applied through rotomolding or transfer molding, as found in most pumps, valves and fittings, or through sheet lining. The latter process may be a loose liner as in many PTFE applications or may use adhesives to bind the fluoropolymer to a surface.
