Product Introduction: DDP flame retardant is an organic phosphorus heterocyclic compound containing two hydroxyl groups. It is a halogen-free reactive flame retardant that complies with the EU RoHS Directive 2011/65/EU standard. It is mainly used for flame retardant treatment of high-end PET, nylon, epoxy resin, polyurethane, unsaturated polyester resin and other polymer materials, making the product have excellent flame retardant effect. Quality indicators: Quality requirements for testing items: Appearance: white powder content of 99% (HPLC), phosphorus content of 8.9%, melting point of 196-1999 ° C, thermal decomposition temperature of 312 ° C, chemical name: [(6-oxo - (6H) - dibenzo - (CE) (1,2) - oxaphosphohexene-6-one) methyl] - succinic acid. Appearance: white powder, low solubility in hydrocarbon and ketone solvents, easily soluble in organic solvents such as DMF and DMSO. Features: High melting point, good thermal stability, non volatile. The synthesized flame-retardant sliced film can be pulled and spun into long fibers, with strong dyeability. After multiple water washes or dry cleaning, the flame-retardant performance does not migrate or decay. It has long-term flame retardant properties, as well as low smoke density, good anti droplet effect, and non-toxic smoke. Application areas: military equipment, electronic appliances, aerospace, rail transit, and other fields. Storage and precautions: Store in a dry, room temperature environment to prevent moisture and heat. Packaging 25kg/bag, paper plastic+inner lining+aluminum foil packaging.
