Product Description

polycarbonate ready to take

Clear polycarbonate granules are a type of high-performance thermoplastic in pellet form, characterized by their natural transparency and exceptional physical properties. They are essentially pure polycarbonate resin, meaning they haven't had colorants or pigments added.

Here's a detailed description:

Chemical Composition: Polycarbonate (PC) is a linear polycarbonic acid ester. The most common type is based on 2,2-bis(4'-hydroxybenzene)propane, also known as bisphenol A (BPA), and phosgene (COCl2). The polymer chains consist of repeating units of carbon, oxygen, and bisphenol A, linked by carbonate groups.

Properties: Clear polycarbonate granules possess a remarkable combination of characteristics that make them highly desirable across various industries:

  • Optical Clarity/Transparency: They are extremely clear, offering light transmission comparable to glass (over 90%). Their amorphous structure gives them excellent optical properties, with a refractive index of approximately 1.584.
  • Exceptional Impact Resistance: This is one of their most significant advantages. Polycarbonate is virtually unbreakable, making it ideal for applications requiring high durability and safety.
  • High Mechanical Strength and Stiffness: They exhibit excellent tensile and flexural strength, making them robust and resistant to deformation.
  • Heat Resistance: Polycarbonate can withstand high temperatures without significant melting or deforming, with a high glass transition temperature (typically 160-200C) and continuous service temperatures up to 100-140C.
  • Dimensional Stability: They maintain their shape and size well, even under stressful conditions.
  • Lightweight: Despite their strength, they are relatively lightweight, which is beneficial for weight reduction in various applications.
  • Electrical Insulation: They are excellent electrical insulators, making them suitable for electronic components.
  • UV Resistance: They generally have good resistance to UV radiation, although additives can further enhance this property for outdoor applications.
  • Recyclability: Polycarbonate is an eco-friendly material that can be processed and recycled.
  • Processability: They are easily moldable using techniques like injection molding, extrusion, blow molding, and thermoforming, allowing for the creation of intricate and durable products.

Disadvantages: While highly advantageous, clear polycarbonate granules do have some drawbacks:

  • Flammability: Without additives, they have limited inherent flame retardancy.
  • Chemical Sensitivity: They can be sensitive to certain chemicals, solvents, and cleaning agents.
  • Scratch Prone: The surface can be prone to scratching.
  • Cost: Polycarbonate can be more expensive than some other common plastics.

Manufacturing Process: The primary methods for producing polycarbonate resin include:

  • Interfacial Polymerization: This involves the reaction of bisphenol A with phosgene in a heterogeneous system (aqueous and organic phases), typically in the presence of an inorganic base and an organic solvent. The polycarbonate product is then separated, purified, and processed into granules.
  • Melt Transesterification: In this process, bisphenols react with diaryl carbonates in the melt, releasing hydroxyarylene. The resulting polycarbonate melt is then processed into granules.

After polymerization, the polycarbonate melt often undergoes cleaning steps (e.g., filtration) and degassing to remove impurities and volatile components before being extruded and cut into granules.

Uses and Applications: The unique properties of clear polycarbonate granules make them indispensable in a vast array of industries:

  • Automotive: Headlight lenses, interior components, sunroofs, face shields, machine guards, helmet visors.
  • Electronics & Electrical: Laptop and tablet casings, smartphone covers, electrical insulators, connectors, LED light covers/diffusers, compact discs (CDs), DVDs, energy meters, switchgear.
  • Construction & Glazing: Safety glass, roofing, skylights, transparent panels, greenhouses, architectural glazing.
  • Safety Equipment: Safety goggles, face shields, helmets, protective gear.
  • Optical Lenses: Eyeglass lenses, camera lenses.
  • Medical Devices: Incubators, surgical instruments, dialysis machines, laboratory safety shields, centrifuge tubes.
  • Consumer Products: Water bottles (BPA-free options available), food containers, domestic appliance housings.
  • Aerospace: Aircraft windows, interior components.
  • Signage and Displays: Outdoor signs, display screens.
  • Sporting Goods: Helmets, protective gear, sports goggles.
  • Prototyping: Used in CNC machines and FDM 3D printers.

In essence, clear polycarbonate granules are a cornerstone material for products that demand a combination of transparency, strength, durability, and heat resistance.
