Flame retardant PC film is a high-performance plastic film made from Polycarbonate (PC) as the main raw material, after special flame retardant modification treatment. Polycarbonate is an amorphous thermoplastic resin that is widely recognised for its excellent electrical insulation, ductility, stability, chemical resistance and high temperature resistance (the operating temperature range is usually -40℃ to 135℃). Flame retardant PC film is based on maintaining the original excellent characteristics of PC, through the addition of flame retardants or the use of specific flame retardant technology, endowed with the ability to prevent the spread of flame, inhibit combustion, or can be quickly extinguished by itself after the removal of the ignition source, thereby significantly improving the safety performance of the material.
Features
- Flame retardant performance: Flame retardant PC film has excellent flame retardant effect, and can meet the fire safety standards of different applications, such as UL 94 V-0 rating, i.e., in the vertical combustion test, the sample can be quickly self-extinguishing, and the burning droplets will not ignite the cotton underneath the bedding.
- Electrical insulation: as a basic property of PC materials, flame retardant PC film continues to maintain good electrical insulation properties, suitable for electric power systems, electronic equipment, internal insulation and electrical enclosures and other applications that need to prevent current leakage or short circuit.
- Mechanical strength and toughness: high impact strength and tensile strength, even at low temperatures can still maintain good toughness, not easy to brittle rupture, to ensure the structural stability and durability in the process of use.
- Transparency and Optical Properties: Transparent flame retardant PC film has high light transmittance, large refractive index, and clear visual effect, which is suitable for insulated windows, display protection and other fields that have requirements for transparency.
- weathering and UV resistance: good weather aging and UV resistance, long-term exposure to outdoor environments, colour stability, small changes in physical properties, suitable for outdoor electronic equipment, signage and other products protection.
- Processability: easy to thermoforming, cold bending, cutting, printing, laminating and other secondary processing, can meet the needs of a variety of complex shapes and special surface treatment.
Applications
With its unique combination of properties, flame retardant PC film is widely used in many industries, especially in areas with strict requirements for fire protection, insulation, transparency and mechanical strength:
- Electrical and electronic industry: used for power system insulation, disk drive insulation, keyboard insulation, TV/monitor insulation, computer motherboard insulation, and the protection of all kinds of electronic components, electrical appliance housings, switch panels, junction boxes, charger housings and so on.
- Transportation: automotive instrument panels, interior parts, lighting system components, etc., need to be flame retardant and high temperature parts, flame retardant PC film is the ideal choice.
- safety protection: to make protective cover, protective screen, helmet and other personal protective equipment, to provide transparent and visible at the same time to ensure the safety of flame-retardant.
- Architectural decoration: used for architectural light roofs, curtain walls, fireproof partitions, signs and labels, etc., not only to meet the demand for aesthetics, but also in line with the building fire safety regulations.
- Outdoor facilities: due to its strong weather resistance, flame-retardant PC film is also suitable for outdoor billboards, LED display covers, solar panels encapsulation materials.
- Consumer electronic products: such as mobile phones, MP3, MP4 and other portable devices, screen protection film, to provide anti-scratch function at the same time with flame retardant properties, to enhance user safety.
