Polyester resin is critical in various industries—from construction and automotive to electronics and marine. As a versatile and cost-effective material, it has become a backbone of manufacturing due to its strong mechanical properties, chemical resistance, and flexibility in molding.
But what exactly is polyester resin? And why is its global market gaining so much attention?
Let’s take a closer look.
Polyester resin is a synthetic material formed through a chemical reaction between acids and alcohols. It's known for its durability, lightweight nature, and affordability. There are two main types: saturated and unsaturated polyester resins.
Its versatility, especially in unsaturated form, makes polyester resin a popular choice for applications that require strength, thermal stability, and corrosion resistance.
According to BCC Research, the global market for polyester resin is expected to grow from $13.0 billion in 2024. It is projected to reach $16.6 billion by the end of 2029 at a compound annual growth rate (CAGR) of 5.0% from 2024 to 2029, driven by increasing demand across the construction, automotive, marine, and electrical industries. As lightweight materials gain importance in manufacturing and infrastructure, polyester resin continues to replace heavier metals and traditional materials.
In addition, innovations in resin formulations—such as low-VOC and bio-based polyester resins—are gaining popularity, supporting sustainability goals worldwide.
