Opinions

What is driving the price gap between PSU, PPSU, and PES resins in China?

Watch feedstock costs too. Benzene prices jumped 18.8% in 2026, directly lifting bisphenol A and diphenyl sulfone costs. Since polysulfone makers pass through raw material swings with a lag, buyers should track upstream aromatics before locking in quarterly contracts.

How is China's polysulfone supply-demand balance shifting through 2025?

The 25,000 tons of new capacity is nearly double current domestic demand. Oversupply risk is real for standard PSU grades by 2025-2026. But don't expect uniform price drops—specialty grades for blood dialysis membranes and baby bottles will keep premium pricing due to certification barriers.

Overview

Polysulfone resin (PSU, CAS 25135-51-7) is a transparent, light-amber thermoplastic with a density of 1.24 g/mL at 25°C and a melting point of 185°C. It is a high-performance engineering plastic known for toughness, thermal stability, and resistance to hydrolysis, acids, alkalis, and radiation.

Medical: used in FDA-recognized devices and components requiring steam sterilization and biocompatibility.
Food & water: complies with NSF standards for drinking-water contact up to 180°F.
Industrial: applied in electrical insulation, aerospace parts, and high-temperature mechanical components.
Consumer: serves as an advanced substitute for polycarbonate in demanding applications.

China's production landscape is expanding, with domestic manufacturers building large-scale capacity for PSU, PES, and PPSU grades. The market is driven by import substitution in medical, filtration, and automotive sectors, while global leaders like BASF, Solvay, and Sumitomo still dominate high-end supply.

Key domestic producers:
Shandong Haoran Special Plastics – diversified polysulfone grades.
Jiangmen Youju New Materials – specialty PSU and PPSU products.
Jida Special Plastics – engineering-grade polysulfone resins.
Shandong Jinlan Specialty Polymers – high-performance polysulfone materials.
Kingfa Science & Technology – export-oriented polysulfone capacity.
