Thermal Degradation and Physical-mechanical Properties of Lignin-filled Rigid Polyurethane Foams [PDF]

, 2012
Nowadays, the synthesis of polymers from renewable resources, including polyurethane foams, has been actively investigated. In this work the potential application of lignin (CIMV, France) as non-reactive filler in tall oil amide (OH = 269 mg KOH/g, H2O =

An elasto-visco-plastic model for immortal foams or emulsions [PDF]

, 2007
A variety of complex fluids consist in soft, round objects (foams, emulsions, assemblies of copolymer micelles or of multilamellar vesicles -- also known as onions). Their dense packing induces a slight deviation from their prefered circular or spherical

Natural tannin-based rigid foams as insulation for doors and wall panels

Maderas: Ciencia y Tecnología, 2014
Tannin-based rigid foams were shown to be good thermal insulating materials for use in the cavity of hollow-core wooden doors and other wooden cavities. Their thermal insulation capacity is comparable to that of totally synthetic, oil-derived foams, such
