Polycarbonate optical-grade resin

Description

Product Overview
This is a high-purity, optical-grade polycarbonate resin engineered for precision light transmission and impact resistance. It is primarily used in injection molding and extrusion of advanced optical lenses, automotive lighting, and medical device components. The key value proposition lies in its exceptional clarity (92% light transmission) and thermal stability up to 138°C. Strategically, it enables manufacturers to replace glass and lower-grade plastics in high-performance optical systems, reducing weight while maintaining dimensional accuracy—a critical differentiator in the $28B engineered optics market.

Key Specifications & Technical Characteristics

• Chemical composition: Bisphenol A polycarbonate (PC), UV-stabilized additive package

• Purity / Grade: Optical grade, <0.05% haze, no gel or black specks >50µm

• Physical characteristics: Transparent cylindrical pellets; melt flow index (300°C/1.2kg): 10–25 g/10min; density: 1.20 g/cm³; refractive index: 1.586

• Packaging options: 25 kg moisture-barrier bags, 500 kg FIBCs, or 1,000 kg octabins

• Shelf life: 12 months when stored below 40°C / 50% RH in original unopened packaging

Core Industrial Applications

• Primary industries: Automotive lighting, consumer optics, medical diagnostics, AR/VR lenses, safety eyewear

• Operational use cases: Headlamp inner lenses, light guide plates, syringe barrels, patient monitoring housings, spectacle lenses

• Why it performs better: Outperforms acrylic (PMMA) in impact strength (65 kJ/m² vs. 15 kJ/m²) and outperforms standard PC in optical distortion (Δ haze <0.1% after accelerated aging)

• Efficiency/cost advantages: 15% faster cycle times than commodity PC grades; reduces scrap by 30% due to batch-to-batch color consistency (ΔE <0.3)
