KW300高低温耐油密封脂
KW300 Sealing grease for high and low temperature oil-resistant
产品简介 Product introduction
KW300高低温耐油密封脂采用混合流变体稠化合成基础油，辅以抗氧、极压抗磨、防腐、防锈等多种添加剂，经特殊工艺制备而成。满足与原油、天然气、水等介质接触的阀门在高低温工况环境中阀门密封防护，也适用于重载负荷下阀门润滑。
KW300 high and low temperature oil-resistant sealing grease is made of synthetic base oil thickened with mixed rheology, supplemented by various additives such as antioxidant, extreme pressure anti-wear, anti-corrosion, and anti-rust, and is prepared through a special process. It is suitable for valve sealing protection in high and low temperature environments for valves in contact with crude oil, natural gas, water and other media. It is also suitable for valve lubrication under heavy loads.
