Record 4 1999-02-10

English

Subject field(s)
  • Plastic Materials
DEF

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, to heat and oxidation, and to detergents, oils, and alcohols. Dimensionally stable over temperature range -100 to +148°C; tends to absorb moisture, readily processed and fabricated. Combustible but self-extinguishing. Derivation: Condensation of bis-phenol A and dichlorophenyl sulfone. Use: Power-tool housings, electrical equipment, extruded pipe and sheet, auto components, electronic parts, appliances, computer components, base matrix for stereotype printing plates.

DEF

Nom générique des polymères renfermant dans leurs chaînes des fonctions sulfone.

CONT

Une polysulfone domine largement les autres : [...] d'où le nom de polyéthers sulfones quelquefois donné à ces composés. La préparation la plus courante consiste à polycondenser le bisphénolate de sodium avec la p,p'-dichlorodiphénylsulfone. Les polysulfones sont des thermoplastiques possédant de très bonnes propriétés mécaniques (ténacité, rigidité, tenue au fluage), encore améliorées par additions de charges (fibres de verre ou de carbone), et peuvent être employées en continu entre -70 et 180 °C. Leurs résistances au choc, au feu, leurs propriétés électriques sont très bonnes. Elles ont une bonne résistance chimique, mais se dissolvent dans un certain nombre de solvants polaires. Les polysulfones sont mises en forme par injection et par extrusion. Les plaques peuvent être usinées, soudées, décorées, métallisées sous vide.

CONT

Le terme polysulfone recouvre en fait trois produits très proches en performances mais dont la principale différence est la tenue en température. 1.1. Le polysulfone (PSU) obtenu par réaction de substitution entre le sulfone 4,4-dichlorodiphényle et le sel disodique de bisphénol A. Sa résistance en température est de 150 °C. 1.2 Le polyéthersulfone (PESU) [...] 1.3. Le polyphénylsulfone (PPSU) [...]

OBS

Polysulfone est du genre «féminin» dans les sources LAROG et BOSMA et du genre «masculin» dans l'AFNOR-44 et le ERENGA.

Record 5 1997-06-03

English

Subject field(s)
  • Plastic Materials
CONT

Polyaryl sulfone offers the unique combination of thermoplasticity and retention of structurally useful properties at 500°. This material is supplied in both pellet and powder form. Its thermoplastic nature allows it to be fabricated by injection molding or extrusion techniques on standard commercially available equipment. Polyaryl sulfone consists mainly of phenyl and biphenyl groups linked by thermally stable ether and sulfone groups. It is distinguished from polysulfone polymers by the absence of aliphatic groups, which are liable to oxidative attack. This aromatic structure gives it excellent resistance to oxidative degradation and accounts for its retention of mechanical properties at high temperatures.

CONT

Polyaryl sulfone. A strong, hard, stiff plastic which can be used from -400 to +500°F, this polymer is used mostly in aerospace applications. ... This plastic is often used to upgrade other plastic applications with respect to temperature and to replace metals and ceramics in valve bodies, hydraulic seals, and bearings.

CONT

Poly(aryl sulfone) was introduced in 1983 and is available from Amoco Performance Products under the trade names Radel A-100, A-200, and A-300. It is suitable for high technology applications, including such electrical/electronic parts as printed-circuit boards, snap-fit connectors, and lamp housings.
