PHENOLIC LAMINATED PAPER BASE tubing,
precision paper tube,impregnated tubing selectioned types of supports
(pure cellulose kraft paper, cotton fabric, glass fabric and glass
matterial ,phenolic paper PFCP ,phenolic paper,PHENOLIC LAMINATED
PAPER BASE ) which are impregnated with various types of resins
(phenolic, epoxy, melamine, silicone and polyester), obtaining pre-preg
products, and utilising modern facilities, manufactures a wide range
of laminates and tubes and rings for direct selling to its customers.it
has superior high temperature, high dielectric and good mechanical
qualities. Precision Paper Tube Company has developed a method of
fabricating square, round, or rectangular tubing of this material
using a special, compatible binder that provides a laminated, thermally
stable, Class "H" insulating tubing.
Besides that, through the cooperation with third companies equipped
on purpose in this field, can supply any type of CNC machined parts
also with metallic inserts.
Advantages: Its is recognized for its excellent electrical, thermal and mechanical properties. Precision has developed a method of fabricating this tubing using a compatible binder that provides a laminated, thermally stable, Class "H" insulating tubing that can be used in flame retardant applications.
Suggested Uses: Transformer forms and collar supports; voltage regulator transformers; primary coil forms; as bobbins in high temperature, continuous run motors; motor shaft insulators and spacers for industrial type, heavy duty tools; high temperature potting cases; heat insulators and shields; flame proofing applications.
