Kor-Pak is a Phenolic specialist, carrying various grades of  phenolic materials to accommodate numerous applications.  Common brand names that we carry include: Micarta Ryertex  Gatke Canvas Phenolic What are Phenolics, and what are their applications? Micarta became a brand name when it was developed by George Westinghouse in the early 1900's using phenolic resins.  Micarta is now used as the general brand name term for resin impregnated fibre compounds.  This material is made from phenolic resins used to impregnate paper and cotton fabric which are cured under pressure and high temperatures to produce laminates. Micarta industrial laminates are typically phenolic, epoxy, silicon-based thermoset materials reinforced with fiberglass, cotton, cloth, paper, carbon fiber, moly, teflon, and others.  Pressure and heat is applied to layers of laminations which yields a chemical reaction (polymerization) which turns the layers into high-pressure thermosetting industrial laminated plastic.  There are numerous commercial grades which industrial laminates are manufactured in. Where are Micarta/Phenolic Laminates used? The most popular application for Micarta/Phenolic Laminates is in high strength electrical insulation.  Micarta/Phenolic Laminates are used in power generating and distribution equipment, aerospace, electronic, marine, heavy equipment, steel, paper, and various other industries/applications.

DC Magnetic Coils 

Shunt & series wound, OEM and aftermarket, also able to supply obsolete coils for major product lines.

Electro-Hydraulic Thrusters

• Both Wet and Dry Available (EB and ED), ELDRO and ELHY available to accommodate desired torque range [caption id="attachment_4271" align="alignright" width="163"] Electro-hydraulic thrusters[/caption]
• AC or DC
• Special Options available (i.e. Kevlar Dust Boot, explosion proof, lowering valve, high-temp silicone fluid)

Brake Controllers: Our Lenze and  Braketronics Controllers are used in conjunction with our AC Thruster brakes and are operated with a heavy duty foot pedal to create constant torque.  These enclosed variable frequency drives can be used with both AC and DC power input and can be programmed with your desired acceleration/deceleration times which creates a smooth set and release which eliminates wear on the brake.  These systems are popular choices to replace air over hydraulic systems and we can furnish drop-in replacements for these braking systems in various AISE and non-AISE dimensi0ns (i.e. 14" and 18").
