Polyester Polyol Reactors (PET/PA) - Pofi
Polyester polyols may also be used as a reacting species in the production of polyurethanes. They can be obtained as a byproduct of terephthalic acid production. They are typically based on saturated aromatic carboxylic acids and diols. Branched polyester polyols are used for polyurethane … · The key difference between saturated and unsaturated polyester resin is that the saturated polyester resins have no double bonds in their main chain whereas the unsaturated polyester resins have double bonds in their main chain.. A polyester is a polymer compound that forms from the condensation reaction between a polyol and an acid. Therefore, we can categorize them as …

WO2010015642A1 - Aromatic polyesters, polyol blends ...
polyether polyols production as a category of major sources. The end use of a polyether polyol is determined by the properties of the polyol. Polyether polyols fall into two main classifications: high-molecular-weight, linear or slightly branched polyether polyols (urethanes), and low-molecular-weight, highly branched polyether polyols Renewable polyester polyols were synthesised according to the literature procedure with some modification [].In particular, 0.05 mol of eugenol diol and 0.04 mol of dimer fatty acid with 0.5 % DBTDL as a catalyst were taken in a tree necked flask and dipped in an oil bath, which was heated at 160 °C.

Polyols for Polyurethanes – Chemical production and ...
Polyether Polyols & Polyester Polyols. There are two main classes of polyols used in polyurethanes: polyether polyols and polyester polyols. Although both polyether polyols and polyester polyols are used in coating, adhesive, sealant and elastomer applications (collectively referred to as CASE), polyether polyols are more often used in flexible foam, while polyester polyols are more commonly ... Adipates are polyols based on adipic acid used for CASE applications (elastomers, shoe soles and coatings). Product applications Polyols based on PET and PA are high-quality polyester polyols, which fit perfectly into the formulations for insulation foams, cast resins, sealants or adhesives.

So the advantage is that you may be able to use the NIR probe as a rapid way to determine OH# - this can be of interest for example as a probe placed in the polyol synthesis reactor in situ. Unsaturated polyester, any of a group of thermosetting resins produced by dissolving a low-molecular-weight unsaturated polyester in a vinyl monomer and then copolymerizing the two to form a hard, durable plastic material. Unsaturated polyesters, usually strengthened by fibreglass or ground mineral, are made into structural parts such as boat hulls, pipes, and countertops.
