The Polyethersulfone (PESU) market represents a key segment within the high-performance engineering thermoplastics industry, distinguished by its superior thermal, mechanical, and chemical properties. PESU is a transparent or lightly amber-colored amorphous polymer, a thermoplastic with a relative density of 1.37-1.51, exhibiting over 90% light transmittance and a refractive index of 1.85. It offers excellent thermal stability, high mechanical performance, strong electrical insulation properties, and dimensional stability over a broad temperature range of -100°C to 50°C. PESU maintains its rigidity and mechanical integrity under long-term usage and demonstrates minimal property degradation with increasing temperature. Its chemical resistance is substantial, maintaining stability against inorganic acids, bases, and salts, while showing limited solubility in halogenated hydrocarbons, ketones, and strong acids. The global PESU market is projected to reach a valuation of approximately 250-500 million USD by 2025, with a compound annual growth rate (CAGR) of 7.6%-12.6% through 2030. Market growth is driven by expanding applications across automotive, healthcare, electrical and electronics, membranes, and industrial sectors, where high-performance, durable, and chemically resistant polymers are increasingly demanded.
