Selection of the best lubricant involves analyzing operating conditions and choosing from the many synthetic and petroleum-based products available today. While most petroleum products begin to degrade before 99 °C (210 °F) and cease turning at temperatures just below –18 °C (0 °F), Krytox XHT fluorinated synthetic lubricants have operating ranges that are significantly broader (–70–316 °C [–94–600 °F]).
Krytox lubricants are more effective at even higher temperatures, regardless of operating duration. Using base oils, thickeners, and additives with chemistry designed to create high and low viscosity, these products are targeted for use solely in the very high-temperature range. Available in several grades that offer anti-corrosion, extra bonding, and non-melting properties, these lubricants have applications in a variety of industries, including chemical, textile, tire, aviation, conveyor, glass, plastic film, non-woven manufacturing, and mining and metal processing.
Because of its thermal stability and non-oxidizing characteristics, Krytox is a natural high-temperature lubricant. Krytox XHT greases are available with useful temperature ranges up to 360 °C (680 °F) for continuous use, with spikes to 400 °C (752 °F), when used in proper metallurgy with periodic re-lubrication.
