KW300High-temperature and low-temperature oil-resistant sealing grease KW300 Sealing grease for high and low temperature oil-resistant
n Product Introduction Product introduction
KW300High-temperature and low-temperature oil-resistant sealing grease is made by thickening synthetic base oil with a mixed rheological system, supplemented with various additives such as antioxidants, extreme pressure anti-wear, corrosion and rust prevention. It is prepared through special processing techniques. It meets the sealing protection requirements of valves in contact with crude oil, natural gas, water, and other media under high and low-temperature working conditions, and is also suitable for valve lubrication under heavy load conditions.
