The growth in the forecast period can be attributed to increasing demand for electric vehicle components, rising adoption of high-performance polymers, expansion of electronics miniaturization trends, growing focus on recyclable engineering plastics, increasing investments in advanced polymer compounding. Major trends in the forecast period include increasing use of pbt in electrical and electronic components, rising demand for lightweight automotive materials, growing adoption of reinforced pbt grades, expansion of injection-molded engineering plastics, enhanced focus on thermal and chemical resistance.

The growing automotive industry is expected to propel the growth of the polybutylene terephthalate (PBT) market going forward. The automotive industry encompasses all companies and activities involved in the manufacturing of motor vehicles, including components such as engines and bodies. Polybutylene terephthalate provides excellent durability under thermal stress and harsh chemical environments, making it particularly suitable for automotive under-the-hood applications. For instance, in October 2025, according to the Institute of Chartered Accountants in England and Wales, a UK-based global professional membership body for chartered accountants, the global automotive manufacturing industry reached a market valuation of USD $2.8 trillion in 2024, reflecting significant recent growth. Therefore, the expansion of the automotive industry is driving the polybutylene terephthalate market.

Major companies operating in the polybutylene terephthalate market are focusing on innovating products, such as polybutylene terephthalate resin, to provide reliable solutions to customers. PBT resin is a thermoplastic engineering polymer with excellent chemical and electrical resistance. For instance, in February 2023, Polyplastics, a Japan-based manufacturer of plastics and polymers, launched DURANEX 201EB. DURANEX 201EB provides electromagnetic wave shielding through electrical conductivity, contributing to reduced assembly work and lower costs. With its PBT resin base, it bonds effectively through double-shot molding and is positioned as an ideal grade for improving the detection accuracy of millimeter-wave radar due to its electrical conductivity and electromagnetic noise absorption properties.

In May 2024, Yazaki Corporation, a Japan-based automotive electrical components supplier, partnered with Toray Industries, Inc., to co-develop advanced lightweight materials for next-generation vehicle applications. This collaboration focuses on developing a recycled PBT resin grade for automotive wire-harness connectors, enhancing sustainability and supporting a circular-economy approach while maintaining performance comparable to virgin PBT. Toray Industries, Inc. is a Japan-based advanced materials and polymer producer, manufacturing high-performance plastics, including PBT, PET, and other engineering polymers for automotive, electronics, and industrial applications.
