Product Introduction: Polystyrene (PS), abbreviated as PS, refers to a polymer synthesized by free radical addition reaction of styrene monomer, with the chemical formula (C8H8) n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. Product name Polystyrene Appearance Colorless and transparent thermoplastic Foreign name Polystyrene Flash point 156.3 Chemical formula C8H8n Melting point 212 Boiling point 293.4 Density 1.05g/cm Classification Ordinary polystyrene/expanded polystyrene, etc Product application: Due to its transparency, excellent rigidity, electrical and printing properties, especially its good hygiene and low cost, polystyrene has broad application prospects in food packaging. It has been widely used in various instrument casings, lampshades, optical parts, instrument parts, transparent window mirrors, transparent models, chemical acid storage tanks, acid conveying tanks, telecommunications parts, high-frequency capacitors, high-frequency insulation pads, brackets, inserts, and frozen insulation materials in the electromechanical industry, instrument and communication equipment industry, etc. It is also widely used in various daily necessities, such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, boxes, and toys.
