Fyrebloc® Blends

Great Lakes Fyrebloc® flame retardant concentrates and granules are examples of how we use a solution-based approach to meet customer needs. Fyreblocs are low to non-dusting forms of flame retardants.  These products are cleaner, easier and safer to handle, and offer an alternative physical form to powders and liquids.

Fyrebloc® Concentrates are highly loaded flame retardant and synergist systems dispersed in a polymer carrier and compounded into a non-dusting pellet form. Typical loading levels range from 60% to 90% active flame retardant.

Fyrebloc® Granules are 90% to 100% active flame retardant and synergist systems. They utilize an active melt blendable flame retardant and/or a small amount of low melt point wax type binder to form a low to non-dusting granule form.

Fyrebloc® Blends are 100% active flame retardants and synergist systems in a powder form. They provide a simple one-additive package solution to flame retardancy requirements. These products are available in a range of different packaging options, including low melt point inclusion bags.

Standard or Customer Specific

All the Fyrebloc® products are available in both standard and customized formulations. In addition other polymer additives such as stabilizers, process aids and impact modifiers can be included on request.
