- Melt Flow: Per ASTM D1238, melt flow rate is 7.5 g/10 min at 240°C/5 kg, with moderate flowability for consistent mechanical components.
Polymer Properties:
- Base Material: PC-ABS
- Modification Features:
- Heat resistance suitable for prolonged exposure to elevated temperatures (e.g., 100°C+).
- Flame retardancy (HB rating) meets basic fire safety standards for electronic enclosures.
- Good dimensional stability under thermal cycling for reliable structural applications.
Applications:
The unique combination of properties in TAIRILOY® AC2508 makes it a preferred choice for components in the automotive, electronics, and household appliance industries.
- Automotive Industry
The automotive sector demands materials that offer durability, long-term heat stability, and a high-quality surface finish.
Interior Components: The high heat deflection temperature (104°C) of AC2508 ensures that parts retain their shape and integrity even when exposed to elevated temperatures inside a vehicle, such as in direct sunlight.
- Dashboard and Instrument Panel Components: Resists warping and cracking from heat and provides the necessary rigidity and impact absorption.
- Center Consoles and Trim: Offers a high-quality surface finish that can be easily colored or decorated, along with the durability to withstand daily wear and tear.
- Door Handles and Interior Bezels: The material’s good flowability allows for the molding of intricate designs, while its strength ensures the longevity of these frequently used parts.
Exterior Components (Typically Painted): While pure PC/ABS has limited UV resistance for unpainted exterior use, its excellent impact strength and processability make it a great substrate for painted parts such as:
Mirror Housings: Provides the toughness to resist minor impacts from road debris.
Grilles and Spoilers: The material’s balanced properties allow for complex geometries while maintaining structural integrity.
- Electronics and 3C (Computer, Communication, and Consumer Electronics)
In the fast-paced electronics market, materials must offer precision molding, robust protection for internal components, and compliance with safety standards.
Housings for Electronic Devices: TAIRILOY® AC2508 is widely used for the enclosures of various electronic products.
- Mobile Phone Housings and Brackets: Its high impact strength protects the delicate internal electronics from drops and impacts. The material’s rigidity provides a solid and durable feel to the device.
- Digital Photo Frames, Routers, and Modems: The heat resistance of AC2508 is critical for dissipating the heat generated by internal electronic components, preventing deformation of the housing.
- Laptop and Tablet Casings: Offers a superior balance of toughness, stiffness, and lightweight properties compared to standard ABS.
Office Equipment: The strength and aesthetic qualities of AC2508 are well-suited for the housings of printers, scanners, and projectors. Its dimensional stability ensures a precise fit between parts over the product’s lifespan.
- Household and Electrical Appliances
For household appliances, safety, durability, and aesthetics are paramount. TAIRILOY® AC2508 delivers on all these fronts.
Appliance Housings: The material’s excellent surface finish and colorability allow for aesthetically pleasing designs for products like:
- Vacuum Cleaners: The high impact resistance is crucial for a product that is often bumped into furniture and walls.
- Kitchen Appliances (e.g., Blenders, Coffee Makers): The heat resistance of AC2508 is important for appliances that generate heat during operation.
Housings for Power Tools: Provides the necessary toughness and durability to withstand the rigors of a workshop environment.
Control Knobs and Panels: The good processability allows for the creation of detailed and ergonomic control elements that are also durable.
