HPP Cloth-Glass Silicone Tape
HPP HP27965-8R and HP27975-8R are manufactured from silicone rubber/fiberglass cloth backing coated with high-temperature backing. HP27965 and HP27975 are used in the plasma spray process.
HPP HPH7525 and HPH7575 (HVOF) are heavy-duty pressure-sensitive tapes used for thermal spray masking. They are manufactured by combining multiple layers of silicone rubber, aluminum foil and fiberglass coated with aggressive high-temperature silicone adhesive. HPH7525 and HPH7575 are used as high-temperature masking tapes in thermal spray and high velocity oxygenated fuel processes.
The aerospace industry is the prime market for the use of plasma spray tapes, specifically jet engine manufacturers, overhaul centers, major airline maintenance centers, Air Force Bases, and Naval Air Rework Facilities.
