polyesterharpiks
Polyesterharpiks is a synthetic resin produced by the esterification of a diol or polyol with a dicarboxylic acid or its anhydride. This chemical process results in a polymer that can be dissolved in a reactive diluent, typically styrene, to form a liquid resin. When a catalyst is added, the resin undergoes a curing process, transforming from a liquid to a solid, rigid material through a process called cross-linking.
This type of resin is widely used in the manufacturing of fiberglass reinforced plastics (FRP), often referred
There are various types of polyesterharpiks, including orthophthalic, isophthalic, and terephthalic polyesters, each offering slightly different
