UPR

Unsaturated polyester resins are thermosetting resins produced by the reaction of polyesterification between dicarboxylic acids (saturated and unsaturated) and glycols. The final mixture is obtained by dissolving the resulting resin (a solid polymer at room temperature) in an unsaturated and reactive solvent, normally styrene.

The crosslinking reaction is obtained by the addition of organic peroxide which acts as an initiator, leading to the formation of a complex three-dimensional network generating a solid irreversible state.

Polynt produces several anhydrides (phthalic and maleic anhydride) and dicarboxylic acids (fumaric acid) used for the synthesis of polyester resins: these raw materials, along with the strong formulation know-how gained over the years, has allowed Polynt to develop the following families of resins.
