Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a … See more Polystyrene was discovered in 1839 by Eduard Simon, an apothecary from Berlin. From storax, the resin of the Oriental sweetgum tree Liquidambar orientalis, he distilled an oily substance, that he named styrol, now called See more Polystyrene is relatively chemically inert. While it is waterproof and resistant to breakdown by many acids and bases, it is easily attacked by many organic solvents (e.g. it dissolves quickly when exposed to acetone), chlorinated solvents, and aromatic … See more Ordinary (homopolymeric) polystyrene has an excellent property profile about transparency, surface quality and stiffness.

WebFig. 42: Flow in a spiral mould for high-impact polystyrene. Cycle time. A factor that decidedly affects the injection cycle is the time taken for the polystyrene to cool from the melt temperature to the solidification point. The lower this temperature difference, the shorter the cooling time and thus usually also the cycle time. WebAug 4, 2010 · Polystyrene is an amorphous polymer that exhibits high stiffness and good dimensional stability. General-purpose polystyrene (GPPS), also referred to as crystal polystyrene, offers exceptional clarity and rigidity. High-impact polystyrene (HIPS) is made by adding butadiene rubber to styrene during the polymerization process.
