SEKISUI SPI KYDEX® T-LW Thermoplastic
Categories: Polymer; Thermoplastic

Material Notes: Light weight fire-rated sheet

KYDEX® T-LW is a fire-rated thermoplastic sheet that has the flammability characteristics of a PVC/PMMA alloy and features significant weight savings compared to standard KYDEX® T and is comparable to polycarbonate.

KYDEX® T-LW is a light-weight alternative to heavier fire-rated thermoplastics. It meets a wide range of fire safety standards including FAR 25.853(a) vertical burn, Federal Motor Vehicle Safety Standard 302, and UL 94 V-0. It offers a significant weight reduction compared to other PVC/PMMA alloys. Its wide processing window and ease of thermoforming makes it ideal for three-dimensional parts requiring crisp detail.

Suggested Applications:

  • Aircraft Interiors
  • Equipment Housings
  • Kiosk Housings
  • Mass Transit Vehicle Interior Components
  • Medical Products

Features:

  • Offers a 10% weight savings compared to KYDEX® T and is comparable to polycarbonate
  • Specific gravity of 1.21
  • Meets flammability requirements listed in FAR 25.853(a)
  • Compliant to Federal Motor Vehicle Safety Standard, FMVSS 302
  • Recognized by Underwriter’s Laboratories, Inc. as UL 94 V-0 rated in all thicknesses
  • Excellent formability and fabrication characteristics
  • Allows for tight tolerance control
  • Easy machining using conventional methods and equipment
  • Available in P-1, P-3, and P-C textures and thicknesses from 1.19mm ( 0.047”) to 6.35mm (0.250”)

Values based upon 0.125 in (3.17 mm) sheet unless otherwise specified
