Insulation - Formex

FORMEX

Formex® polypropylene and polycarbonate insulating material provides excellent electrical shielding for industrial and consumer electronics. It is also useful as a thermal and electrical barrier material. Formex® materials are available in sheet and roll form or can be manufactured in a wide range of shapes to meet flammability and dielectric requirements for a variety of applications.

Why choose Formex® material?

  • Flame retardant to UL 94 V-0 – meeting global standards

  • Non-hygroscopic – Very low moisture absorption

  • Resists chemicals – Maintains mechanical/electrical properties

  • Excellent dielectric insulation – Shields electricity from the electric current

We at EKO-TECH create individual solutions from Formex® material according to the needs of the end customer, in accordance with the technical drawing and other available specifications. In order to obtain the required target product, we rely on an extensive and modern machinery park that allows personalization of the offered product.

The following raw materials are available in our offer:

  • Formex® GS

Formex® GK

Formex® GK is a type of material mainly used in the electrical and electronic industries as electrical insulation. This material is manufactured by ITW Formex®. Formex® GK is a thermoplastic polyethylene material that is flame retardant, flexible, yet strong.

Formex® GK material is used for various applications such as:

  1. Electrical Insulation: Formex® GK is used as an insulator in transformers, power supplies, relays and other electrical equipment.
  2. Structural components: Due to its properties, Formex® GK can be used as a structural element in electronic enclosures and as shields and separators.
  3. Thermal protection: Formex® GK has thermal properties, making it suitable for use as a heat shield to protect sensitive electronic components from overheating.

Formex® GK offers various benefits, such as:

  1. Flame retardant: Meets UL 94V-0 standards, which means the material is flame retardant and does not hold flame.
  2. Mechanical resistance: Formex® GK is resistant to abrasion, tearing and impact, making it a durable material.
  3. Chemical resistance: Formex® GK is resistant to most chemicals, allowing it to be used in a variety of industrial settings.
  4. Ease of processing: The material can be easily cut, stamped and molded, facilitating the process of manufacturing various parts made from it.

Thanks to its properties, Formex® GK has become a popular material in the electrical and electronics industries.

Formex® GS

Formex® GS is a polyethylene-based thermoplastic material produced by ITW Formex. It is widely used in the electronics and electrical industry as electrical insulation and thermal barrier. Like Formex® GK, Formex® GS is characterized by its flame retardancy, flexibility and strength.

Formex® GS has many applications, such as:

  1. Electrical Insulation: Used as an insulator in power supplies, transformers, relays and other electrical equipment.
  2. Structural components: Thanks to its properties, it can be used as a structural element in electronic enclosures and as shields and separators.
  3. Thermal protection: It has thermal properties, allowing it to be used as a thermal shield to protect sensitive electronic components from overheating.

The benefits of using Formex® GS include:

  1. Flame-retardant: Meets UL 94V-0 standards, which means the material is flame-retardant and does not hold flame.
  2. Mechanical resistance: Formex® GS is resistant to abrasion, tearing and impact, making it a durable material.
  3. Chemical resistance: The material is resistant to most chemicals, allowing it to be used in a variety of industrial settings.
  4. Ease of processing: It can be easily cut, stamped and molded, which facilitates the process of manufacturing various parts made from it.

Although Formex® GS and Formex® GK have similar properties, they may differ in some parameters, such as thickness, stiffness or dimensional tolerances. Therefore, it is advisable to check the relevant materials’ technical specifications before using them in a specific project.

Self-adhesive Formex solutions

Self-adhesive Formex solutions are made from Formex, a flame-retardant polypropylene material used in electrical insulation and barrier applications, which come with an adhesive backing for easy application. These solutions are particularly valued in the electronics and electrical engineering sectors for their excellent electrical insulation properties, chemical resistance, and durability. The self-adhesive aspect allows for quicker and more secure installations, providing an efficient way to insulate and protect electrical components, wiring, and assemblies.

Benefits

  • Ease of Application: The self-adhesive backing allows for easy placement and installation without the need for additional adhesives or mechanical fasteners.

  • Customizability: Can be die-cut or shaped into specific sizes and forms to meet the exact requirements of an application.
