Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.
Some of these chemistries are polyether, polyester, [6] polycarbonate [7] [8] and also acrylic polyols. [9] [10] Polyether polyols may be further subdivided and classified as polyethylene oxide or polyethylene glycol (PEG), polypropylene glycol (PPG) and Polytetrahydrofuran or PTMEG. These have 2, 3 and 4 carbons respectively per oxygen atom in ...
In the industrial production of PHA, the polyester is extracted and purified from the bacteria by optimizing the conditions of microbial fermentation of sugar, glucose, or vegetable oil. In the 1980s, Imperial Chemical Industries developed poly(3-hydroxybutyrate- co -3-hydroxyvalerate) obtained via fermentation that was named "Biopol".
Because the major components of an alkyd coating, i.e. fatty acids and triglyceride oils, are derived from low cost renewable resources, the cost of alkyd coatings has remained very low despite the ever-increasing cost of petroleum, which is the predominant raw-material source of most other coatings such as vinyls, acrylics, epoxies and ...
Microfiber is typically comprised of a blend of polyester and nylon, so it needs a different treatment than your typical fabric cushion. Thankfully, cleaning these cushions is still a relatively ...
Instead, Peters maintains that rubbing alcohol will work for fabrics like cotton and polyester. “Even wool can handle some rubbing alcohol but leather will require a different approach,” he adds.
But when omitting alcohol from a drink you need to consider a range of factors: alcohol adds body and richness to drinks, it balances sweet flavors, and its astringency adds texture.
