Polyester is a thermosetting resin matrix system and among the most used in the composites industry. It's most often used in sheet molding compound, bulk molding compound and with glass fiber in industrial, construction, infrastructure and other applications.
There’s more to TP polyesters than you think. You may know PET, PBT, and PETG—but what about PCT, PCTG, PCTA, and PTT? If you’re not sure what they are, how their properties compare, and who sells them, we have the answers—and lots of new developments to report.

Ashland's new Arotran 771 sheet molding compound (SMC) offers a specific gravity of 1.2, with good mechanical and physical properties. The company is targeting 1.0 specific gravity, which would put SMC on par with aluminum in automotive applications.Pultrusions provide composite thermal break CompositesWorld

In 2009, the International Building Code’s new Subsection 12 approved the use of fiber-reinforced polymer (FRP) composites as alternatives for conventional materials used in commercial building envelopes. In 2015, composites advocates saw convincing evidence that those alternatives could be realized in practical, cost-effective applications.Disruptive composite infrastructure CompositesWorld

Aging infrastructure offers a potentially huge market for composite materials but civil projects are publicly owned, subject to regulatory oversight and, therefore, decision makers are change-resistant and decisions are, in part, cost-driven. Composites nevertheless continue to make headway.
