- Product Highlights
High quality synthetic esters are widely used as compressor base stocks due to their excellent thermal/oxidative stability, low volatility, and wide operating temperature range. They provide clean operation for long life at elevated temperatures. Reciprocating and rotary vane compressors take advantage of the inherent lubricity and solvency of diesters and trimellitates while rotary screw and centrifugal fluids benefit from the extreme oxidative stability of polyol esters. Refrigeration grades (SRL) have optimized miscibility and flow properties with the refrigerant gas at high and low temperatures. Diesters are low to medium viscosity synthetic base stocks that have two ester groups. Most diesters are made from a dibasic acid combined with monofunctional alcohols, while a polyol diester is made from a synthetic glycol and monofunctional acids.
Diesters are known for outstanding low temperature properties, lubricity and solvency. The polar ester groups provide excellent high temperature stability and low temperature fluidity. When comparing diesters to hydrocarbon oils and other synthetics with the same viscosity, a diester fluid will have a higher flash point, lower volatility and better thermal stability. Diesters improve additive solubility and seal conditioning, while offering natural high viscosity index thats boosts lubrication efficiency. Synthetic esters are available in a wide variety of viscosity grades and deliver an excellent combination of oxidative stability, low temperature fluidity, lubricity and high viscosity index in greases formulated with high performance thickeners. Low volatility and a favorable eco-toxicity profile make synthetic esters an excellent choice for greases that are used in outdoor partial loss applications or in environmentally sensitive areas. Synthetic esters are used in the textile industry to lubricate and protect both fibers and machinery. Fibers move through textile processing equipment at very high speeds, creating friction and heat that causes wear of stationary parts and degradation of the fibers. A good lubricant will reduce heat, friction and wear on high speed spindles and bearings, allowing the machines to run faster with less down time due to fiber breaks and snags.
Synthetic ester lubricants will not have negative impact on the color, look or feel of clothing, carpet or other textiles. They can be easily removed by washing or baking, leaving no residue that can impact dyeing or post-processing. A textile lubricant should not stain the fiber or form varnish on the machine.
A variety of esters are used in the textile industry to address the many different types of fibers and mechanical operations. Zschimmer & Schwarz has a long history of providing components for both neat esters and spin finish emulsions for the textile industry, and can recommend the appropirate solution for any type of fiber lubricant application.
