Independent Testing & Evaluation


“The results clearly form a cohesive picture as to the viability of a safe packaging solution for containment of a thermal runaway fire based on intumescent fire resistant polymer composites for operational use, transportation and storage of lithium ion cobalt batteries.”


“It was shown that insulation materials can prevent the probable propagation of thermal runaway in modules constructed with the prismatic cells.”


“As a last line of defense these materials have demonstrated significant potential to limit or halt propagation.”

What makes LithiumPrevent unique?

Fire resistant, a higher degree of fire protection than fire retardant

Highly insulating char which provides a thermal barrier is formed through an endothermic reaction

Electrically insulative (high Dielectric Breakdown strength)

When dealing with lithium battery fire (i.e. class delta fire), this material stays up with rapid rise in temperature by reacting instantaneously

There are several commercially available formulations – what do the different formulations change?

For formulations LP 100R, LP 150 and LP 200, the loading of different additives is varied to increase or decrease the fire performance characteristics and mechanical properties of our materials.

How can you process the material?

For prototyping, we make blocks to size and CNC machine the material. So long as wall thicknesses are 1mm+ we have not had any issues making parts into very complex shapes.

For production, we can injection mold, thermoform or extrude depending on the needs of the design and what is more economical.

Is your material easy to process?

Injection molding, thermoforming and extrusion are all capable of utilizing existing tooling with little parameter changes in most cases but review on a case by case basis is required. Proprietary knowledge of speeds and feeds require trials and experimentation but we have the ability to train and support as needed.
