Thermoplastics foaming

Additives have the same effect on thermoplastic foaming processes as on thermoset foaming processes. Environmental conditions are important in this case because of the necessity of removing heat from the foamed stmcture in order to stabilize it. The dimensions and size of the foamed stmcture are important for the same reason. [Pg.404]

Other minor uses of ethyl chloride iaclude blowiag agents for thermoplastic foam (51) and styrene polymer foam (52), the manufacture of polymeric ketones used as lube oil detergents (53), the manufacture of acetaldehyde (qv) (54), as an aerosol propellent (55), as a refrigerant (R-160), ia the preparation of acid dyes (56), and as a local or general anesthetic (57,58).

The authors of [33] considered their liquid Newtonian. Going back to Fig. 3 and its discussion, it becomes clear that this theory is fully applicable in qualitative and even semiquantitative analysis of thermoplastic foaming. [Pg.109]

Thermoplastic foams - mainly polystyrene, PVC, polyethylene and polypropylene -account for roughly 50% of all plastic foams, the other 50% being polyurethane, a thermoset material. For all uses added together, EPS accounts for more than 90% of all thermoplastic foams, followed by PVC with a few percent, and polyethylene and polypropylene. [Pg.68]

Thermoplastic foaming is obtained by injection of high-pressure gas directly into the melt flow. [Pg.741]

The shaping of the core thermoset and metal cores are generally machinable only. The linear thermoplastic foams are thermoformable. [Pg.750]

Based on microcellular thermoplastic foam technology, the MuCell process uses a blowing agent (typically CO2) that in a supercritical state creates foams with evenly distributed and uniformly sized microscopic cells, 5-50 qm for example. This foam... [Pg.837]
