Polysulfone vs. Polyethersulfone: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 1, 2024
Polysulfone is a high-strength, heat-resistant polymer, while polyethersulfone is a similar polymer with enhanced chemical and thermal stability.

Key Differences

Polysulfone is a type of thermoplastic polymer known for its toughness and stability at high temperatures. Polyethersulfone, a related polymer, shares these characteristics but offers even greater heat resistance and chemical stability.
