PC WANHUA A1073
WANHUA CLARNATE® PC A1073 – High viscosity, UV-resistant polycarbonate for extrusion and tough, transparent housings; UL 94 V-2 certified at 1.5 mm
Packaging: 25Kg/ Bag
Main features
High viscosity (MFR 7 g/10 min @ 300 °C / 1.2 kg) – enables controlled filling and dimensional stability for sheet/profile extrusion or thick-wall parts.
UV stabilised – helps resist yellowing and property loss in outdoor exposure.
High impact strength – notched Izod ~86 kJ/m² @ 23 °C limits cracking in handling and service.
Optical clarity – ~89% light transmission (3 mm) with haze <0.8% for see-through parts.
Consistent mechanicals – tensile modulus ~2300 MPa supports rigid, precise components.

Typical Applications of WANHUA CLARNATE® PC A1073
• Extruded sheets & profiles – signage covers, machine guards, protective shields (high-viscosity, UV-stabilised grade).
• Outdoor housings & covers – retains appearance and toughness with UV stabilisation.
• Transparent electrical/telecom covers – need clarity with strong impact resistance.
• Injection-moulded clear parts – when rigidity and toughness are required.
Certifications / Standards
• UL 94: V-2 @ 1.5 mm; HB @ 3.0 mm.
• Optical: Haze <0.8%, LT ~89% @ 3 mm.
• General: produced under Wanhua’s CLARNATE® PC programme.
WANHUA CLARNATE® PC A1073 combines outdoor-stable transparency, robust impact strength, and viscosity suitable for extrusion processing—ideal for transparent profiles, covers, and caps that require both aesthetic appeal and durability.
