Synthetic structural thermoplastic resin having the properties of high-temperature, arc-resistance, and low-creep. Often used in paint, polish, rubber, and other products.
Polysulfone, or PSU, is a polymer thermoplastic material. It is tough, rigid, high-strength, and transparent, retaining its properties between −100 °C and +150 °C. It has very high dimensional stability; the size change when exposed to boiling water or +150 °C air or steam generally falls below 0.1%.
