产品描述
Plexiglas® SG7 is an impact modified acrylic resin suitable for injection molding and extrusion. This grade is formulated for approved medical applications. 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
