What is Houghton Cosmolubric G68?




Houghton Cosmolubric G68 is a product of Houghton International, the world's largest and fastest-growing producer of fire-resistant hydraulic fluids. Houghton has been developing fire-resistant hydraulic fluids since the early 1950s, in response to the need for greater safety in hydraulic systems that operate near ignition sources. Today, Houghton ships more than 20 million gallons of fire-resistant hydraulic fluids a year to customers in over 100 countries.


Houghton Cosmolubric G68 is one of the products in the Cosmolubric HF Series, which are synthetic polyol ester hydraulic fluids that are chemically and thermally stable. They are formulated with antioxidants to ensure long service life and dependable performance. They also contain additives that provide corrosion protection, metal passivation, hydrolytic stability and oxidation inhibition. These products are available in two viscosity grades: ISO VG 46 and ISO VG 68.


Why use fire-resistant hydraulic fluids?




Fire-resistant hydraulic fluids are essential for hydraulic systems that operate in areas where there is a risk of fire or explosion. Conventional petroleum-based hydraulic oils can ignite easily when exposed to sparks, flames or hot surfaces, causing serious damage to equipment and personnel. Fire-resistant hydraulic fluids reduce this risk by having a higher flash point, lower volatility and lower flammability than petroleum-based oils.


Fire-resistant hydraulic fluids also offer other advantages over petroleum-based oils, such as better lubricity, higher viscosity index, lower pour point, lower toxicity and better biodegradability. These properties can improve the efficiency, reliability and durability of hydraulic systems, as well as reduce maintenance costs and environmental impact.


What are the benefits of Houghton Cosmolubric G68?




Houghton Cosmolubric G68 offers several benefits over other types of fire-resistant hydraulic fluids, such as water glycols, high water content fluids (HWCF), phosphate esters and vegetable oil-based products. Some of these benefits are:



  • High fire resistance: Houghton Cosmolubric G68 has a flash point of 290C (554F) and an autoignition temperature of 440C (824F), which are much higher than those of petroleum-based oils or other types of fire-resistant fluids. It also has a low volatility and a low flammability rating (HFDU), which means it does not produce flammable vapors or support combustion.



  • Excellent lubrication: Houghton Cosmolubric G68 has a high viscosity index of 200, which means it maintains its viscosity over a wide range of temperatures. It also has a low pour point of -40C (-40F), which means it flows easily at low temperatures. It provides superior lubrication and wear protection for hydraulic pumps, valves, cylinders and other components, reducing friction and extending service life.



  • Outstanding performance: Houghton Cosmolubric G68 has a high thermal stability, which means it does not degrade or form sludge or varnish when exposed to high temperatures. It also has a high hydrolytic stability, which means it does not react with water or form acids or corrosion products. It has a low foaming tendency and a high air release property, which means it does not cause cavitation or air entrainment in hydraulic systems. It also has a high demulsibility, which means it separates easily from water or other contaminants.



  • Safety and environmental friendliness: Houghton Cosmolubric G68 has a low toxicity and a high biodegradability, which means it does not pose a significant health or environmental hazard. It is non-irritating to the skin and eyes, and does not contain any carcinogens, mutagens or teratogens. It is readily biodegradable in soil and water, and does not bioaccumulate in aquatic organisms. It also has a low aquatic toxicity, which means it does not harm fish or other aquatic life.
