    product Advantages

    Improved Flammability Resistance
    The material is designed to be more resistant to ignition and have a slower rate of flame spread when exposed to heat or fire. This helps to delay the propagation of fire. Self-Extinguishing Capability: Fire-retardant polycarbonate sheets are formulated to self-extinguish once the source of ignition is removed, preventing the material from continuing to burn.
    Reduced Smoke and Toxicity
    The composition of fire-retardant polycarbonate minimizes the release of toxic fumes and thick smoke when exposed to fire, improving safety.
    未标题-1 (34)
    Maintenance of Structural Integrity
    These sheets can retain their structural integrity and mechanical properties for a longer duration during a fire, providing more time for evacuation and firefighting.
    Compliance with Fire Safety Codes
    Fire-retardant polycarbonate sheets are commonly used in applications where enhanced fire performance is required to meet building codes and safety standards.

    Production Process

    The production of fire-retardant polycarbonate materials involves a carefully controlled and regulated process to ensure the desired level of flame resistance. This process typically includes the following key steps:

    9b99544edb5253fcf8c5aaa142b0cf5 (2)

    Raw Material Preparation:

    The primary raw materials for fire-retardant polycarbonate production include polycarbonate monomers, such as methyl methacrylate, and various fire-retardant additives.

    The raw materials are carefully selected and measured to achieve the required composition and properties of the final polycarbonate product.


    Polymerization:

    The polycarbonate monomers and fire-retardant additives are subjected to a polymerization process, often using a free-radical initiated method.

    This process involves the use of initiators, catalysts, and controlled temperature and pressure conditions to facilitate the formation of high-molecular-weight polycarbonate polymers.


    Compounding and Extrusion:

    The polymerized polycarbonate material is then compounded with additional fire-retardant additives, such as halogenated compounds, phosphorus-based compounds, or inorganic fillers.

    The compounded material is then fed into an extruder, where it is heated, melted, and homogenized to ensure a uniform distribution of the fire-retardant additives.


    Sheet or Panel Forming:

    The molten, fire-retardant polycarbonate compound is then extruded or cast into sheets or panels of the desired thickness and dimensions.

    This process may involve the use of specialized equipment, such as calendar rolls or casting tables, to achieve the required surface finish and dimensional accuracy.

    test report

    Mclpanel rated to UL 94 HB. Flame Retardant polycarbonate sheet is rated UL 94 V-0 for 90 mils and above and V-2 for 34-89 mils.

    Product advantage

    1. Flame Retardant (UL 94 V-0):

      • Self-extinguishes within 10 seconds after flame source removal

      • No flaming drips that could spread fire to adjacent components

      • Meets IEC 60695-11-10 and GB/T 2408 standards

      • Ideal for battery modules, power supplies, and circuit breakers where fire prevention is mandatory

      Electrical Insulation (High Dielectric Strength):

      • Dielectric strength exceeding 30 kV/mm (depending on thickness)

      • Excellent volume resistivity (>10¹⁵ Ω·cm) prevents current leakage

      • Withstands high voltage stress without electrical breakdown (arc resistance)

      • Maintains insulation properties across temperature range (-40°C to +120°C)

      The Combined Advantage:
      Unlike conventional materials that may sacrifice one property for the other, our PC cover delivers simultaneous flame protection and electrical isolation — ensuring that in the event of overheating or arcing, the material both resists ignition and prevents short circuits. This dual protection makes it the preferred choice for EV battery insulation, PCB barriers, transformer covers, and high-voltage power modules.

    CUSTOM TO SIZE

    1. Cutting:

      • Cutting to Size: Polycarbonate sheets can be cut to the desired size using various methods, such as:
        • Circular saws or table saws with fine-toothed blades designed for plastics
        • CNC (Computer Numerical Control) routers or laser cutters for precise, custom shapes
        • Manual scoring and snapping for simple straight-line cuts
    2. Trimming and Edging:

      • Edge Finishing: The edges of the cut polycarbonate sheets can be finished using techniques like:
        • Grinding or sanding to smooth the edges
        • Applying edge treatments, such as decorative edge moldings or polished edges
    3. Drilling and Punching:

      • Holes and Openings: Polycarbonate sheets can be drilled or punched to create holes, slots, or other openings as required for the application.
      • Specialized drill bits and punches designed for plastics are typically used to prevent cracking or chipping.
    4. Thermoforming:

      • Complex Shapes: Polycarbonate sheets can be thermoformed into various three-dimensional shapes, such as curved or contoured panels, using specialized molds and heating equipment.
      • This process allows for the creation of custom-shaped parts from flat sheets.
