Fabric Rods

 

FABRIC BASED THERMOSETTING SYNTHETIC RESIN (PHENOLIC) BONDED LAMINATED ROLLED & MOULDED RODS & TUBES
GRADE LPF - 2
COLOR These Rods are supplied in natural Brown Colour
DIAMETER Standard Range is 4.0mm to 150.0mm diameter, but on special requirement we can manufacture up to 300mm dia
LENGTH These Rods are supplied in straight standard length of 305mm (1'), 610 mm (2') or 1000 mm.
DESCRIPTION These Moulded Rods are composed of laminations of Phenolic Synthetic resins impregnated cotton Fabric into a convolute form, moulded in cylindrical Moulds under heat and pressure and then ground to size, buffed & varnished to semi Glossy finish. These Rods are with clean smooth free from surface defects such as voids, Blisters cracks etc.,
APPLICATION These Fiber Phenolic Rods are intended for Fabrications of Mechanical components such as spacers, washers, etc., it is not recommended for Primary insulation for Electrical application involving commercial power frequencies at voltage about 600 volts Material is resistant to dilute solutions of most acids. It is poor for using alkaline solutions, it remains unaffected by most organic solvents except acetone, which may soften the material.
MACHINERY These Rods are capable of being turned, drilled, tapped sawed and machined in all directions without showing any sign of cracking, splitting or otherwise impairing the serviceability of material.
