vinyyliester
Vinyl ester, also known as vinyl ester resin, is a type of thermosetting polymer that is formed by the esterification of unsaturated polyester resins with vinyl monomers. This process results in a resin with properties that bridge the gap between polyesters and epoxies. Vinyl esters are known for their excellent chemical resistance, particularly to acids and alkalis, as well as good mechanical strength and toughness. They also exhibit superior adhesion to reinforcing materials like fiberglass. The curing process for vinyl ester resins typically involves a peroxide catalyst and an accelerator, which initiates a free-radical polymerization reaction. This reaction creates a highly crosslinked, rigid structure. Common applications for vinyl ester resins include the manufacturing of boat hulls, chemical storage tanks, pipes, and other components requiring resistance to corrosive environments and high structural integrity. Their ease of processing and relatively fast cure times also make them a popular choice in composite manufacturing.
