PC insulation sheet (also known as polycarbonate insulation sheet or PC insulating film) is a high-performance insulating material made from premium polycarbonate (PC) resin, often blended with polyester for enhanced durability. It is processed via precision mold-cutting to meet custom shapes and sizes, catering to diverse industrial needs. Available in common colors like transparent, black, and white (matte white), the thickness ranges from 0.1mm to 0.8mm—flexible enough for complex installations while maintaining structural stability. As a key insulating component, it complies with industry standards (e.g., UL certification) to ensure safety and reliability in electrical and electronic scenarios.
- Superior Insulation Performance: Effectively blocks current conduction, preventing short circuits and electrical leaks—critical for protecting sensitive electronic components.
- Flame Retardant & Fire-Safe: Most models achieve UL94 V-0 or VTM-0 fire ratings, resisting ignition and slowing flame spread to reduce fire risks in devices like power supplies and laptops.
- High Temperature Resistance: Stable operation in a wide temperature range of -40℃ to 120℃; some high-grade variants boast a heat distortion temperature of 135℃-153℃, suitable for high-heat environments (e.g., battery modules).
- Excellent Mechanical Strength: Combines high tensile strength and good toughness, resisting tearing, impact, and deformation during installation or long-term use.
- Corrosion & Chemical Resistance: Unaffected by common industrial chemicals, moisture, and humidity, ensuring long service life even in harsh conditions.
- Versatile Customization: Supports precision mold-cutting into various shapes (e.g., sheets, gaskets, washers) via mold-cut PC insulation sheet processes, adapting to unique product designs.
- Electronic & Electrical Industry: Widely used in laptops, TVs, printers, and power supply shielding (shields) as an electrical insulation PC sheet; acts as a capacitor dielectric (via PC dielectric sheet) to enhance component insulation.
- New Energy Battery Sector: A core material for lithium-ion battery modules and cells—serves as an insulation layer and flame retardant layer in battery PC insulation sheet applications, preventing internal short circuits and improving battery safety.
- Automotive Electronics: Applied in on-board computers, LED lighting systems, and battery management systems (BMS), leveraging its high-temperature resistance and insulation to withstand automotive operating environments.
- Industrial Equipment: Used in motors, transformers, and control panels as a thin insulating barrier (via thin PC insulation sheet), isolating live parts and ensuring equipment compliance with electrical safety standards.
- Consumer Electronics: Integrated into smartphones, tablets, and wearable devices as a compact PC insulation layer, protecting internal circuits while saving space.
