Sulphone Polymers are a family of high performance engineering thermoplastic resins characterised by the sulphone group. The aromatic groups, ethers and sulphones which are typical for these polymers provide excellent resistance to hydrolysis and thermal
The size and spatial distribution of these groups prevent the polymer from organising into a semi-crystalline structure. For this reason
polysulphones are amorphous polymers, naturally transparent yellowish (less evident on PSU).
The difference in the chemical structure gives these three polymers slightly different mechanical and thermal properties, as well as chemical resistance.
