Monadnock Non-Wovens LLC (MNW, Mt. Pocono, Pa., U.S.) is introducing HTAC Veil, a new generation of veils used in the corrosion barrier of fiberglass-reinforced plastic (GFRP) equipment. MNW designed and developed the binder-free HTAC-apertured veil using meltblown ethylene chlorotrifluoroethylene (ECTFE) fluoropolymer resin.

The provides benefits such as high chemical and abrasion resistance at high temperatures and excellent fire retardancy (it maintains a flame spread index of zero per ASTM E-84). According to the company, the material also significantly extends the performance, integrity and life of GFRP tanks, tankers, scrubbers, pipes, ducts and stacks. 

HTAC Veil has a high resistance against strong acids, sodium hydroxide, sodium hypochlorite, chlorine dioxide and solvents. With a high permeation resistance, it also reduces blistering in hot concentrated hydrochloric acid. It has an apertured hole pattern of IPS-10 and is easy to inspect in a 100 mils GFRP corrosion barrier.

As with all MNW products, HTAC is manufactured with renewable electricity.
