Ecco Grease HP870-S is a white perfluoropolyether grease made from polytetrafluoroethylene (PTFE) thickened highly chemically stable perfluoropolyether oil (PFPE) and added with special anti-corrosion additives. . This high-temperature fluorine grease is designed for bearings in high-temperature, high-load, chemically-corrosive environments and parts that require lifetime lubrication. It has excellent chemical inertness, durability, and low volatility. Applicable temperature range: -35 ~ +280 °C. Features: ※ Extremely wide working temperature, excellent high temperature stability and oxidation stability; ※ Consistency varies little with temperature, extremely low volatility, extremely long service life; ※ Excellent anti-wear, anti-scratch and anti-combustibility , anti-radiation, anti-corrosion; ※ Low coefficient of friction, high load capacity, good compatibility with most rubbers and plastics ※ Water, oil, vacuum (low vapor pressure), most organic solvents and strong acid and alkali resistant . Recommended Applications: ※ High-temperature, long-life lubrication for automotive idle control valves, electronic throttles, airbag sensors, and exhaust gas recirculation valves. ※ Used for the lubrication and sealing of bearings, pumps, valves, and seals in high vacuum or dust-free environment equipment for semiconductors, liquid crystals, and optoelectronic process equipment; also used in contact with corrosive gases, liquids (such as halogens, liquid oxygen, etc.) Pumps, Valves; ※ Used for lifetime full-life lubrication of precision machinery, optical instrumentation, office equipment, and clean room equipment.
Heavy Calcium Carbonate
It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
