Low Smoke and Toxicity
Burning phenolic resin typically generates hydrogen, hydrocarbons, water vapor, and carbon dioxide. Phenolic resin produces a relatively low amount of smoke at a relatively low level of toxicity. Manufacturers use phenolic resins extensively to address the safety concerns of the transportation industry. Automotive and mass transit industries choose phenolic resin for its high heat resistance and excellent flame, smoke, and toxicity properties. Another critical application is in air support systems for the mining industry and related electrical conduit supports. Phenolic resins designed to meet specific flammability ratings are available. Selective use of inorganic fillers and reinforcements often enhances protection in the event of contact with an ignition source.
