Excellent Optical & Weathering Properties: Light transmission up to 89%, haze as low as 0.5%, and UV-resistant grade ensure long-term maintenance of high transparency and color stability, suitable for outdoor lighting.
Good Flame Retardancy: Depending on thickness, achieves UL94 V-2 or HB flame retardant rating, meeting various safety standards.
Outstanding Mechanical Strength: High tensile and flexural strength ensure structural reliability of parts under complex working conditions.
Easy Processing: Low viscosity characteristics suitable for injection molding, with easy-release properties to enhance production efficiency.
Comprehensive Certifications: Complies with UL-746C F1 standard, possesses RTI electrical rating, suitable for automotive electronics and electrical components.
Primary Application Areas
Leveraging its comprehensive performance, Makrolon® PC AL2447 is widely used in multiple industries:
Automotive Lighting: Primarily used for automotive headlamp covers, fog lamp covers, taillight covers, and daytime running light (DRL) covers. Its UV resistance, high-temperature resistance, and high light transmission perfectly meet the stringent weathering and optical requirements for vehicle lamps.
Outdoor & Commercial Lighting: Suitable for street lamp covers, landscape light covers, advertising lightbox panels, and signal lamp covers, capable of long-term resistance to sun and rain while maintaining optical performance.
Electronics & Electrical Components: Can be used for transparent instrument panel covers, switch panels, appliance housings, and optical lenses, balancing aesthetics with flame retardant and insulation needs.
Other Industrial Fields: Such as equipment view windows, safety face shields, transparent parts for medical instruments, etc.
