Le PMMA est un verre synth\u00e9tique \u00e0 base de polym\u00e9thacrylate de m\u00e9thyle nomm\u00e9 aussi en usage courant plexi. 7 fois plus r\u00e9sistant que le verre \u00e0 \u00e9paisseur \u00e9gale,
\nce qui le place comme une des mati\u00e8res destin\u00e9es \u00e0 la protection des \u0153uvres : tableaux, cartographies etc…<\/p>\n
On le retrouve sous deux formes, extrud\u00e9 ou coul\u00e9, correspondant aux deux m\u00e9thodes de fabrication.
\nLe PMMA extrud\u00e9 est fondu dans une extrudeuse et pouss\u00e9 dans une fili\u00e8re qui en d\u00e9termine sa forme : plaques, tubes, joncs, etc\u2026
\nIl est moins cher que le PMMA coul\u00e9 mais il offre un peu moins de transmission lumineuse, il est cependant plus pr\u00e9cis en \u00e9paisseur.<\/p>\n
Le PMMA coul\u00e9 est quant \u00e0 lui, fondu entre deux plaques de verre, il est ainsi plus lumineux que le PMMA extrud\u00e9 mais aussi plus cher.<\/p>\n
Les produits nettoyants et les solvants acc\u00e9l\u00e8rent le vieillissement de la mati\u00e8re par apparition de microfissure \u00ab craising \u00bb.
\nC\u2019est pourquoi il est recommand\u00e9 d’utiliser les produits nettoyants des fabricants de mati\u00e8res premi\u00e8res (nettoyant ravivant et antistatique)<\/p>\n
Le PMMA coul\u00e9 est recommand\u00e9 si vous souhaitez coller celui-ci.<\/p>\n
