KYDEX®
High impact, fire-rated injection molding compound

DESCRIPTION
KYDEX® compound is a fire retardant acrylic/PVC injection molding compound that offers exceptional impact resistance, chemical resistance, and processability, allowing production of parts which are difficult to mold and/or intended for demanding end-use applications.

FEATURES

  • High Impact Resistance:
    Depending on grade KYDEX compound offers Notched Izod impact resistance to 18 ft-lbs/in. (953 J/m), providing extreme resistance to cracking and abuse.
  • Broad Chemical Resistance:
    Parts molded of KYDEX compound exhibit exceptional resistance to a wide range of caustic and acidic chemicals, including harsh cleaning agents and solvents.
  • Extreme Fire Retardancy:
    Depending on grade KYDEX compound carries fire ratings of UL STD 94V-0 and FAR 25.853(a), meeting flammability standards for electrical equipment, aircraft, automotive, and mass transit vehicle applications.
  • Color stability:
    Depending on grade parts molded of KYDEX compound exhibit long-term indoor UV color stability. Exterior weatherability is dependent.
  • Depending on grade KYDEX compound exhibits flexural modulus to 440,000psi (3031 MPa).

APPLICATIONS

  • Electrical equipment
  • Business machines
  • Computer equipment
  • Medical equipment
  • Appliances
  • Aircraft interiors
  • Mass transit vehicle interiors
  • Automotive interiors
  • Other high performance applications

PROCESSING CHARACTERISTICS
Although KYDEX compound exhibits excellent thermal stability, observing the following parameters will produce the best results:

  • Melt temperature should not exceed 400°F (204°C)
  • Use the smallest cushion possible 1/4 in. (6.35mm)
  • Screw should reach back position (5 seconds before mold opens)
  • Residence time in the mold should be minimized (less than 10 minutes recommended)
  • Back pressure should be set in the range of 100 to 400 psi (.69MPa-2.75Mpa) to ensure a homogeneous melt
  • Mold neutralization after use is recommended
