GrafGuard® Expandable Graphite Systems Help Meet ASTM E-84 Testing Requirements

ASTM E-84 is the standard test method for assessing the surface burning characteristics of building products. A new white paper from NeoGraf Solutions, “GrafGuard® Expandable Graphite Systems Help Meet ASTM E-84 Testing Requirements” discusses how GrafGuard® expandable graphite expands into a charred intumescent foam when exposed to the heat or flame, protecting the substrate and helping to pass the ASTM E-84 requirements. Minimizing both the smoke development and flame spread maximizes the potential flame spread index classification of the material. [...]Learn More

Bringing the Thermal Management Methods of Consumer Electronics to Transportation Batteries Using SpreaderShield™ Flexible Graphite

In many early battery-powered electric vehicles, cell temperatures were controlled by aluminum. It was a time-tested thermal management material and it could take on some of the structural duties of the battery pack. Battery pack designers recognized aluminum’s drawbacks and began looking for alternative thermal management materials. To spread the same amount of heat as an aluminum plate, NeoGraf Solutions’ SpreaderShield™ flexible graphite is only half of the thickness and one-third of the weight. […..] Learn More

GrafGuard® Expandable Graphite: A Safer Choice for Fire Protection

Protecting people and property from fire is crucial, and fire retardants play a vital role in achieving this goal. While various fire retardants exist, melamine-based options raise concerns due to their EU classification as substances of very high concern (SVHC) in the REACH regulations. GrafGuard® expandable graphite from NeoGraf Solutions is a safe and effective replacement for melamine-based fire retardants […..]Learn More

High-Performance Graphite Thermal Management Solutions Increase Battery Performance

In order for battery powered transportation to become fully viable in the near future, energy density of the battery pack must increase. The optimal solution is to use large surface area pouch cell batteries packed tightly together to form highly energy dense modules. NeoGraf Solutions’ has produced a new video that shows unique an-isotropic arrangement of the high conductivity graphene layers in their SpreaderShield™ graphite. It illustrates how the material prevents battery hot spots, maintaining allowable temperatures and restricts transferring the heat to adjacent battery cells with the thinnest and lightest form-factor possible.

Thermal Propagation Control Strategies in the Electric Vehicle Industry Using SpreaderShield™ Flexible Graphite

When it comes to safety in an Electric Vehicle (EV), the most important aspect is controlling the massive amount of energy stored in the battery pack. To help with this, significant advances have been made in cell design and battery management systems (BMS). However, even with these advances, the possibility of a single-cell failure is always present. SpreaderShield™ flexible graphite heat spreaders are often used as the thermal management material in high-performance battery packs where a small and lightweight form factor is desirable.
