Kydex® (PVC/acrylic alloy)


  • Extremely durable acrylic PVC extruded in a range of col­ors, pat­terns, tex­tures, thick­nesses and grades
  • Spe­cial­ized grades of Kydex sheet meet spe­cific UL, FAR, MVSS, ASTM and/or BS fire ratings
  • Exhibits excep­tional mechan­i­cal prop­er­ties and chem­i­cal resistance
  • Fire-resistant
  • Low mois­ture absorption
  • Resis­tant to chip­ping and crack­ing mean great fab­ri­ca­tion and machin­ing prop­er­ties and flexibility
  • Can be drilled, punched and cut using stan­dard wood­work­ing or metal work­ing tools

Com­mon uses

  • Kiosk hous­ings
  • Med­ical products
  • Equip­ment housings
  • Air­craft interiors
