CARVALHO, Gil de  e  FROLLINI, Elisabete. Lignin in phenolic foams 66. Polímeros [online]. 1999, vol.9, n.1, pp.66-75. ISSN 0104-1428.  https://doi.org/10.1590/S0104-14281999000100009.

Lignin can be recovered from sugar cane bagasse, which is largely available in Brazil, as a residue from sugar mills. This work presents a new application for lignin-phenol formaldehyde polymers in cellular materials. The foams obtained were characterized by scanning electron microscopy, open cell content, apparent density, compressive strength, hardness. The lignin-phenol-formaldehyde foam presents a thermal insulating characteristics combined with remarkable mechanical properties, which allows its application as structural-thermal insulation foam

Palavras-chave : Lignin; phenolic foam; lignin - phenol - formaldehyde resins; thermal insulation foam.
