LG Chemical LUCEL FW-700A Friction and Wear Resistant POM, Polymeric Wear Additive  (discontinued **)
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM)

Material Notes: LUCEL semi-crystalline acetal copolymer resins are produced by gas phase polymerization. LUCEL resins can be widely accepted as the replacement of thermosets, aluminum and zinc die-casts or other metals.

Characteristics:

  • No pungent smell in processing
  • Excellent thermal stability based on structure of Acetal Copolymer
  • Well balanced mechanical properties and resistance to creep
  • Highest fatigue resistance to organic and chemical and hot water
  • Excellent friction and abrasion resistance
  • High dimensional stability and good moldability
  • Easy part design and application over a broad range of environmental conditions

Applications:

    Automotive: Water valve parts, radiator drain cock, carburetor float, exhaust gas valve, diaphragm valve, door lock, winker switch, wiper gear and pivot bearing, speedometer gear, window glass bottom channel, safety belt, retractor parts, door handle, lumbar support handle, sun visor bracket, collapsible room mirror stay, fender mirror body, waster pump nozzle

    Electrical and Electronic: Switch, coil bobbin, micrometer base, tuner parts, control switch parts, dial mechanism, cassette tape reel, power transmission gear, shaft nearing, bracket, fan motor housing, spring frame of headphone, arc shooter, toner agitating rotor, printer mechanism, gas meter component

    Industrial Parts and Others: Spring, bearing, spray guns, power cylinder, watch gear, alarm clock base, hot water pot housing, gear housing, table top chain runner, zipper, partition corner piece curtain runner, blind gear, door runner, office furniture parts, accessories, comb, pressure container
