| Pyramid™ PEKK KD4219 | |||
| Polyetherketoneketone | |||
| Carbon Fiber | |||
| Product Description | |||
| Pyramid® KD4219 is a highly wear resistant, semi-crystalline thermoplastic compound that offers an outstanding combination of strength, toughness, chemical resistance and superior dimensional stability. Comprised of Polyetherketoneketone (PEKK) base resin reinforced with carbon fibers and proprietary lubricants, Pyramid® KD4219 is an ideal choice for sliding and rotational wear components used in environments with temperatures of up to 500°F. | |||
| Benefits offered by Pyramid® KD4219: | |||
| Outstanding Wear Resistance | |||
| Limiting PV of 32,000 | |||
| 500°F Heat Deflection Temperature Rating @ 264 psi | |||
| Extremely High Strength and Stiffness | |||
| Excellent Dimensional Stability | |||
| Very Good Resistance to Chemicals and Steam | |||
| Low Moisture Absorption | |||
| Flammability Rated UL V-0 | |||
| Easy to Machine into complex configurations | |||
| Pyramid® KD4219 is offered by Polymics in both resin pellets for injection molding or extrusion and near net shapes for machining. Resin pellets are packaged in boxes or gaylords. To meet the wide ranging needs of machinists and fabricators, Pyramid® KD4219 stock shapes are offered by Polymics in a wide array of both compression molded and injection molded shapes and sizes. Polymics' offerings include plates in sizes from 10"x10" to 12"x18" and thicknesses from 1/4" all the way to 2", rods in diameters from ¼" to 5" in lengths up to 18" long and tubular bars and discs with outer diameters up to 15". Injection molded shapes are available from existing tools in a wide variety of shapes and sizes. | |||
