SABIC LEXAN FR 945U PC Resin

Physical Properties

• Specific Gravity: Tested according to ASTM D792, the specific gravity of the material is determined to be 1.19 g/cc.
• Linear Mold Shrinkage, Flow: By the SABIC method, for 3.20 mm thick samples, linear mold shrinkage in flow direction is 0.0060 – 0.0080 cm/cm.
• Melt Flow: As per ASTM D1238, at a temperature of 300 °C (572 °F) under a load of 1.20 kg (2.65 lb), the melt flow rate is 10 g/10 min.

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Key Characteristics:
  
  • Excellent Flame Retardancy: Achieves V-0 rating at 1.5 mm, self-extinguishing within 10 seconds without dripping, ideal for safe electronic components and housings.
  • UV Stabilization: Contains UV stabilizer to resist degradation and discoloration, ensuring durability in indoor and outdoor applications.
  • Good Mechanical Properties: Offers high impact strength, rigidity, and dimensional stability for durable, stress-resistant parts.
  • Opaque Color: Opaque finish conceals internal components, suitable for housings and covers.

Applications:

Given these properties, LEXAN™ FR 945U is primarily used in the following applications:

• Electrical and Electronic Housings: The high V-0 flammability rating makes it an ideal material for enclosures for electronic devices, power supplies, and electrical components.
• IT and Telecommunications Equipment: It is used for housings for servers, routers, and other network equipment where fire safety regulations are strict.
• Industrial and Commercial Equipment: The resin is suitable for housings for control panels, junction boxes, and other industrial equipment where both durability and flame retardancy are required.
• Appliance Parts: It can be used for internal and external parts of household appliances, where it contributes to overall product safety.
