An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.

Bio-based binder systems

A method for producing a high viscosity, low volatiles blown stripped oil blend is provided. The method may include the steps of: (i) obtaining an oil blend of corn stillage oil and soybean oil having a weight ratio of corn stillage oil to soybean oil of from about 1:2 to 3:1; (ii) heating the oil blend to at least 90° C.; (iii) passing air through the heated oil blend to produce a blown oil having a viscosity of at least 50 cSt at 40° C.; and (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram.

The method may include the steps of: (i) obtaining an oil blend of corn stillage oil and soybean oil having a weight ratio of corn stillage oil to soybean oil of from about 1:2 to 3:1; (ii) heating the oil blend to at least 90&#xb0; C.; (iii) passing air through the heated oil blend to produce a blown oil having a viscosity of at least 50 cSt at 40&#xb0; C.; and (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram.

Polymeric additives are disclosed for compressor lubricants which can reduce the tendency of the lubricant to become entrained in compressed gases and be carried forward as fine dispersed droplets in compressed gas systems such as compressed air, natural gas, and compression refrigeration systems.

Lubricant useful for improving the oil separation performance of a vapor compression system

A problem with refrigeration systems using ammonia as the refrigerant and hydrocarbon lubricants is that the seals/gaskets of the systems have a tendency to harden and shrink. This can cause leakage of the refrigerant and eventually require disassembly of the equipment and replacement of the seals. The addition of a small amount polyether having an aromatic fragment of 6-18 carbon atoms or an aliphatic fragment of 10-22 carbon atoms can soften the seals and partially re-swell the seals solving the leakage problem and avoiding expensive maintenance costs. Alternatively a polyether of 1,2-butylene oxide which is more oil soluble than most other polyethers with a smaller Z group e.g. derived from alkanols of 1 to 9 carbon would be effective at reducing hardening and shrinkage.

Lubricant composition for ammonia based refrigerants with good seal performance

Lubricant composition comprising an aliphatic substituted naphthalene alone or in combination refrigeration systems

The present invention relates to a lubricating basestock comprising a blend of (A) at least one polyalkylene glycol and (B) at least one alkyl aromatic. Additives, such as antioxidants, corrosion inhibitors, and metal deactivators, can be added to the lubricating basestock. In one embodiment, the lubricating composition is free of naphthol. The blend can also be used in combination with a variety of oils of lubricating viscosity, with or without additives therein. According to the present invention, the lubricating composition exhibits excellent oxidation and thermal stability, demulsibility, and hydrolytic stability. The lubricating composition is particularly useful as a positive displacement compressor lubricant.
