Ensinger PEI

Shinil Chemical SHINCON PEEK-CF LCD Rack
Categories: Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Carbon Fiber Filled

Material Notes: LCD Rack is used to transfer or bake LCD frame in the electronic assembly or LCD packaging assembly line. Current LCD Rack is made of poly ether ether ketone (PEEK) with carbon fiber (CF). Since both materials cost high, there is a need to design the material with cost effectiveness. Also, the current LCD Rack has a concern of sloughing by CF particulates. SHINIL sloves these problems with the CNT composite of polyphenylene sulfide (PPS), polyether sulfone (PES), PEEK, or polyether imide (PEI) by providing the cost effectiveness combined with enhanced mechanical properties. Especially, the wear resistance (coefficient of friction, coefficient of abrasion) of SHINIL CNT composite was much lower than the current PEEK material, which will provide the material for clean/dust free LCD operation environments.

    Features and Benefits
  • Permanent electro conductivity
  • Improved mechanical properties
  • No particulates and no sloughing
  • Lighter weight
  • Recyclability
  • Low abrasion and friction
  • Improved surface
  • Cost effective
