Converting Fiber – Electrical Insulation Materials:

SRP can convert flexible fiber insulation materials such as Nomex, Formex, 3M FRB, 3M ThermaVolt and Insulation Paper to your custom requirements.

Below is a list of fiber materials that we commonly convert in our facilities for customers using these materials for industrial, electrical, automotive, and lighting industries including LED’s.

Thermoseal KLINGERSIL®

KLINGERSIL materials are a range of asbestos-free, calendared sealing materials. Depending on the specific requirements, KLINGERSIL provides excellent resistances (e.g. temperature, mechanical or chemical resistance) in the areas required by the corresponding target industry. Furthermore, KLINGERSIL is easy to cut, handle and fit.

Nomex® Fiber Paper

Nomex provides lightweight, heat and flame-resistant performance for many applications. There’s more than one reason why so many depend on Nomex. Inherently flame resistant, Nomex is three times stronger and offers twice the heat performance versus competitors. Nomex empowers endless possibilities, from design to testing to commercial availability. Nomex delivers reliable performance for increased confidence in the face of many dangerous conditions. Nomex provides proven, lightweight and durable solutions for a range of applications and industries.

3M™ Flame Barrier FRB

The 3M™ Flame Barrier FRB Series is flexible insulation for OEM electrical thermal management applications. The FRB Series products are made primarily of inorganic materials that are intrinsically flame retardant with good dielectric strength. The key features of these products include being an inorganic-based, halogen-free, base material with UL 94 5VA flame rating, has excellent ignitability resistance and excellent arc and track resistance, good dielectric strength, and is dimensionally stable with very low moisture absorption and very low shrinkage at high temperatures. FRB materials are generally lower weight, and more cost-effective compared to similar materials. Typical applications include: general purpose lighting, electric and hybrid electric vehicles, appliances, and electrical devices.

3M™ ThermaVolt Insulation Paper

3M ThermaVolt AR Electrical Insulation Paper combines the best of two technologies – inorganic and aramid – to offer the excellent thermal conductivity and voltage endurance of inorganic insulation plus the strong mechanical and thermal properties you expect of aramid insulation.
