Key Problems Solved
Choosing the right Electrical Grade PET Film allows engineers to overcome common manufacturing hurdles:
Eliminating Electrical Breakdown: High-voltage environments require consistent insulation. This film acts as a reliable barrier, ensuring your components pass rigorous safety tests.
Preventing Material Deformation: Thermal processing often causes shrinkage. Our PET Film maintains its shape at 150°C, solving the issue of misaligned layers in FPC or membrane switches.
Reducing Production Rejection Rates: "Fish-eyes" or surface impurities can ruin precision coating. This film is manufactured in clean-room conditions to ensure a flawless surface for die-cutting.
Optimizing Mechanical Support: For flexible circuits, the PET Film provides the necessary stiffness and tensile strength to protect delicate copper traces.
Strategic Applications for Electronics Factories
Our Electrical Grade PET Film is the industry standard for:
Motor & Transformer Insulation: Slot liners and phase-to-phase barriers
Battery Management Systems (BMS): Insulation gaskets and wrapping for EV battery cells
Flexible Printed Circuits (FPC): High-strength stiffeners and base layers
Die-cut Components: Precision-engineered spacers and insulators for laptops and smartphones
By integrating this Electrical Grade PET Film into your supply chain, you ensure batch-to-batch consistency and full compliance with RoHS and REACH directives. We provide this film in various thicknesses with customized slitting services to meet your specific production scale.
Sample & Prototyping Support
Free Sample: Standard A4 size sample free of charge (shipping applies) for your machining tests (cutting, bending)
Fast Prototyping: Standard size prototypes delivered in 2 days, helping you respond swiftly to end-client requests
Stable Bulk Supply & Logistics
Production Capacity: 500,000 kg/month output, reliably handling peak-season large orders.
