Title (EN) FINE POLYTETRAFLUOROETHYLENE POWDER AND PRODUCTION AND USES THEREOF
(FR) POUDRE FINE DE POLYTETRAFLUOROETHYLENE, SA FABRICATION ET SON UTILISATION
Abstract:
(EN) A fine polytetrafluoroethylene powder excellent in fluidity in a powdery state, which is composed of fine particles (primary particles) having a mean particle diameter of 0.05 to 1 $g(m)m and has an apparent density of 0.52 to 0.70 g/ml, a standard specific gravity (SSG) of 2.14 to 2.23 and a secondary mean particle diameter of 100 to 1000 $g(m)m; an antidripping agent produced from this powder; a flame-retardant resin composition containing the powder; and an antidusting composition containing the powder.
(FR) L'invention concerne une poudre fine de polytétrafluoroéthylène présentant une excellente fluidité. Cette poudre est constituée de particules fines (particules primaires) ayant un diamètre moyen de 0,05 à 1 $g(m)m, une densité apparente de 0,52 à 0,70 g/ml, un poids volumique standard de 2,14 à 2,23 et un diamètre moyen de particules secondaires de 100 à 1000 $g(m)m. L'invention concerne également un agent anti-suintement réalisé avec cette poudre, une composition de résine ignifuge contenant cette poudre et une composition anti-poussière contenant cette poudre.
