Features & Benefits
Superior Chemical Resistance
POLYLAC PA-797 excels in environments exposed to oils, detergents, and cleaning agents. Its chemical endurance ABS formulation prevents degradation, ensuring long-lasting performance for dishwasher components or kitchenware.
Unmatched Impact Strength
With 35 KJ/m² Izod Impact Strength (23°C), this Chimei PA-797 resin withstands drops, shocks, and rough handling. Perfect for appliance housings or tool handles that demand toughness.
Reliable Thermal Stability
It maintains structural integrity up to 105°C Vicat Softening Temperature, ideal for parts near heat sources like microwave panels or coffee maker housings.
Use & Applications
- Blender and Mixer Housings – Withstands impacts and resists grease/oil splatter.
- Refrigerator Interior Parts – Endures repeated exposure to cleaning chemicals.
- Small Appliance Panels – Retains shape under heat (e.g., toasters, air fryers).
- Dishwasher Components – Resists steam and detergent corrosion.
