Polycarbonate 703

Updated: 2026-07-19

Overview

PC703 is a high-performance polycarbonate resin recognized for its exceptional mechanical strength, heat resistance, and optical clarity. It is a thermoplastic polymer widely used in industries requiring durable and transparent materials. PC703 is favored for its ability to withstand high-impact forces and extreme temperatures, making it suitable for demanding applications. Polycarbonates like PC703 are synthesized through the polymerization of bisphenol A and phosgene or via a melt transesterification process. The resulting material exhibits a unique combination of properties, including rigidity, transparency, and flame retardancy, which are critical for industrial and consumer applications.

Physical and Chemical Properties

PC703 boasts a density of approximately 1.2 g/cm³, making it lightweight yet robust. Its melting point ranges between 220-230°C, ensuring stability under high-temperature conditions. The material is insoluble in water but can dissolve in certain organic solvents like dichloromethane, which is useful for specific manufacturing processes. Key properties of PC703 include high impact resistance, excellent thermal stability, and good optical clarity. These characteristics make it ideal for applications where durability and transparency are paramount. Additionally, PC703 exhibits low moisture absorption, reducing the risk of dimensional changes in humid environments.

Handling PC703 requires adherence to safety protocols to minimize risks. Workers should wear personal protective equipment (PPE), including gloves and masks, to avoid inhalation of dust or contact with molten material. Proper ventilation is essential during processing to prevent exposure to fumes. Storage conditions for PC703 include keeping the material in a cool, dry place away from direct sunlight to prevent degradation. Moisture-sensitive applications may require additional drying before use. Suppliers typically provide material safety data sheets (MSDS) with detailed handling and storage guidelines.

B2B Procurement Guide

When procuring PC703, businesses should prioritize suppliers with certifications like ISO 9001 to ensure quality consistency. Requesting samples for testing is advisable to verify material properties such as impact strength and thermal stability. Bulk purchases often attract discounts, but buyers should confirm lead times and minimum order quantities. Price ranges for PC703 vary based on quantity and supplier reputation, typically falling between $3-5 per kg. It's crucial to clarify payment terms, delivery schedules, and return policies before finalizing orders. Long-term partnerships with reliable suppliers can secure favorable pricing and consistent material quality.
