Features & Benefits
Superior Rigidity for Extrusion
PA-747F’s tensile strength (46 MPa) and flexural modulus (1.9 GPa) ensure stable, warp-resistant profiles. Perfect for refrigerator door liners and industrial extrusions that demand precision.
Impact Resistance in Cold Environments
With 30 KJ/m² Izod impact strength (23°C) and 20 KJ/m² at -30°C, this ABS withstands drops and shocks, even in freezer components or outdoor settings.
Heat & Flame Safety Compliance
Vicat softening temperature of 106°C and HB flammability rating (UL 94) ensure reliability in high-heat zones like refrigerator compressors, while meeting global safety standards.
Use & Applications
- Refrigerator Plating: Door liners, handles, and trim with flawless painted finishes.
- Industrial Extrusions: High-strength profiles for machinery, automotive trims, and HVAC systems.
- Safety-Critical Components: Compressor housings and electrical enclosures requiring flame resistance.
