Polyacrylonitrile (PAN)

Polyacrylonitrile (PAN) is a synthetic resin prepared by the polymerization of acrylonitrile. It is a member of the acrylic resin family and is a hard, rigid thermoplastic material.

Properties of Polyacrylonitrile:

• Thermoplastic: Polyacrylonitrile is thermoplastic, which can be melted and remolded under certain conditions.
  Resistance to Solvents and Chemicals: PAN is a durable material resistant to most solvents and chemicals.
• Low Permeability to Gases: Polyacrylonitrile has low permeability to gases, making it useful in applications requiring gas barrier properties.
  High Melting Point: The melting point of PAN is above 300°C, but it degrades before melting under normal conditions.

Applications of Polyacrylonitrile:

Carbon Fiber Precursor: PAN is a precursor for producing carbon fibers. The fibers are heated and carbonized to create solid and lightweight materials used in the aerospace and automotive industries.
