Polyester resins are caused by the condensation of two or multivalued alcohols such as glycerin or glycol and di-carboxylic acids. No long chain fatty acids are used in the production. Unsaturated polyester resins are used primarily for the manufacture of fiber-reinforced plastics, resins, and fillers. Polyester resin is clear in the hardened condition, but depending on the processing it can appear cloudy or opaque. The degree of hardness depends on the composition of the ingredients and can be varied greatly. Polyester resins have high resistance against bases, gasoline, oil and weak acids. Polyester resin dissolves in strong acids, bases, esters, chlorinated hydrocarbons and ketones. Polyester resins are used as coating binders to serve as carriers of coloring pigments.
If polyester resins are ignited, they shine with a yellow smoky flame. Different methods of usage can be applied such as injection molding and press processing. Polyester resin is used in the form of plastics for electric insulation and heat-resistant handles of irons and pots. Furthermore, it can be used for insulation materials, coatings, glass, fiber-reinforced produced polyester, and much more.
