Kydex® T Impact Resistant Fire Rated Sheet – Kydex T is a proprietary acrylic/PVC thermoplastic sheet that is cost competitive with fire retardant ABS/PVC (FR-ABS) formulations but with significantly higher impact strength and extensibility. Unlike FR-ABS, because Kydex T is less hygroscopic, Kydex T typically does not requiring pre-drying; offers superior impact resistance 15 ft-lbs/in (801 J/m); more uniform forming with less wall thinning; and offers significantly greater resistance to a broad range of corrosive chemicals and cleaning solutions. It is available in a wide range of aesthetic choices and is UL recognized Std 94 V-0/5V.
• External housings for equipment such as photocopy machines, instrument panels, computers, keyboards, telephones, etc.
• Internal parts for equipment such as vending machines, air ducts, grilles, etc.
• Orthopedic braces
• Medical equipment parts (for example, centrifuge covers, blood analyzers, etc.).
• In-store displays
• Electrical equipment and any components requiring an UL 94 V-0 rating
Kydex T is formulated to substitute for FR ABS sheet with competitive pricing but superior cost/performance.
Kydex T has higher breakage resistance as measured by the Notched Izod test than competitive thermoplastics.
Kydex T is available in eight gauges from 0.028″ (.71mm) and up, in nine textures, a large variety of colors, custom blank sizes, and very low minimums.
Kydex T is among the most rigid of thermoforming materials, with a modulus of elasticity of 350,000 psi (2482 MPa).
Kydex T is easy to form with excellent part definition and deep-draw characteristics. It forms with similar forming times to FR-ABS making it easy transition from competitive products.
