Reactivity Profile |
An organo-isocyanate. Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. |

General Description |
1,3,5-Tris(2-hydroxyethyl)cyanuric acid (THEIC) is a versatile compound used as a charring agent and modifier in flame-retardant systems. When incorporated into melamine-formaldehyde resin (MFT), it enhances the resin's flexibility, cohesiveness, and flame-retardant efficiency by promoting char formation during combustion. Its hydroxyl groups contribute to improved thermal stability and compatibility with polymers like polypropylene, making it valuable in intumescent flame-retardant applications. Additionally, THEIC synergizes with ammonium polyphosphate (APP) to form a protective char layer, enhancing flame retardancy and water resistance in polymer composites. |
