Product Description
Plexiglas® SG7 is an impact modified acrylic resin suitable for injection molding and extrusion. It is a high flow resin designed to provide outstanding light transmission and water white clarity for disposable medical applications.

Some of the features and benefits of Plexiglas® SG7 are:

  • Chemical Resistance
    • Good resistance to lipids and drug formulations
    • Good resistance to isopropyl alcohol (IPA)
    • Property retention after exposure to hospital antiseptics, acids and bases

  • Sterilization
    • Stable to gamma radiation, E-beam, and ETO
    • Rapid recovery with excellent color stability
    • Retention of transparency and clarity
    • Retention of mechanical properties

  • Durability and Processability
    • Moldflow simulation data available
    • Excellent melt processability
    • Reduced cycle times
    • Suitable for thin-wall applications and complex multi-cavity molds
    • Good bondability using solvent, ultrasonic, or radio frequency methods
