KetaSpire KT -820是低流动级未增强聚醚醚酮(PEEK),呈润滑颗粒状。KetaSpire PEEK按照行业最高标准加工,以兼具不同的性能为特征,包括优异的耐磨损性、一流的抗疲劳性、易于熔融加工、高纯度、优异的耐有机物、酸和碱等化学物质的性能。 这些特性使得它非常适合医疗保健、交通运输、电子、化学处理和其它工业用途。KetaSpireKT -820可以很容易地使用常规注塑成型和挤出工艺进行加工。有本色粗粉末牌号KetaSpire KT- 820P供配混。 粒状KT- 820微量喷洒了润滑剂硬脂酸钙( 0.01 % ),方便颗粒在塑化螺杆中的输送。有类似于非润滑本色低流量牌号KetaSpire KT -820 NL可供 。 黑色:KT-820 BK 95 PRELIMINARY DATA SHEET KetaSpire® KT-810 is an ultra-high molecular weight natural PEEK resin having a melt viscosity ranging from 0.51-0.65 kPa-s as compared to 0.38-0.50 kPa-s for standard high-viscosity PEEK grades such as KT-820. KetaSpire PEEK is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent chemical resistance to organics, acids and bases; exceptional retention of mechanical properties up to 240°C (464°F); best-in-class fatigue resistance; excellent wear resistance; ease of melt processing; and high purity. The KT-810 grade achieves a greater level of mechanical toughness than previously possible with PEEK, yet it is still processable by conventional methods including extrusion, injection molding, and compression molding. KetaSpire® KT-810 is particularly suited for compression molding applications such as machined parts and stock shapes wherein the inherent slow cooling rates of the process limit PEEK's toughness and often result in brittleness due to the higher crystallinity levels. The grade is available in two forms: fine powder with average particle size of approximately 50 micrometers (µm) for compression molding, and pellet form for extrusion and injection molding. The fine powder grade is designated KT-810FP while the pelletized product is available as KT-810 NT. Fine Powder: KT-810 FP Natural Pellet: KT-810 NT |
