Compression moulding, cast

It is likely that the quinone methide and related structures formed at these temperatures account for the dark colour of phenolic compression mouldings. It is to be noted that cast phenol-formaldehyde resins, which are hardened at much... 

Force extension curves have revealed an anisotropy of mechanical properties for compression-moulded samples but an isotropy for cast films122. ... 

Various conventional processing technologies, such as casting, extrusion, injection and compression moulding, have been adapted for processing starch-based materials, as well as some new techniques, such as orientation and reactive extrusion. 

After drying for 15 h in vacuo, polyurethanes were compression moulded at temperatures between 100 and 200 C and at a nominal load of either 8 or 12 tons. Biomer" was solvent cast in 3 layers directly from the 30% dimethylacetamide solution supplied and the sheets were dried at 40 C in a flow of dry nitrogen for 7 days. The flat sheets had dimensions of 60 mm x 100 mm and were 1 mm thick. They were cut into several pieces or punched into dumbbells 3 cm in length. The straight (testing) area of the dumbbell was 13 nun x 4 mm. All samples showed no birefringence under cross polarizers, indicating that there was no detectable residual stress.

PLA outer layers and observed that the mechanical properties of the SPI film were improved by lamination with PLA layers, which were comparable to those of low- and high-density polyethylene (LDPE and HOPE, respectively). More recently, Ghanbarzadeh and Oromiehi (2009) prepared bilayer films based on plasticized whey protein films. They also prepared olive oil-plasticized zein films by casting and subsequently laminated them by compression-moulding and discovered that there was an improvement in tensile properties due to favourable interactions between the layers.
