Polysulfone

Name:
Polysulfone
Detailed information:
A synthetic thermoplastic polymer.

Properties:

Hard, rigid, transparent solid. Tensile strength 10,000 psi, d 1.24, flexural strength 15,000 psi, good electrical resistance, minimum creep, low expansion coefficient. Soluble in aromatic hydrocarbons, ketones, and chlorinated hydrocarbons; resistant to corrosive acids and alkalies, heat, oxidation, detergents, oils, and alcohols. Dimensionally stable over temperature range −100 to +148C; tends to absorb moisture, readily processed and fabricated. Combustible but self-extinguishing.

Derivation:

Condensation of bisphenol A and dichlorophenyl sulfone.

Use:

Power-tool housings, electrical equipment, extruded pipe and sheet, automotive components, electronic parts, appliances, computer components, base matrix for stereotype printing plates.
