 Current Laminated Spacers and threaded standoffs made of thermosetting resins (phenolic, expoxy, silicone or melamine), convolutely wound under high pressure and heat with other appropriate materials, have proved themselves in a wide variety of contemporary applications. Their insulating properties, resistance to extreme temperatures, and light weight make them particularly desirable for use in electronic and electrical equipment. Resistance to compression, impact, vibration, corrosion, and moisture are further benefits; noise reduction is another. The material is easy to saw, drill, tap, thread, machine, polish, and punch with ordinary tools.
Although our standoffs and spacers are especially suited for use in electrical equipment, there are hundreds of other applications where their properties and characteristics will benefit product design. And save you money, too!
Current, Inc. manufactures and stocks a wide variety of types and sizes for immediate shipment. We will also custom-fabricate standoffs and spacers -- or modify stock items -- to meet your special requirements. Tight specs and close tolerances are no problem.
Whatever you manufacture or assemble, there's an excellent chance that there's a Current product that will improve your product and your profit picture. We'll quote at no obligation. Just send us your specs and/or blueprints. For further information, call (203) 469-1337, Fax (203) 467-8435, or e-mail us.

GRADE X
Fair machining qualities, high dielectric strength under relatively dry conditions. Made from phenolic resin with kraft paper.
GRADE XX
Suitable for usual electric applications. Good machinability, particularly threading qualities. Not as strong mechanically as grade X tubes but better in moisture resistance. Made from phenolic resin with absorbent paper.
GRADE XXX
Suitable for high humidity applications. Has minimum cold flow characteristics. Good machinability. Made from phenolic resin with absorbent paper.
GRADE C
A strong tough material for applications requiring high impact strength. Easily machined but leaves a rough edge. Not recommended for electrical uses. Made from cotton weighing 4 oz./sq.yd. and phenolic resin.
GRADE LE
Made from a cotton material weighing less than 4 oz./sq.yd. Suitable for electrical applications requiring greater toughness than Grade XX. Better in machining properties and appearance than grade C. Not recommended for electrical use over 600 volts.
