Chemical Resistant, Corrosion Resistant, Good Reactivity

Duro-Bond PFA lined equipment is used in many ultra-high purity applications in the semiconductor, pharmaceutical, and chemical industries. The outstanding corrosion protection provided by Duro-Bond PFA broadens equipment service capabilities and extends its useful life. Its superior chemical resistance, together with its excellent adhesive bonding characteristics, makes Duro-Bond PFA a high performance lining material for almost any corrosive or high purity application.

Thermal decomposition - PFA starts to decompose at 260°C; Hazardous decomposition products - Gaseous fluorinated hydrocarbons (fluoro-olefins, carbonyl fluoride and hydrogen fluoride). Scrap PFA must not be incinerated.; Hazardous reactions - Traces of COF2 are evident at around 350°C.; Transportation classifications - PFA is not classified as a hazardous material. No special precautions or procedures need be followed to transport PFA resin or sheet lining.

PFA resins are nonvolatile and safe at normal room temperatures. Good safety practice requires the use of adequate ventilation and respirators when processing PFA. Heating PFA may produce fumes and gasses that are irritating or toxic. Care must be taken to avoid contamination of smoking tobacco or cigarettes.

All lined surfaces are visually inspected for surface defects. Any special dimensional tolerances required after lining are also checked.. All lined areas are then spark tested for pinhole leaks using a dielectric spark tester adjusted to 10,000 volts. The tester is moved constantly and quickly over the lining surface to prevent a burn through.
