Features & Benefits
High Flow & Impact Balance
POLYLAC PA-757H delivers unmatched melt flow (30 ml/10 min) and Izod impact strength (25 KJ/m²), enabling fast production of thin-walled parts without sacrificing durability. Perfect for reducing cycle times in appliances like vacuum cleaner housings.
Premium Surface Gloss
With its high-gloss finish, ABS PA 757H eliminates the need for secondary painting, cutting costs for visible components like motorcycle fairings or sleek refrigerator panels.
Reliable Thermal Stability
PA-757H withstands heat up to 105°C (Vicat), ensuring parts like hair dryer nozzles or automotive trim retain shape and strength even under prolonged thermal stress.
Use & Applications
- Household Appliances: in thin-walled blender jars or coffee maker housings.
- Motorcycle Parts: from glossy helmet shells to durable side panels.
- Large/Thin-Wall Components: TV bezels or laptop casings.
