SABIC LEXAN 143R Hot Sale PC Resin

Physical Properties

• Specific Gravity: As measured by ASTM D792, the specific gravity is 1.20 g/cc, a dimensionless value relative to water density.
• Density: Determined per ASTM D792, the density is 1.19 g/cc (0.0430 lb/in³), specifying the material’s mass-to-volume relationship.
• Water Absorption: At 24 hours per ASTM D570, water absorption is 0.15%, indicating minimal moisture intake under standard conditions.
• Moisture Absorption at Equilibrium: Under ASTM D570, equilibrium moisture absorption is 0.35% at room temperature and 0.58% at 100°C (212°F), showing temperature sensitivity.
• Linear Mold Shrinkage, Flow: Via the SABIC method for 3.20 mm (0.126 in) thickness, flow shrinkage ranges 0.0050–0.0070 cm/cm (in/in), critical for mold design accuracy.
• Melt Flow: As per ASTM D1238 at 300°C (572°F) with a 1.20 kg (2.65 lb) load, the melt flow rate is 10.5 g/10 min, reflecting processability for molding applications.
