The authors first outline the basic principles and fundamental foaming mechanisms, covering thermodynamics, kinetics, and the basics of blowing agents and foam formation. Foaming technologies and product applications then become the focus, with explanations of structure-property relationships, processing methods, and general types of foams.

Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyurethanes contain two types of.

The foams have spherical pores, with a small size range, connected by windows, to create an interconnected, open cell structure. Despite the simplicity of the process, the foams have good and reproducible foam structures and compressive mechanical properties, although the ability to vary the pore size and density is by: 1.

Foaming of polymeric materials enables weight reduction, very important from the economic point of view, but most of all, it should be considered as an excellent means to provide new.

1 Material Properties of Plastics Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions.

Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure ). Assuming a starch based material can be found able to replace extruded polystyrene foam, a renewable alternative would be available that strongly reduces the amount of foamed plastics in waste streams.

In this study it is shown that by the foaming of potato starch based expandable beads such Cited by: 2.

To further advance our knowledge of foam structure–property relationships, better investigation of the structures of real solid foams is needed. Foam measurements are generally taken using visual in-spection, photography, or. In this study, we improved the thermal insulation behavior and mechanical properties of extruded polystyrene foams through morphology control with the foam nucleating agent 1,3,5-benzene-trisamide.

Furthermore, the structure–property relationships of extruded polystyrene foams were established.
