Polyols

Polyols are basic building blocks for many chemical applications, such as:

  • Polyesters for powder coating, coil coating
  • Unsaturated polyesters and reinforced plastics
  • Alkyd resins, solvent and waterborne
  • Polyurethanes for coating, foams and elastomers
  • Lubricant esters

Pentaerythritol

Pentaerythritol is a polyalcohol containing four primary alcoholic groups symmetrically bound to an atom of carbon. Pentaerythritol is a white, water-soluble crystalline powder, and a versatile building block for the preparation of many poly-functionalized compounds such as branching monomer for alkyd coatings, polyol esters for lubricants, rosin esters, PVC stabilizers.


Feedstocks are formaldehyde and acetaldehyde.
Eurotecnica offers a Pentaerythritol process that features top purity, continuous reaction, easy operability and low investment cost.

Other important features are:

-     Crystallization by cooling (energy saving and production of crystals of optimum size for filtration and drying)

-     Filtration by belt filters (low cake moisture, best washability, machinery reliability)

-     By-product recovery by solvent extraction (max recovery and high purity sodium formate)


TMP Trimethylolpropane

Trimethylolpropane is an organic compound containing three hydroxy functional groups, widely used as building block in the polymer industry.

Main applications are in alkyd resins, saturated polyesters, synthetic lubricants, monomers/oligomers for radiation curing pigment coating and polyurethanes for coatings and foams. Feedstocks are formaldehyde and n-butyraldehyde

Eurotecnica offers a TMP process that features top purity, continuous reaction, easy operability and low investment cost.

By-product recovery by solvent extraction provides max recovery and high purity sodium formate.


NPG Neopentylglycol

Neopentylglycol is a polyalcohol containing two primary alcoholic groups symmetrically bound to an atom of carbon.

As the other polyols of this family, it is a basic building block for many chemical applications, such as polyesters for powder coating, coil coating and other stoving enamels, unsaturated polyesters for gel-coats and reinforced plastics, alkyd resins, solvent and waterborne polyurethanes for coating, foams and elastomers lubricant esters.
