科慕Chemours Krytox GPL204

Krytox GPL204润滑脂是聚四氟乙烯增稠的，不含添加剂，可用于与化学品接触的部件。典型的应用包括与化学品接触的阀门、仪器或轴承，包括醇、氨、溶剂、蒸汽、酸和碱，以及氧气系统，包括LOX和GOX。它们通常用作密封和o形环润滑剂，并与几乎所有类型的密封兼容。

Krytox GPL 204 grease has an Oil Viscosity of 60 cSt at 40°C and the estimated useful temperature range is -51°C to 179°C.

Krytox GPL 204 Grease | General-Purpose Lubricants

Ultra-High Performance, 100% Non-flammable, Chemically Inert Lubricants

Krytox GPL 204 grease is the product of choice in extreme temperature conditions. Most petroleum products begin to degrade above 99 °C (210 °F) and are too viscous at temperatures just below –18 °C (0 °F). Under the D-3336 test conditions of 177 °C (350 °F) and 10,000 rpm, the majority of competing hydrocarbon lubricants fail in less than 1,000 hr. But, the general-purpose line of Krytox lubricants has been shown to last over 5,000 hr without failure, even at an increased temperature of 200 °C (392 °F). This extreme condition performance is what distinguishes Krytox performance lubricants from other competing products.

Krytox GPL 204 grease is cost-effective across a wide range of applications. Due to their inert nature, Krytox lubricants provide a much longer usable life as compared to typical hydrocarbon oils and greases; and the longer usable life allows them to remain for considerable periods of time before needing to be replaced if they are replaced at all. That translates to savings over time, both by lowering the amount of lubricant purchased and any downtime incurred during re-lubrication.

Standard Krytox lubricants contain only carbon, oxygen, and fluorine; whereas, hydrocarbons contain hydrogen. The absence of hydrogen greatly increases the stability of the lubricants and renders them non-flammable with no flashpoint. They will not burn or support combustion, even in an environment of 100% liquid or gaseous oxygen. For applications that require GPL 201 and an extreme pressure additive, we recommend Krytox GPL 214, or if potent anti-corrosion is required Krytox GPL 224
