牌号简介 About |
---|
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 KetaSpire® KT-810FP is the fine powder form of KT-810 resin. 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 and its fine powder analog KT-820FP. 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 300°C (572°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-810FP is designed for compression molding applications such as machined parts and stock shapes wherein the fine powder form is easier to work with in a compression molding process. The KT-810FP comes with a median particle size that is typically in the 35-50 micrometers (µm) range. The KT-810 grade is available for extrusion and injection molding processing in natural pellet form under the grade name KT-810 NT. |
