Formex® Insulators


Formex® Insulator Gaskets are flame retardant products that provide superior electrical insulation and barrier materials for use in industrial and consumer electronic equipment.

Formex® insulators comply with UL 94 V-0, CSA, IEC, VDE, TUV, BSR and METI standards, plus they meet all major North American, European and Asian flammability and environmental requirements, including RoHS and WEEE. The insulating material is available in rolls and sheets, and it can be easily fabricated into a wide range of shapes using our precision cutting services.

Formex® GK, the newest formulation of polypropylene electrical insulation material from Formex®, offers exceptional flexibility and durability for a variety of industrial and consumer product applications. It can be used as a physical barrier that protects general users or service workers from the dangers of exposure to electrically charged components, while safeguarding sensitive electronic elements from damage.

In contrast with fish paper and aramid paper, this electrical insulation material offers superior dielectric strength, an elevated temperature rating, and exceptional moisture and chemical resistance. Formex® GK can easily be scored and folded into three-dimensional shapes, making it a highly versatile product.

Parts fabricated from Formex® are cost-effective replacements for injection molded or sheet metal parts used inside electrical equipment. In these applications, Formex® parts not only are easier to use, they also reduce tooling and fabricating expenses and cut inventory and warehousing costs. Pressure Sensitive Adhesive can also be applied to Formex® products.
