SABIC LEXAN PC2200R Hot Sale PC Resin

Physical Properties

• Specific Gravity: Measured per ASTM D792, the specific gravity is 1.20 g/cc, a dimensionless value relative to water density.
• Density: Determined by ISO 1183, the density is 1.20 g/cc (0.0434 lb/in³), specifying the material’s mass-to-volume ratio.
• Water Absorption: At 23°C under saturated conditions (ISO 62), water absorption is 0.35%, indicating moderate moisture resistance.
• Moisture Absorption at Equilibrium: Per ASTM D570, equilibrium moisture absorption is 0.35% under standard atmospheric conditions.
• 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 dimensional control in mold design.
• Melt Flow: At 300°C (572°F) under a 1.20 kg (2.65 lb) load, the melt flow rate is 21 cm³/10 min (ISO 1133) or 22 g/10 min (ASTM D1238), reflecting good processability for molding applications.

Polymer Properties:

1. Base Material: Polycarbonate (PC)

Applications:

LEXAN PC2200R’s high flow and balanced properties make it a hot-sale resin for general-purpose molding, where it excels in producing intricate, durable parts. Below are key application areas, supported by property data and industry examples:

1. Automotive Components: Widely used for lighting bezels, headlamp housings, and interior trim due to its impact resistance and thermal stability. 
2. Electrical and Electronics: Employed in enclosures, connectors, and insulators, leveraging its electrical insulation and flame retardancy potential when compounded. 
3. Consumer Goods and Safety Equipment: Suitable for helmets, protective eyewear, and household appliances, thanks to its unnotched Izod impact of “no break” (ISO 180/1U) and water absorption of only 0.35% at equilibrium (ISO 62), ensuring durability in humid environments. 
4. Medical and Optical Devices: Utilized in medical housings and optical lenses due to its biocompatibility potential (when certified) and excellent optical properties typical of LEXAN PC (high light transmittance, though not quantified in this grade’s datasheet). 
5. Building and Construction: Applied in transparent panels, roofing sheets, and signage, benefiting from its weathering resistance and ball pressure test pass at 125°C (IEC 60695-10-2). The CTE stability ensures minimal expansion in outdoor installations.
