| 聚四氟乙烯7C X是一种白色粉末，粒径小。它最独特的特点是颗粒的不规则纤维特性。即使在相对较低的成型压力下，聚四氟乙烯7C X的小颗粒尺寸也有助于减少空隙。纤维颗粒能促进无机填料在添加后的良好捕获和均匀分布，从而改善成型材料的机械性能。聚四氟乙烯7c x表现出相对较高的模具收缩率。特氟隆聚四氟乙烯7C X是首选的模具要求最佳的机械和电气性能。它相对较低的体积密度限制了从一个给定的模具或压力开口成型的尺寸。它通常是制造填充化合物的首选，尤其是与由于密度差异而难以混合的金属粉末。由纯聚四氟乙烯7C X制成的经过适当处理的产品具有典型的氟聚合物树脂的优良性能：在260°C（500°F）下使用后的性能保持不变，在-240°C（-400°F）下的有用性能，几乎对所有工业化学品和溶剂的化学惰性，以及低摩擦和防静电表面。介电性能优异，频率和温度稳定。模制品具有中等刚度和较高的极限伸长。在火焰情况下，聚四氟乙烯7C X产品能抵抗点燃，本身不会促进火焰蔓延。当被其他来源的火焰点燃时，它们的热量贡献很小，烟很少。与火焰情况下的行为相关的声明或数据不旨在反映实际火灾条件下该材料或任何其他材料所带来的危险。典型应用许多最终产品是由聚四氟乙烯7C X的成型件成型或制造，或由聚四氟乙烯7C X的填充化合物制成。填充化合物提供了多种改性机械性能。使用特氟隆聚四氟乙烯7C X的最终产品包括刮膜和薄片、垫圈、桥或管道轴承垫、活塞环和隔膜。 Teflon ® PTFE 7C X is a white powder with small particle size. Its most unique feature is the irregular, fibrous character of the particles. The small particle size of Teflon ® PTFE 7C X helps to minimize voids even at relatively low molding pressures. The fibrous particles promote good capture and uniform distribution of inorganic fillers when they are added to modify the mechanical properties of moldings. Teflon ® PTFE 7C X exhibits relatively high mold shrinkage. Teflon ® PTFE 7C X is preferred for moldings requiring optimum mechanical and electrical properties. Its relatively low bulk density limits the size of moldings from a given mold or press opening. It is often preferred for making filled compounds, especially with metal powders that are difficult to mix because of density differences. Properly processed products made from neat Teflon ® PTFE 7C X provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 260 °C (500 °F), useful properties at -240 °C (-400 °F), chemical inertness to nearly all industrial chemicals and solvents, and low friction and antistick surfaces. Dielectric properties are outstanding and stable with frequency and temperature. Molded products have moderate stiffness and high ultimate elongation. In a flame situation, products of Teflon ® PTFE 7C X resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, their contribution of heat is small and with very little smoke. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions. Typical Applications Many end products are molded or fabricated from moldings of Teflon ® PTFE 7C X, or made with filled compounds based on Teflon ® PTFE 7C X. The filled compounds provide a wide choice of modified mechanical properties. End products using Teflon ® PTFE 7C X include skived film and sheet, gaskets, bridge or pipeline bearing pads, piston rings, and diaphragms. |

原料纯苯及环己酮价钱跌跌不休
2018-11-14 原料纯苯及环己酮价格跌跌不休，己内酰胺成本面支撑减弱，但厂家装置近期意外检修事故频发，加之部分厂家检修计划多集中在11月初，整体行业开工率持续下跌，较低的现货供应量将现货价格维持在相对平稳的水平。 原本在10月份“一路高歌”的己内酰胺行业开工率进入11月份出现“滑铁卢”式下跌，截至11月12日，行业开工率跌至6成左右，近10天内行业开工率下降近15个百分点。进入11月，厂家因意外事故停车检修的情况屡见不鲜，南京东方、巴陵恒逸、巴陵石化、福建天辰、江苏海力、山东海力等半数以上 |
