1 Material Properties of Plastics - Wiley-VCH

1 Material Properties of Plastics 1.1 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 asseling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure 1.1)..

Resource or waste? A perspective of plastics degradation

The cheapest and highest volume synthetic polymer is polyethylene, which worldwide is factory-made on a quantity of 100 million tons per year (Schneiderman and Hillmyer, 2017). HDPE, characterised by its large density to strength ratio and resistance to many different solvents, is frequently recycled.

Foam Manufacturers Suppliers | IQS Directory

Polyethylene foam is made from mixing chemicals and adding a gassing agent, which causes the material to expand. The longer the process and the greater the intensity of the gassing agent, the more porous the foam product will be. The gas bubbles that are trapped inside the polymer make the foam flexible, unlike a solid polymer.
