Features & Benefits
Safe for Medical Use
Polylac PA-709 ABS resin meets EU 10/2011 standards for low monomer residue and passes ISO10993 biocompatibility tests. This makes it ideal for medical devices like housings or too
High Strength & Durability
With a tensile strength of 40 MPa and Izod impact resistance of 37 kJ/m² (23°C), PA-709 ABS resists cracks and wear. It stays tough even in cold environments (-30°C), perfect for equipment needing long-lasting performance.
Easy to Process Safely
The resin’s melt flow index of 6 ml/10min (220°C) ensures smooth molding. Pre-dry at 80–85°C for 2–4 hours, and mold below 240°C to avoid degradation. Its UL94 HB flammability rating adds safety for electrical or medical parts.
Use & Applications
- Plumbing fittings
- front and rear vehicle spoiler
- motorcycle fenders
- safety helmets
- water filter casings
