Phenolic's corrosion resistant capacity makes it appropriate for applications in industries where corrosive materials are in prevalent usage.  The chemical processing and pulp and paper industries, for instance, use Phenolic extensively for tank liners, rollers and gaskets as well as myriad other items that are exposed to instant corrosive conditions.  Phenolic is one of the strongest materials known to industry.  Since it is so tough, Phenolic is given many tasks that would ordinarily be reserved for metals.  The machine tool industry uses it to make long-lasting gears, pinions, bushings and bearings that are quieter and more economical than metal parts. 
 

Paper with phenolic grade provides low cost electrical and mechanical properties.  It is widely used for switchboards, panel boards, insulating wafers and intricate punched parts Cotton with phenolic grade provides more mechanical strength than paper grades and has a finer surface with better machinability.  This material is used for gears, pinions, bearings, bushings and many structural applications. Glass with phenolic grade offers more mechnical strength and moisture resistance.  This grade is often used as gaskets and seals.

Glass with melamine grade is specified for mechanical strength and arc resistance.  It is used for circuit breaker parts, switchboard panels and arc barriers. Glass with epoxy grade combines high mechanical strength, good electrical properties and excellent moisture resistance.  These properties prevail at elevated temperatures.  Flame retardant grades are available.  They are used as structural members, slot insulation, wedges and panels. Glass with silicone grade combines excellent heat resistance and electrical properties.  Uses include Class H insulation, appliance insulation and high-temperature electrical equipment.
