Phenolic resins offer properties like high mechanical strength, long-term thermal and mechanical stability, excellent fire resistance and low smoke and toxicity. They exhibit a glass transition temperature above 150°C. Phenolic resins are mainly used in wood materials, insulating products, and as binders in the building and automotive industries. They are also used in applications that require high thermal stability like friction linings, carbon-carbon composites, and as ablative materials in re-entry vehicles.
