Product Name: Insualting Paper tube
Product Description
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.
Minimum Wall Thickness:>1.4mm
It is created from KH550 glass cloth with alkali-free that has been
impregnated with polyamide resin under pressure. heat and rolling. The thermal
grade is class h insulation. With excellent electrical. Physical and mechanical
property, thermal-resistant, radiation-proof. Used for the insulating slots.
