Dimethyl n-Propylphosphonate (DMPP)
Dimethyl n-propylphosphonate (DMPP) is an organophosphonate flame retardant with superior hydrolytic stability over phosphate esters, used in polyurethane foam, epoxy resins, and coatings. The phosphonate P–C bond resists hydrolysis in humid environments, making it valuable for applications requiring long-term FR durability. DMPP provides primarily gas-phase flame inhibition through phosphorus radical scavenging, and its miscibility with polyols makes it easy to incorporate into two-component polyurethane systems without additional solvent.

Dipentaerythritol (DiPER) High-Char Flame Retardant
Dipentaerythritol (DiPER) is a hexafunctional polyol carbon source used in intumescent flame retardant systems where higher char yields and improved char stability versus mono-pentaerythritol are required. The additional hydroxyl groups and higher molecular weight of DiPER produce a more cross-linked, mechanically robust char that better resists slumping and cracking under fire conditions. DiPER is preferred in high-specification structural steel coatings requiring extended fire resistance periods (90–120 minutes) and thick-film intumescent systems.

Expandable Graphite Flame Retardant
Expandable graphite (EG) is an intercalated graphite compound that undergoes rapid intumescent expansion (50–300x) when heated above 200 °C, forming an insulating worm-like char that physically blocks heat and flame from reaching the underlying material. It is widely used in polyurethane foam, intumescent coatings, sealants, and rubber as a highly effective non-halogen flame retardant. EG is particularly valued for its mechanical intumescent action independent of chemical char-forming reactions, providing reliable fire protection even in non-charring polymers.
