PHENOLICS EXCELLENT FIRE RETARDANCE LOW SMOKE & TOXICITY EMISSIONS
{"Image DocumentName": "PHENOLICS EXCELLENT FIRE RETARDANCE LOW SMOKE & TOXICITY EMISSIONS", "Image ImageDescription": "HIGH STRENGTH AT HIGH TEMPERATURES. MAJOR USES: Mass Transit - Fire Resistance & High Temperature. Ducting. Phenolics are experiencing a resurgence of interest in composites because of their fire resistance. They have low creep and good dimensional stability. Phenolic resins should be considered when the goal is performance under heat, retention of properties under fire conditions or low emission of toxic fumes. Characteristics of phenolics include low flammability, low spread of flame and little smoke. Mechanical properties are comparable to orthophthalic polyesters. Low shrinkage compared with polyesters is as characteristic of this resin. Phenolics are available in liquid form or as molding compounds. Cure at room temperature is possible, however an elevated post cure above 800C is needed ot obtain dimensionally stable materials. Development efforts by the resin producers have resulted in liquid systems for filament winding, pultrusion, and spray-up. This has greatly broadened the market opportunity for phenolics in the composites industry. Their excellent ablative characteristics have been used in rocket nozzle applications.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
