Title (EN) PROCESSING AIDS FOR OLEFINIC WEBS, INCLUDING ELECTRET WEBS
(FR) ADJUVANTS DE FABRICATION POUR TOILES OLÉFINIQUES, COMPRENANT DES TOILES D'ÉLECTRET
Abstract: front page image
(EN)Methods of preparing polymeric webs include hot melt blending of thermoplastic resins and processing aids. The process aids include hindered amine N-substituted succinimide oligomers. The webs prepared from the blends may be in the form of films or non-woven fibrous webs. Non-woven microfiber webs are useful as filtration media. Among the polymeric webs produced are electret webs. The processing aids also function as charge-enhancing additives for the electret webs.
(FR)La présente invention concerne des procédés de préparation de toiles polymères qui comprennent le mélange en fusion de résines thermoplastiques et d'adjuvants de fabrication. Les adjuvants de fabrication comprennent des oligomères de succinimide N-substitués de type amine encombrée. Les toiles préparées à partir des mélanges peuvent se trouver sous la forme de films ou de toiles fibreuses non tissées. Les toiles de microfibres non tissées sont utiles en tant que milieu de filtration. Parmi les toiles polymères produites se trouvent des toiles d'électret. Les adjuvants de fabrication servent également d'additifs d'accroissement de charge pour les toiles d'électret.
