Electrical insulation films and foils protect electronic devices from electric shock, electromagnetic interference (EMI), electrostatic discharge (ESD), and short circuits. These UL94-approved insulation materials act as dielectric barriers, preventing unwanted electrical currents while providing electrical shielding for sensitive electronics.

Our solutions include insulation films with excellent dielectric strength, high-temperature insulation foils, and flexible insulation films for circuit boards, transformers, motor units, and other critical components. With options like Mylar foil, precision-cut insulation films, and industrial insulation films, we can tailor materials to fit specific requirements.

Your benefits of insulation films

Plastic films are excellent insulators of heat and electrical current. Using the right insulation foil or film offers key advantages:

Meets ESD and other regulations – UL94-compliant insulation materials
Effective electrical insulation – Reliable shielding even in small spaces
Prevents electric shock and interference – Protects sensitive components
Easy to integrate into production – Available as punched and bent insulation parts, adhesive-backed films, and die-cut insulation films

Achieve UL approval for your electronic devices

Using Mekoprint's insulation films is a simple and effective way to meet UL94 safety standards for electronic insulation. We offer high-quality materials designed for reliable electrical protection:

Polycarbonate (UL94 V-0) – Printable material with excellent heat and puncture resistance, low moisture absorption, and strong dielectric strength
Polyester (UL94 V-2) – Lightweight and flexible insulation with low shrinkage, high puncture resistance, and good flame-retardant properties
Polypropylene (UL94 V-0) – High-performance dielectric insulation material with excellent chemical resistance, low moisture absorption, and good heat stability

Our electrical insulation solutions are designed to ensure compliance with regulatory requirements, providing both safety and quality assurance. Whether for medical devices, automotive, or electronics industries, our insulation solutions support the rigorous demands of specialized applications.

Flexible and competitive production

Mekoprint offers a global production setup that ensures cost-effective, high-quality manufacturing:

Global production facilities – Locations in Europe and Asia for best-cost sourcing
Competitive setup – Efficient, scalable production for cost-effective solutions
Die-cutting expertise – Specialists in converting insulation materials into ready-to-use solutions

Versatile applications

Thanks to their dielectric strength, mechanical durability, chemical resistance, and moisture protection, polyester (PET) and polycarbonate (PC) insulation films are widely used in electrical and electronic applications, including:

Motors and generators – as slot liners, wedges, phase insulation to prevent electrical discharge and ensure thermal stability.
Transformers and inductors – as barriers between windings to prevent short circuits.
Printed circuit boards (PCBs) and flexible circuit boards (FCBs) – for dielectric insulation layers, spacers, and protective films in high-density electronic circuits.

Customised electrical insulation solutions

You can customise your insulation materials to your specific needs. Our options include:

Bending to custom shapes – Insulation foils and films shaped to fit any device
Laser-cutting and die-cutting – Precision openings and shapes for easy assembly
Printing – Identification markings, warnings, or branding on insulation materials
Adhesive pads - Easy application and assembly with self-adhesive pads at the back
Molded insulation parts – Specialised insulation for complex device geometries
Enhanced insulation - Conductive paste for extra electrical shielding
Flexible delivery options - Available as rolls, sheets, or individual pieces, with or without adhesive, to streamline your production process.
