High‑performance specialty fibers for appliance applications.

We manufacture several high-performance specialty fibers and inorganic materials that are used in appliance applications, including thermal insulators and gaskets for commercial and domestic appliances. Our blankets, fibers, papers and felts, textiles, and vacuum formed shapes have proven success in applications where high heat or potential fire is a problem. Our Fiberfrax® ceramic fiber materials are lightweight, easy to fabricate, and capable of providing protection up to 2300°F (1,260°C). Our Insulfrax® and Isofrax® products are designed with low bio-persistent fiber technology as an alternative to traditional aluminosilicate refractory ceramic fibers, making them an ideal solution for specialty vacuum formed thermal components.

Unifrax Engineered Thermal Components (UETC) materials can be formed as boards, sleeves, combustion chambers and any custom shape. In addition, UETC has a wide range of machining capabilities for added details and tight tolerances.

FyreWrap® LiB Performance Materials are proven to prevent thermal runaway propagation and cascading battery fires within new, emerging lithium-ion battery applications.

Introducing Isofrax 1400 Insulation

Isofrax 1400 thermal insulation is the latest generation of proven, revolutionary low bio-persistent fiber technology from Unifrax.


Silplate Structural Insulating Board

Silplate® boards were specially developed by Unifrax for backup applications that require a very high-strength refractory insulating material. Common applications are for backup in ladles or tundishes that are used in molten metal transfer. Using Silplate boards for backup applications can significantly reduce steel shell cold face temperatures. Because of Silplate’s high use temperature limit, in many cases a thinner refractory cross section may be used and this practice results in increased vessel capacity.
