Normal FR Grade — Core Product Lineup
What Is Normal FR Grade PET Film?
The Industrial Backbone of Flame Retardant Polyester Technology
Normal FR (Flame Retardant) Grade PET film represents a category of polyester film engineered with inherent or additive-based flame retardancy to meet critical safety standards without compromising on mechanical performance, optical clarity, or processing compatibility. Unlike halogen-containing alternatives, modern Normal FR Grade PET film leverages phosphorus-based or halogen-free additive systems, achieving UL 94 V-0 ratings while remaining environmentally compliant with RoHS, REACH, and EU WEEE directives.
In practical terms, Normal FR Grade refers to a standardized performance tier—balancing cost efficiency with reliable flame-retardant behavior—making it the go-to choice across a broad spectrum of key industrial and commercial applications. From PCB substrate films to display module components, from electrical insulation tapes to photovoltaic backsheets, Normal FR Grade PET film is the unsung material hero in modern technology manufacturing.
At Sichuan EM Technology Co., Ltd. (EMT), Normal FR Grade PET film is produced under stringent ISO 9001 and IATF 16949:2016 quality systems, ensuring batch-to-batch consistency that global OEM partners demand.
Why Normal FR Grade Outperforms in Key Applications
Flame Retardancy
Achieves UL 94 V-0 / V-2 ratings with halogen-free phosphorus systems, ensuring compliance across global safety standards.
Dielectric Strength
High breakdown voltage and low dielectric loss make it ideal for high-frequency PCB, capacitor, and motor insulation applications.
Dimensional Stability
Excellent thermal and mechanical dimensional stability under processing temperatures up to 150°C, critical for precision laminate assembly.
Eco Compliance
RoHS, REACH, and EU WEEE compliant. Halogen-free formulations minimise toxic gas emission during combustion events.
Optical Clarity
Low haze and high transmittance variants available for display module, backlight, and optical film applications requiring pristine light performance.
Commercial & Industrial Trends Driving Normal FR Grade Demand
📱 Consumer Electronics Boom
The global consumer electronics market is projected to exceed $1.1 trillion by 2027. Thinner, lighter, and safer devices demand Normal FR Grade PET films that combine optical precision with stringent flame retardancy for flexible displays, smartphone modules, and wearable sensor arrays.
⚡ New Energy Vehicle Surge
Battery electric vehicles require high-performance insulation in battery packs, motor winding insulation, and BMS (Battery Management System) substrates. Normal FR Grade PET film's thermal stability and UL V-0 rating make it a preferred choice for EV OEM suppliers globally.
🌞 Photovoltaic Expansion
Solar panel installations are growing at a CAGR of 15%+. FR Grade polyester films serve as critical backsheet components, requiring long-term UV resistance, hydrolytic stability, and flame safety certification—all delivered by Normal FR Grade PET specifications.
📡 5G Infrastructure Rollout
5G base stations and millimetre-wave antenna modules demand ultra-low-loss substrate materials. Normal FR Grade PET films with enhanced dielectric properties are increasingly specified in high-frequency PCB constructions for 5G network infrastructure.
🚆 Rail & Aerospace Safety
EN 45545 and FAR 25.853 regulations enforce strict fire safety requirements in rail and aerospace interiors. Normal FR Grade PET films certified under these standards are seeing growing procurement volumes as global transit infrastructure expands.
🏭 Smart Grid & UHV Power
Ultra-high-voltage (UHV) power transmission projects across Asia, Europe, and South America are driving demand for premium insulating films. Normal FR Grade PET film is integral to transformer insulation, capacitor dielectrics, and cable wrapping in smart grid upgrades.
Key Application Scenarios for Normal FR Grade PET Film
Display & Backlight Modules
In LCD and OLED display assemblies, Normal FR Grade PET film is laminated as a diffusion film base, brightness enhancement film (BEF) substrate, or reflective sheet backing. The combination of high transmittance (>92%), low haze (
EV Battery Pack Insulation
Normal FR Grade PET films are die-cut and formed into inter-cell insulation sheets, pouch cell wrapping, and BMS circuit substrates within lithium-ion battery packs. The material's puncture resistance, chemical inertness to electrolytes, and V-0 flame retardancy are non-negotiable requirements for battery safety homologation under UN 38.3, IEC 62133, and GB/T standards.
PV Solar Backsheets
The typical TPT (Tedlar-PET-Tedlar) or TPE backsheet structure uses Normal FR Grade PET as its core structural layer, providing mechanical strength, electrical isolation (>10 kV/mm dielectric strength), and dimensional stability across 25+ years of outdoor exposure. With IEC 61730 and UL 1703 certifications, FR Grade PET from EMT is a trusted component in Tier-1 module manufacturing lines.
PCB & Flexible Electronics
In flexible printed circuits (FPC) and rigid-flex constructions, Normal FR Grade PET serves as coverlay base film and dielectric substrate. Applications span automotive ECUs, medical wearables, industrial HMI panels, and consumer IoT devices where miniaturisation and fire safety coexist as requirements. The primer-coated variants enable superior adhesion with copper foil and solder mask systems.
Electrical Insulation Tapes & Laminates
Motor slot liners, transformer layer insulation, and generator slot wedges utilise Normal FR Grade PET film—often in composite with mica paper or aramid—to achieve class F (155°C) and class H (180°C) insulation ratings. This application directly supports wind turbine generators, industrial motors, and traction motors in rail and EV drivetrains.
Medical Device Packaging
Sterile barrier packaging for Class II and III medical devices requires materials that withstand gamma, EtO, or steam sterilisation while maintaining seal integrity. Normal FR Grade PET meets ISO 11607 requirements and provides the inertness, dimensional stability, and compliance traceability that medical OEMs and contract packagers demand in regulated markets.
