Features & Benefits
Exceptional Optical Clarity
TR557 offers high luminous transmittance (90%) and low haze (1.5%), providing crystal-clear visibility for components where aesthetics and display functionality are critical.
Superior Impact Resistance
This material maintains high impact strength (170 J/m at 23°C) even at low temperatures, ensuring product durability and reducing the risk of failure from physical shocks.
Excellent Processing Versatility
With a wide processing window (200-250°C) and good melt flow, TR557 ensures easy molding, high production efficiency, and excellent replication of complex part details.
Use & Applications
- Washing Machine: For transparent lids, detergent dispensers, and control panel covers.
- Refrigerator: For durable and clear vegetable drawers, interior trim, and door handles.
- Electrical/Electronic Products: For protective covers, housings for displays, and transparent structural components.
- Miscellaneous Goods: For a variety of consumer goods requiring a tough, transparent plastic, such as cosmetic cases, office supplies, and home appliances.
