Kydex® 550 Weatherable Monolithic Sheet

Kydex® 550 Weatherable Monolithic Sheet – Unlike competitive weatherable sheet grades, super tough Kydex 550 acrylic/PVC alloy is a monolithic sheet eliminating the problems often associated with capped sheet products. This high performance thermoplastic sheet is available in gauges from 0.028″ (.71mm) and up and in eight distinctive textures. It is available in limited light colors. Impact resistance is 15 ft-lbs/in (801 J/m).

• Kydex 550 offers the properties of “Kydex” in a weatherable formulation.
• Kydex 550 sheet is highly impact resistant as measured by the notched izod impact resistance test with typical values of 15 ft-lbs/in (801 J/m), higher than most other thermoplastics.
• Kydex 550 is fire retardant (self-extinguishing) with a UL 94 V-0 rating as measured by an independent testing laboratory.
• Kydex 550 is available in seven colors: Light Gray (52120), Polar White (62000), Ivory (62015), Snowflake (62029), Natural (62059), White (62067), and Beige (72005).

Excellent forming properties result in uniform wall thicknesses and crisp detail, plus easy machining and fabricating using conventional methods, further expanding finished part possibilities.
