Typical uses for RT571 include bushings, spacers, structural parts and other applications that require parts to be fabricated from an extremely thick walled glass tube.

Norplex-Micarta, headquartered in Postville, Iowa, says that RT571 has excellent strength at elevated temperatures but has also been formulated to facilitate the production of thick walled tubes. This formulation is said to allow for walls to be up to two times the ID without checks and cracks.

RT571 can be manufactured in standard lengths of 914-1219 mm with inside diameters of 19-906 mm, outside diameters of 25.4-914 mm, and wall thickness of 3.18-50.8 mm.
