The growing need for efficient energy use prompts for effective thermally insulating
materials. Nano‐composites represent an important class of materials able to fulfill these …

This review focuses on the description of the main processes and materials used for the
formulation of rigid polymer foams. Polyurethanes and their derivatives, as well as phenolic …

A natural polyol was prepared from castor oil by alcoholysis with triethanolamine. The oil
and the oil-based polyol were characterized by infrared spectroscopy and through the …

Expandable microspheres/epoxy foams with different densities and microstructures were
prepared by changing the foaming temperature and the precuring extent. The microstructure …

The mechanical impact of adding milled glass fibers and nanoparticles at different mass
fractions to low-density (relative density< 0.2) polyurethane (PU) foams is investigated …

The mechanical behavior of hollow glass microballoon–epoxy matrix syntactic foams
reinforced with carbon nanofibers (CNFs) is studied in this work. Glass microballoons of two …

Syntactic foams are composite materials comprising hollow particles dispersed in a matrix
material. Available studies on high strain rate compressive response of polymer matrix …

This article deals with the synthesis of new bio‐based epoxy foams from the reaction
between cardanol‐derived epoxy compounds and vegetable oil‐derived diamines …

This paper examines the effect of glass fibre reinforcements on the mechanical and
morphological properties of polyurethane rigid foams. The processing parameters of the …

Thermosetting epoxy foams were synthesized by replacing the commercial synthetic epoxy
resin by a biogenic epoxidized vegetable oil. Foam formulations were developed avoiding …
