How does Isophthalic Acid enhance the performance of polyester resins?
Isophthalic acid a rigid benzene ring structure, which can restrict the movement of its molecular chains. When added to polyester resins, it can strengthen the rigidity of the molecular chains, increasing the glass transition temperature and melting point of the resin. This allows the material to maintain stable performance at higher temperatures, especially suitable for high-temperature environments, such as cars and appliance casings.
