Jialede's YBS-205 perfluoropolyether grease has been successfully applied to automotive EGR valves.

At Jialede Fluorochemical Lubricants, we are always customer-oriented. On July 22, 2024, Mr. Li from an automotive parts manufacturing technology company inquired about the suitability of DuPont GPL-205K perfluoropolyether grease for automotive contact grease and conductive grease. We confirmed its suitability for automotive applications and recommended Jialede's Youbangshou brand, YBS-205 perfluoropolyether grease, offering stable performance at a price over 60% lower than international brands.

On August 8, Mr. Li explicitly requested an alternative to GPL-205 and provided detailed testing requirements, including: room temperature resistance comparison, 48-hour delamination test at 160°C, 144-hour resistance test under thermal cycling conditions of -40°C to 150°C, 144-hour mechanical endurance test, and verification of EGR valve minimum duty cycle and sensor voltage deviation at different temperatures. Engineer Li explained that the company specializes in EGR valves, with an annual production capacity exceeding one million units. The grease is primarily used for valve stems with a diameter of 4mm and a length of 40mm.

In response to this request, we promised to send a 50g sample of YBS-205 and the accompanying solvent, explaining that a 10%-20% performance degradation during thermal cycling testing would be considered unqualified. Engineer Li subsequently engaged in in-depth discussion regarding the impact of low-temperature mechanical motion on the grease, and we provided professional answers.

On September 8th, Engineer Li reported that the YBS-205 perfluoropolyether grease had successfully passed all tests and would enter the procurement process for a quantity of one million units. He emphasized the importance of ensuring quality during the order. We solemnly pledged that YBS-205 is a mature product, strictly adhering to the IATF 16949 quality management system. All batches undergo comprehensive testing before shipment to ensure they meet the high standards of the automotive industry. Galode will continue to provide high-performance perfluoropolyether grease solutions to the automotive industry to help the stable development of parts manufacturing.
