Overview
Alcohol-resistant PC is an engineered polycarbonate variant designed to withstand prolonged exposure to ethanol, isopropanol, and other alcohol-based solvents without degradation. Unlike standard PC, it incorporates additives or copolymer structures to enhance chemical stability. The material retains polycarbonate's inherent advantages, including optical clarity (up to 90% light transmission) and high impact resistance (up to 850 J/m by Izod test). Developed primarily for healthcare and laboratory environments, it meets stringent requirements for repeated disinfection cycles. Manufacturers often comply with ISO 10993-1 biocompatibility standards for medical applications. Grades are differentiated by alcohol concentration tolerance (typically 70%–100% ethanol).
Physical and Chemical Properties
The material exhibits a glass transition temperature (Tg) of 145–150°C, maintaining dimensional stability up to 120°C. Its tensile strength ranges from 55–75 MPa, with Rockwell M hardness ~70. Key chemical properties include hydrolysis resistance (pH 4–9) and low solubility in aliphatic hydrocarbons. UV-stabilized versions are available for outdoor use. When exposed to alcohols, surface gloss and mechanical properties show <5% variation after 500 hours of immersion (per ASTM D543 testing). Unlike acrylics, it resolves stress cracking issues common in alcohol-rich environments.
Main Applications
In medical technology, alcohol-resistant PC is used for surgical instrument handles, ventilator components, and transparent protective barriers due to its autoclavability (up to 134°C). Automotive applications include head-up display lenses and fuel system parts where methanol-blended fuels are used. The electronics industry utilizes it for touchscreen covers in devices requiring frequent sanitization. Industrial uses encompass sight glasses for alcohol processing equipment and safety goggles. Emerging applications include 3D-printed dental tools and IVD (in vitro diagnostic) device housings.
Safety and Storage
While non-hazardous under normal conditions, processing above 300°C may release bisphenol A (BPA) traces. Adequate ventilation is recommended during injection molding. Storage should avoid humid environments to prevent moisture absorption (>0.02% weight gain affects processing). Sheets or pellets must be dried at 120°C for 3–4 hours before thermoforming. Regulatory certifications vary by region: USP Class VI and EU 10/2011 compliance are critical for food/medical contact. Material Safety Data Sheets (MSDS) typically classify it as non-flammable (autoignition temperature >450°C).
B2B Procurement Guide
Key specifications to request include alcohol exposure duration limits (e.g., 30-day continuous immersion rating), optical properties (haze <1% for clear grades), and regulatory documentation. For medical use, verify ISO 13485 certification of suppliers. Bulk pricing tiers usually start at 1-ton quantities, with lead times of 2–6 weeks for customized formulations. Sample testing should involve actual solvent exposure simulations. Major global suppliers include Covestro, SABIC, and Mitsubishi Engineering-Plastics. Alternative materials like cyclic olefin copolymer (COC) may be compared for specific chemical resistance needs.
