Styrene CAS 100-42-5

1. Styrene CAS 100-42-5 is a key monomer used to produce polystyrene (PS) for packaging, disposable tableware, and CD boxes .
2. Styrene is copolymerized to create acrylonitrile-butadiene-styrene (ABS) for automotive parts, electronics housings, and toys .
3. Styrene is also used to manufacture styrene-butadiene rubber (SBR) for car tyres and adhesives, as well as unsaturated polyester resins .

1. Store Styrene CAS 100-42-5 in a tightly sealed container in a cool, well-ventilated area below 30°C, away from heat, sparks, and open flames .
2. Keep Styrene strictly separated from strong oxidizing agents, acids, and peroxides to prevent violent polymerization and fire hazards .
3. Handle Styrene using appropriate personal protective equipment including chemical-resistant gloves and safety goggles, and use only in areas with explosion-proof equipment .

1. Isolate the spill area immediately (500 m or more), eliminate all ignition sources, and evacuate non-essential personnel .
2. Contain liquid Styrene using dry inert absorbent material like sand or activated carbon, prevent entry into drains or waterways, and use non-sparking tools for collection .
3. Personnel cleaning Styrene spills must wear full protective equipment including self-contained breathing apparatus and chemical-resistant suits, and dispose of waste according to hazardous material regulations.

1. Styrene CAS 100-42-5 is a flammable liquid and vapor causing skin and serious eye irritation (H315, H319), and is harmful if inhaled (H332) .
2. Styrene is suspected of damaging the unborn child (H361d), causes damage to hearing organs through prolonged exposure (H372), and may be fatal if swallowed and enters airways (H304) .
3. Styrene is classified by IARC as possibly carcinogenic to humans , is harmful to aquatic life with long-lasting effects (H412) , and has an occupational exposure limit of 50 mg/m³ (PC-TWA) .
