Thermosets
Canvas is an economical choice for fabricated parts

Canvas (C, CE)

  • Good mechanical and impact strength
  • Withstands continuous operating
    temperature of 250° F
  • Good insulation properties
  • Economical
  • Durable and stable
  • Low moisture absorption

Characteristics

C and CE grade phenolics are composed of a continuous cotton woven cloth impregnated with a phenolic resin binder. Phenolics are the oldest general purpose thermoset resin and are among the least expensive and easiest to process.

Canvas grades C and CE are durable and economical choice for many applications. Both canvas grades provide good wear resistance, low moisture absorption and good mechanical strength. Grade C is suitable for structural and mechanical applications. Grade CE is an electrical grade canvas with good insulation properties.

Applications

  • Structural supports
  • Piston rings
  • Gears, spacers and bearing surfaces
