Halogen-Free Flame Retardant PC Film

Flame Retardant PC Film

Kaixin offers functional film materials with excellent electrical insulation and flame retardant properties, achieving a UL 94 fire rating of V-0 or VTM-0. Our KX-FR7 series flame retardant products meet UL standards while delivering outstanding process adaptability. They resist deformation or cracking during thermoforming, die-cutting, bending, and other processes which enhances product yield rates and ensures dimensional consistency, making them ideal for automated mass production.

KX-FR7 Series Products

KX-FR7C is a transparent extruded film delivering high flame retardancy compliant with UL 94 V-0 standards. Featuring double-side polished surfaces with easily removable protective films, it effectively prevents scratches and contamination during processing, including die-cutting, hot pressing, and printing. Available in standard thicknesses from 250 µm to 500 µm, with custom thickness options upon request. Supplied in both roll and sheet forms to accommodate diverse processing methods.

This material integrates high definition transparency, superior electrical insulation, and robust mechanical toughness. It fulfills following requirements:

Maintaining optical clarity for visual components without compromising display quality

Withstanding high-temperature processing with zero warpage

Compatible with precision thermoforming, laminating, or die-cutting operations.

Its protective film properties significantly reduce scratching and contamination risks while enhancing printing and lamination yields.

Leveraging these advantages, KX-FR7C is extensively utilized in control panel windows for smart home appliances and industrial equipment, transparent insulating barriers within lithium battery modules, intermediate electrical dielectrics in flexible electronics, and protective films for sensors/detection modules. While delivering clear visual transmission, structural protection, and insulation safety, it remains compatible with diverse processes including laser cutting, screen printing, and electronic pattern printing, fully meeting modern electronics manufacturing demands for lightweighting, automation, and stringent safety compliance.

KX-FR7B

KX-FR7B is a UL 94 V0 certified black polycarbonate (PC) flame-retardant film featuring a refined matte velvet surface texture. Combining superior light blocking properties, mechanical strength, and dimensional stability, this product is supplied in roll and sheet formats. Compatible with diverse processing techniques including die-cutting, thermoforming, stamping, and printing, it is engineered specifically for shielding components demanding premium aesthetics, functional performance, and structural integrity.

The core advantages of KX-FR7B lie in its exceptional light blocking and opaque properties, effectively eliminating backlight interference and stray light penetration. Its refined matte surface accommodates secondary processes like spray coating, screen printing, and laser marking. Outstanding impact resistance and thermal deformation control enable reliable performance as high-strength structural supports in confined spaces. As a lightweight solution, it effectively replaces metal or fiberglass composites, delivering electrical insulation while reducing weight in structural applications.

KX-FR7B Series Applications

Leveraging its advanced properties, the KX-FR7B series is extensively deployed across industries:

In communication devices (laptops, routers), it serves as internal structural supports and power module light-blocking barriers, ensuring electrical insulation while optimizing assembly layouts.

For automotive electronics (central control modules, charging systems, functional panels), it functions as structural enclosures and electrical carriers, meeting integrated demands for premium aesthetics, flame retardancy, and precision machining.

Additionally, the material is widely adopted in 5G servers and industrial control systems for power insulation components and signal isolation plates, as well as light-blocking protective films in power battery BMS systems. It maintains exceptional insulation, dimensional stability, and shielding performance under demanding environments, safeguarding system reliability during extended operation.

Application Fields

KX-FR7C and KX-FR7B flame-retardant PC films comply with UL 94 V-0/VTM-0 flame-retardant ratings and meet multiple environmental certifications including RoHS and REACH. They satisfy stringent safety and compliance requirements across electronics, electrical appliances, automotive, and industrial sectors.

Both Materials Feature the Following Advantages:

Superior electrical insulation properties, including high dielectric strength.

Excellent thermal and dimensional stability, maintaining structural integrity and molding precision even in high-temperature environments.
