SABIC LEXAN VR2220 PC Resin

Physical Properties

• Specific Gravity: Tested per ASTM D792, the material’s specific gravity is 1.20 g/cc, indicating its density relative to water.
• Density: In line with ISO 1183, the density measures 1.20 g/cc (0.0434 lb/in³), reflecting consistent mass-to-volume properties.
• Water Absorption: At 23°C/saturated (ISO 62), the material absorbs 0.35%, showing moderate moisture uptake under fully saturated conditions.
• Moisture Absorption at Equilibrium: Per ASTM D570, the equilibrium moisture absorption is 0.35%, suitable for assessing long-term humidity effects.
• Linear Mold Shrinkage, Flow:By SABIC method, for 3.20 mm (0.126 in) thickness, flow-direction shrinkage is 0.0050 – 0.0070 cm/cm (in/in).
• Melt Flow: ISO 1133 records 9.0 g/10 min at 300°C/1.20 kg, while ASTM D1238 shows 10.5 g/10 min under the same testing conditions.

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Modification Features:
  
  • Mid – flow rate enabling efficient injection molding.
  • UV – stabilized to maintain properties under sunlight.
  • Contains mold release for easy part removal from molds.

Applications:

Given these properties, LEXAN™ VR2220 is primarily used in the following applications:

• Medical Device Housings: Its resistance to cleaners makes it an ideal material for the durable housings of patient monitors, infusion pumps, blood glucose meters, and other hospital equipment.
• Connectors and Fluid-Handling Components: The resin is suitable for creating clear, robust connectors and fittings in IV systems, blood oxygenators, and fluid delivery devices.
• Surgical and Diagnostic Instrument Housings: It is used for housings and handles of instruments that require frequent cleaning and resistance to chemicals.
• Diagnostic Equipment: Its chemical resistance and clarity make it a preferred material for parts of laboratory and diagnostic equipment, such as centrifuges and analyzers.
