Laminated Tubing

Group of cryogenic g10 tubing
Paper phenolic tubing
g11 Laminated Tubing

CURRENT, INC. Laminated Tubing is made of thermosetting resins (Phenolic, Epoxy, Silicone or Melamine) combined with various base materials such as cellulose paper, woven cotton cloth or glass cloth. Convolutedly wound under high pressure and heat, the resulting product is a dense homogeneous material that can be machined, polished, painted and printed on. Laminated Tubing is easy to saw, drill, tap, thread, and punch with ordinary tools. The material has excellent electrical insulating qualities. It’s lighter, more durable and more economical than metal in many instances.

In the past decades, hundreds of applications for our tubing have been employed. The potential of new space age applications is even more exciting.

CURRENT, INC. Laminated Tubing is available in lengths from 36” to 48” depending on grade, diameters from 3/32” i.d. to 4.000” i.d.; wall thickness from .020” to 1.000” depending on diameter of the tube. Larger sizes quoted on request. Finishes include ground, polished, or painted based on requirements. Tolerances are to NEMA standards. For special tolerances, please contact our sales office.

Whatever you manufacture or assemble, there is an excellent chance that there is a Current Inc. product that will improve your product. We’ll quote at no charge, just send us your specs and/or blue prints.
