Kydex® 101 Thermoplastic Sheet for Signage

Kydex 101 is an acrylic/PVC sheet capped with a weatherable cap for applications such as electrical signs requiring UL compliance. This sheet is recognized by UL to meet UL Std 746C and UL Std 94 V-0. Since the substrate is white, it eliminates the need for painting which is required with other thermoplastics and with metal. It has outstanding thermformability, impact resistance, weatherability, and machinability.

• Sign applications
• Radomes
• Other applications where a weatherable color over a white substrate is desirable


 – Kydex 101 is more rigid than most other thermoplastics resulting in parts that will deform less when loaded.
BREAKAGE RESISTANCE – With Notched Izod impact resistance of 18 ft-lbs/in (953 J/m), Kydex 101 offers unsurpassed resistance to breakage.
WEATHERABILITY – The cap offers excellent weatherability for use in outdoor applications.
Excellent forming properties result in uniform wall thicknesses and crisp detail, plus easy machining and fabricating using conventional methods, further expanding finished part possibilities.
