Polycarbonate 123

Updated: 2026-07-21

Overview

PC123 is a high-performance polycarbonate grade engineered for industrial applications requiring exceptional mechanical and thermal properties. Developed as a cost-optimized alternative to standard polycarbonates, it retains >85% light transmission while offering improved flow characteristics for injection molding. As an amorphous thermoplastic, PC123 provides inherent dimensional stability and can be compounded with additives for enhanced flame retardancy (UL94 V-0 achievable) or weathering resistance. Its balanced properties make it a preferred material for technical parts where glass-filled polymers are unsuitable.

Physical and Chemical Properties

PC123 exhibits a unique combination of properties including a tensile strength of 55–70 MPa and notched Izod impact resistance exceeding 600 J/m at 23°C. The material maintains functional integrity across a temperature range of -40°C to +135°C, with a heat deflection temperature (HDT) of 130°C at 1.8 MPa. Chemically, PC123 demonstrates excellent resistance to dilute acids, aliphatic hydrocarbons, and alcohols. However, it is susceptible to stress cracking when exposed to certain solvents like acetone or ammonia solutions. The material meets FDA compliance for food contact applications when produced under specific manufacturing protocols.

Main Applications

In the automotive sector, PC123 is extensively used for interior trim components, instrument panels, and headlight lenses due to its vibration damping properties and ability to meet FMVSS-302 flammability standards. The electronics industry employs it for power tool housings, electrical connectors, and LED diffusers where dielectric strength (15–17 kV/mm) is critical. The construction market utilizes PC123 for riot shields, safety glazing, and sound barrier panels, capitalizing on its 250× greater impact resistance than glass. Emerging applications include medical device components and 5G antenna housings, where its low dielectric constant (Dk=2.9 at 1 GHz) proves advantageous.

Safety and Storage

While PC123 is non-toxic in solid form, processing at temperatures above 300°C may release trace amounts of bisphenol A (BPA) vapor. Adequate local exhaust ventilation and personal protective equipment (PPE) including respirators with organic vapor cartridges are recommended during hot processing operations. Pellets should be stored in moisture-proof packaging with desiccant bags to prevent hydrolysis degradation. Opened containers must be resealed and used within 6 months. Processors should predry material at 120°C for 3–4 hours before molding to avoid surface defects. Bulk storage silos should maintain relative humidity below 0.02%.

B2B Procurement Guide

Industrial buyers should specify required certifications such as ISO 10993-1 for medical applications or UL746C for electrical components. Key procurement considerations include minimum order quantities (typically 500 kg for standard grades), lead times (2–6 weeks for custom formulations), and regional availability of specialty variants. For large-volume purchases (20+ metric tons), negotiate pricing based on resin market indices like ICIS PC Europe spot prices. Consider dual-sourcing strategies given global supply chain vulnerabilities – major production hubs exist in Germany, China, and the US. Always request batch-specific technical data sheets (TDS) and material safety data sheets (MSDS) before finalizing orders.
