E-Glass-650 provides heat barrier protection by utilizing a .0315” thick plain weave, proprietary-coated woven fiberglass fabric to shield components from extreme high temperatures and provide thermal stability. Heat shielding materials are commonly used throughout the automotive industry in various applications. For instance, to protect critical engine wiring, prevent vapor lock, and improve vehicle efficiency by blocking radiant heat caused by temperatures under the hood. Heat shielding is also ideal for components near extremely hot engine exhaust systems.

E-Glass-650 has an operational temperature range of 1202°F (650°C); can handle intermittent temperature spikes up to 1292°F (700°C).
