electrical insulation materials

Electrical insulating materials have high resistance to electrical currents. Insulators protect users from the harmful effects of electrical shock, acting as a protective coating for everything from wires and cables to power systems and electrical appliances.

At American Micro Industries, we carry a diverse selection of in-stock and custom electrical insulation sheet materials that will help you safeguard all your vital electrical equipment. Our precision machines and computer-aided design (CAD) models enable us to transform numerous high-quality materials into custom parts for any industry.

Electrical Insulator Materials We Cut

Our electrical insulating material selection is optimized for high dielectric strength and resistivity, providing exceptional opposition against electrical currents and stress that can cause short-circuiting and burn hazards.

As the experts in die cutting and electrical insulation fabrication, American Micro Industries has the machining capabilities to manufacture numerous materials according to military specifications. We offer everything from tube and sheet to rod-stock materials for your insulation needs.

G10/FR4

G10/FR4, also known as Micarta and Bakelite, is a thermosetting laminate material comprising a continuous filament glass-cloth structure and epoxy resin binder. This product provides excellent dimensional stability, insulation properties and resistance to moisture and electrical currents.

We carry G10/FR4 in 36-by-48-inch sheets and offer custom die cutting and computer numerical control (CNC) machining services for this insulation material.

Fish Paper

Fish paper refers to the electrical grade of vulcanized fiber. This fibrous die cut insulation material possesses a unique balance of remarkable strength and lightweight characteristics, making it easy to form and perforate. Unlike other die cut products, fish paper is highly resistant to extreme temperatures. Its distinctive qualities make it a popular material for a wide range of specialized applications.

You can purchase fish paper sheets with or without pressure-sensitive adhesive, depending on your product development needs.

Polyester Film

Polyester film, or biaxially oriented polyethylene terephthalate (BoPET), is an electrical insulation sheet material with high tensile strength, moisture resistance and dimensional stability. This material boasts high strength and durability, making it suitable for heavy-duty applications.

We sell this die cut polyester film in 20-by-50-inch sheets available with or without the pressure-sensitive adhesive. You can also request custom parts die cut to your exact specifications.

VHR-115

VHR-115 is a dense, rigid insulator comprised of acrylic polymer and unbleached kraft pulp makeup. This material features many benefits, such as efficient dielectric and mechanical properties and a low water absorption rate. Its high insulation characteristics make it suitable for products such as coils, transformers, motors and electrical hardware.

You can purchase VHR-115 in sheets with or without a pressure adhesive, or we'll work with you to manufacture custom laser or die cut parts and components to suit your needs.

E-FR

E-FR is an electrical insulator made of unbleached kraft pulp with exceptional mechanical strength. Unlike less sturdy materials such as fish paper, E-FR is highly flexible for easy, break-resistant folding and perforation. It is commonly used as a flame retardant and insulator for electrical parts and components.

You can contact us for custom die cutting services for your E-FR machining project or select our in-stock sheet material with or without the pressure sensitive adhesive.

TRYMER® Machining

TRYMER® is a highly efficient insulating material made from rigid polyisocyanurate. This lightweight electrical insulator offers impressive moisture resistance and high compressive strength. It is optimized for a wide range of commercial and industrial applications, such as refrigeration, construction and tank insulation.

Our broad selection of TRYMER® products comes in various compressive strengths and densities. Our machinists can use specialized CNC machining methods to cut individual TRYMER® sheets in your desired size.
