| Pyramid™ KD4219是一种高耐磨、半结晶热塑性化合物，具有优异的强度、韧性、耐化学性和尺寸稳定性。Pyramid™ KD4219由碳纤维和专用润滑剂增强的聚醚酮（PEKK）基树脂组成，是在温度高达500°F的环境中使用的滑动和旋转磨损部件的理想选择。Pyramid™ KD4219提供的好处：优异的耐磨极限pv为32000 500°F热变形温度压力等级@264 psi，强度和刚度极高，尺寸稳定性极佳，耐化学药品和蒸汽，低吸湿性，易燃性，额定值UL V-0，易于加工成复杂结构，Pyramid™ KD4219由聚碳酸酯提供，用于注塑或挤出的树脂颗粒和用于机械加工的近净形状。NG。树脂颗粒包装在盒子或盖洛德。为了满足机械师和制造商的广泛需求，Polymics提供Pyramid™ KD4219库存形状，包括压缩成型和注射成型形状和尺寸。Polymics的产品包括尺寸从10“x10”到12“x18”的板材和厚度从1/4“一直到2”的板材，直径从1/4“到5”的棒材，长度从18“到18”的管材和外径高达15“的盘片。现有工具可提供各种形状和尺寸的注塑成型形状。 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. |
