Halocarbon 28 grease
Halocarbon 28 润滑脂是一种中等稠度、中等粘度的 PCTFE 油，用二氧化硅增稠，设计用于以常见环境条件为中心的应用。这种惰性油是通过受控聚合过程制造的，然后经过稳定处理以赋予它一些非常独特的特性。这种油是安全的、化学惰性的、不可燃的，并且与氧气和氯气相容。它具有良好的润滑性、高热稳定性和低压缩性。alocarbon 28 grease is a medium bodied, moderate viscosity PCTFE oil thickened with silica designed for applications centered around common ambient conditions. This inert oil is manufactured by a controlled polymerization process and then is stabilized to give it some very unique properties. This oil is safe, chemically inert, nonflammable, and is oxygen and chlorine compatible. It has good lubricity, high thermal stability, and low compressibility.
The thickener used in this grease is a very fine silica powder. Silica is a commonly requested grease thickener, but its chemical stability is more limited than the PCTFE oil. Silica-thickened greases can be prone to attack by chemicals active toward silica, such as alkalis, hydrofluoric acid, and fluorinating agents. Compatibility of silica-thickened greases should be confirmed before being used in applications in contact with these chemicals.
Typical applications for this grease include valve lubrication and seals.
