SABIC LEXAN EX1332T Hot Sale PC Resin

Physical Properties

• Specific Gravity: The specific gravity is 1.20 g/cc, measured according to ASTM D792.
• Density: Measured using injection – molded samples in accordance with ISO 1183 standard, the density is 1.20 g/cc (0.0434 lb/in³).
• Linear Mold Shrinkage, Flow: For injection – molded plaques with a thickness of 3.20 mm, the linear mold shrinkage in the flow direction, determined by the SABIC method, is 0.0050 – 0.0070 cm/cm (0.0050 – 0.0070 in/in).
• Melt Flow: As per ASTM D1238 standards, at a temperature of 300 °C (572 °F) under a load of 1.20 kg (2.65 lb), the melt flow rate is 3.0 g/10 min.

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Modification Features:
  
  • Contains branched polycarbonate resin for enhanced processability.
  • Incorporates release agents for easy extrusion in manufacturing.
  • UV – stabilized to resist degradation from sunlight exposure.

Applications:

LEXAN™ EX1332T is primarily designed for multi-wall sheet and profile extrusion, leveraging its mechanical strength, UV resistance, and optical properties. Below are detailed application areas supported by its properties:

1. Construction and Architecture
   • Multi-Wall Sheets for Roofing and Cladding:
   • Application: Used in roofing panels, skylights, and cladding for commercial and residential buildings.
   • Example: Greenhouses, industrial roofing, and architectural glazing where lightweight, durable, and UV-resistant materials are critical.
2. Signage and Lighting
   • Transparent Signage and Lighting Diffusers:
   • Example: Street signs, retail displays, and LED light diffusers.
3. Industrial Applications
   • Profile Extrusion for Structural Components:
   • Application: Extruded profiles for structural supports, frames, or industrial panels.
   • Example: Frames for industrial machinery enclosures or conveyor system components.

Processing Characteristics

• Extrusion Suitability: The low MVR (3 cm³/10 min) and high viscosity make LEXAN™ EX1332T ideal for extrusion processes, ensuring uniform melt flow and structural integrity in multi-wall sheets and profiles.
• Mold Release: The inclusion of a release agent reduces adhesion to extrusion dies, minimizing defects and improving production efficiency.
• Color Options: Available in transparent, translucent, and opaque colors, allowing customization for aesthetic and functional requirements.

Regulatory and Safety Compliance

• UL94 HB Rating: Meets basic flammability requirements for applications where fire resistance is not the primary concern.
• Regulatory Data Sheet (RDS): Complies with regulations such as RoHS and REACH-SVHC, ensuring environmental and safety compliance.
• Safety Data Sheet (SDS): Available through SABIC’s SDS Portal for detailed handling, storage, and transportation guidelines.

Limitations

• Color Availability: Available in a limited number of colors, which may restrict design flexibility in some applications.
• Flammability: The UL94 HB rating indicates it is not suitable for applications requiring higher fire resistance (e.g., V-0 or V-1 ratings).
• Cost: As a specialized extrusion-grade polycarbonate, it may be more expensive than general-purpose resins, though cost data is not publicly available.
