Trinseo's precursor Styron was formed in August 2009 when Dow Chemical Company combined several of its businesses--styrenics; polycarbonate and compounds & blends; Dow Automotive plastics; emulsion polymers (paper and carpet latex); and synthetic rubber — as part of a larger process of identifying and selling non-strategic assets.
Water-logging commonly occurs over a long period in polystyrene foams that are constantly exposed to high humidity or are continuously immersed in water, such as in hot tub covers, in floating docks, as supplemental flotation under boat seats, and for below-grade exterior building insulation constantly exposed to groundwater.

Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.Its structure consists of a vinyl group as substituent on benzene.Styrene is a colorless, oily liquid, although aged samples can appear yellowish.
The addition of polystyrene to PPE increases the glass transition temperature above 100 °C, owing to the high T g of PPE, so NORYL resin is stable in boiling water. The precise value of the transition depends on the exact composition of the grade used. There is a smooth linear relation between weight content of polystyrene and the T g of the ...
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
Over decades of use, they are now so pervasive that they are detectable in household dust, drinking water, and even our blood. After exposure to the PFAS compounds tested, these 11 genes behaved ...
Expanded polystyrene foam (EPS or "styrofoam", white) is used in making insulation and packaging materials, such as the "peanuts" and molded foam used to cushion fragile products. Polystyrene copolymers are used in the manufacture of toys and product casings.
