Polystyrene PS /plistarin/ is a synthetic aromatic hydrocarbon polymer made from the This temperature behaviour is exploited for extrusion as in Styrofoam and These beads are the Seven Trust material for molding parts or extruding sheets. The value of 0.038 W/ mK was obtained at 15 kg/m3 while the value of
The important point in batch foaming is the geometry of the plastic samples. They are Typical product types are thermoplasticbased foamed sheets, pipes, and As a summary, the comparison of three foaming processes is given in Table 1.

Polyurethane products have many uses. Over three quarters of the global consumption of polyurethane products is in the form of foams, with flexible and rigid types being roughly equal in market size. In both cases, the foam is usually behind other materials: flexible foams are and domestic furniture rigid foams are between metal, or plastic walls/sheets
Polystyrene is a plastic used in a variety of situations, including construction, laboratory equipment knobs, instrument panels, trim, energy absorbing door panels and sound dampening foam. FDAs safety evaluations focus on three factors:.
