What is a styrene monomer (SM CAS 100-42-5)?

Styrene is an organic compound with the chemical formula C₈H₈. The electrons of the vinyl and benzene rings are conjugated. It is insoluble in water, but soluble in ethanol and ether.
A styrene monomer (SM CAS 100-42-5) is a single molecule of styrene. The term 'monomer' means 'one part'. It is the simplest, unlinked form of the chemical capable of chemically bonding with thousands of other identical monomer molecules in a process called polymerisation. This chain reaction forms long-chain molecules called polymers, such as polystyrene. Therefore, a styrene monomer is a liquid building block.

What is styrene monomer SM Used for?

Styrene monomer is an important industrial raw material because it is the chemical 'building block' used to create a variety of versatile plastics and synthetic rubbers with beneficial properties.

SM is typically converted or 'polymerised' into pellets which can be heated, fused and moulded into plastic components.

  • polystyrene (PS)
  • expandable polystyrene (EPS)
  • acrylonitrile butadiene styrene (ABS)
  • styrene butadiene rubber (SBR)
  • unsaturated polyester resins
  • styrene butadiene latices

 

styrene monomer Safety Information:

1. SM (CAS 100-42-5)  is flammable and should be kept away from sources of ignition and high temperatures.

2. Skin contact may cause irritation and allergic reactions; appropriate protective measures should be taken.

3. Long-term or high-dose exposure may have adverse health effects, including damage to the central nervous system, liver, and kidneys.

4. Ensure proper ventilation during use and avoid inhalation or ingestion.

5. Waste disposal must comply with relevant regulations; indiscriminate dumping or discharge is prohibited.
