The unique Ketjenlube™ polymeric esters are high performance additives used in a variety of lubricant applications both synthetic and mineral based. The structure of these esters consist of a carbon backbone carrying both polar ester and nonpolar hydrocarbon side chains. The length of the carbon backbone can be varied, as well as the relative proportions of ester groups and hydrocarbon groups, resulting in a wide range of properties applicable to diverse applications, and compatibility with Group I, II, and III mineral oils and PAO's. When used with PAO or Group III base stocks, it is often possible to eliminate the use of seal swell additives, due to Ketjenlubes'™ compatibility with common seal materials.
Ketjenlubes™ are available in viscosities from 15 to 3000cSt at 100 degrees C. However, the average molecular weights do not exceed 10,000 Daltons, and are linear in structure there by ensuring excellent shear stability. The combination of low volatility, high viscosity index (VI) and excellent oxidative and hydrolytic stability makes them a great choices for high temperature industrial applications. Many are also clean burning, without smoking, useful for low smoke two-stroke engine oils.
The Ketjenlube™ 115, 135, 165 and 1300 have the highest ester content and polarity, giving them superior load carrying capacity. These esters are widely used in metalworking applications both forming and cutting. Their excellent inherent lubricity along with strong synergy with conventional extreme pressure/anti-wear additives, including sulfur and phosphorus bearing additives, make them an excellent choice for use in packages designed to replace chlorinated additives in heavy duty metalworking fluids.
The diversity offered in the Ketjenlube™ product range makes them uniquely suited for use across many applications including transportation, industrial maintenance fluids, greases, metalworking fluids, Industrial as well as automotive gear and NSF certified HX-1 food grade lubricants. Common to all Ketjenlubes™ are:
- oxidative and shear stability
- high viscosity index (VI)
- low volatility and
- superior lubricating capabilities, thus providing limitless possibilities in high performance lubricants.
Italmatch Chemicals also supplies emulsifiers and phosphorus based lubricating additives for metalworking fluids. The Dapral™ PA series are 100% active PIBSA emulsifiers, of various molecular weights, produced via a chlorine-free process. These co-emulsifiers provide enhanced hard water tolerance and bio-stability in emulsifiable oils and semi-synthetic fluids. The Dapraphos™ ethoxylated phosphate esters are multifunctional additives contributing to extreme pressure/anti-wear, passivation, emulsification and corrosion preventative properties aimed at white metals.
