Bisphenol-A-Polycarbonate/ Polycarbonate/ PC CAS 25037-45-0

 

Description:
Polycarbonate is a transparent and amorphous thermoplastic polymer. It is derived from the reaction between bisphenol A (BPA) and phosgene, resulting in a linear chain structure with carbonate linkages. Polycarbonate exhibits excellent impact resistance, high transparency, and good dimensional stability.

Specification:

• Chemical Formula: (C??H??O?)?
• Molecular Weight: Varies depending on the polymer chain length
• Appearance: Transparent solid
• Density: Typically around 1.2-1.22 g/cm³
• Melting Point: Approximately 220-230°C
• Glass Transition Temperature (Tg): Approximately 145-150°C
• Refractive Index: Typically around 1.586-1.588

Application:

1. Engineering Plastics: Polycarbonate is widely used as an engineering plastic due to its exceptional mechanical properties, including high impact resistance, toughness, and dimensional stability. It is employed in the production of automotive parts, electrical components, consumer electronics, and industrial machinery.
2. Optical Applications: The high transparency and optical clarity of polycarbonate make it suitable for applications in optics, such as eyeglass lenses, safety goggles, camera lenses, and optical discs.
3. Construction and Architecture: Polycarbonate is utilized in construction and architecture for applications such as skylights, roofing panels, safety glazing, and transparent walls. Its lightweight nature, impact resistance, and UV stability make it an attractive choice.
4. Electrical and Electronic Components: Due to its excellent electrical insulation properties, polycarbonate is used in electrical and electronic applications, including connectors, sockets, switches, and insulation components.
5. Medical Devices: Polycarbonate is employed in the healthcare sector for medical device manufacturing, such as surgical instruments, drug delivery systems, and diagnostic equipment, thanks to its biocompatibility and sterilizability.

Features:

1. High Impact Resistance: Polycarbonate exhibits exceptional impact resistance, making it suitable for applications that require durability and resistance to breakage or cracks.
2. Transparency: It has excellent optical clarity and transparency, allowing for the transmission of light and making it an ideal choice for applications where visibility is critical.
3. Dimensional Stability: Polycarbonate offers good dimensional stability over a wide temperature range, maintaining its shape and size under varying conditions.
4. Heat Resistance: It has a high heat deflection temperature and can withstand elevated temperatures without significant deformation.
5. UV Stability: Polycarbonate possesses good resistance to ultraviolet (UV) radiation, making it suitable for outdoor applications without significant yellowing or degradation.
