LG Chemical KEYFLEX BT-1140D Thermoplastic Ester for Extrusion, 40D Hardness

 

Subcategory: Polyester, TP; Elastomer, TPE; Thermoplastic

Material Notes:
KEYFLEX resins, thermoplastic elastomers divided by polyester and polyolefin type, have been developed by LG`s own polymerization and compounding technology. They display the flexibility of rubber and the strength of engineering plastics. In additions, they offer very good thermal stability, chemical resistance and weather resistance. KEYFLEX resins can be widely accepted as the replacement of thermoset rubbers.

Characterization:

  • High impact strength
  • Low specific gravity
  • Excellent resistance to chemicals and weathering
  • Good electrical properties
  • Various hardness grades (soft, semi-soft, and hard)
  • Colorability
  • Recyclability

Applications:

    Automotive: Bumper, timer ELR parts, safety belt hook, packing parts, actuator, fuel tank, remote control button

    Cable: Cable insulation, high pressure hose, wire clamp, telephone wire, computer cord, nut seal, seal parts

    Electrical and Electronic: Connector cover, connector, rubber switch, spring, timing belt

    Others: Film and sheet, packingless cap, hose, flexible coupling packing, conveyor belt, sealing parts.
