Floating Roof Seals

TCI manufacturers state-of-the-art PTFE/fiberglass composites and 100% PTFE CrossFilm™ materials for floating roof seal manufacturing companies. Applications where TCI’s materials are used include vapor barriers and seals, coverings, wipers, wiper tips, leg socks, bladders, gauge pole sleeves, tubes, strut coverings, tank linings, and geomembrane liners. All floating roof seal materials and products are unaffected by exposure to UV and contain anti-static properties.

TCI’s unique all-PTFE CrossFilm™ material solutions allow for guaranteed corrosion-free performance and long-term non-flammability retention, regardless of the chemicals within the tank.  CrossFilm™ materials also have superior flexing properties, maintained non-porosity traits, and minimized permeation levels compared to fiberglass-reinforced materials.

Because elastomeric products are chemically susceptible and degraded by UV, the floating roof seal industry has advanced to using PTFE-based materials for long-term success in floating roof seal applications.
