Character

Flame retardant DDP is a white powder with no significant odor. Its solubility in hydrocarbon and ketone solvents is very small, and it is easily soluble in organic solvents such as DMF and DMSO. Flame retardant DDP has a melting point range of 191 to 192 ° C, a flash point of 303.5 ° C, a density of 1.48 g / cm3, and a thermal decomposition temperature above 300 ° C.

Description

Flame retardant DDP is an organophosphorus heterocyclic compound containing two hydroxyl groups. It is a halogen-free reactive flame retardant and meets EU RoHS Directive 2011/65 / EU standards. Because Flame retardant DDP has phosphorus-carbon bonds, it has better flame retardancy than general phosphate esters. Flame retardant DDP is mainly used for flame retardant treatment of high-end PET, nylon, epoxy resin, polyurethane, fiber, plastic, adhesive, unsaturated polyester resin and other polymer materials, so that the product has excellent flame retardant effect.

Features

Flame retardant DDP has the advantages of high melting point, excellent thermal stability, oxidation resistance and water resistance, and is not easily volatile. Synthetic flame retardant chips can be stretched into films and spun filaments, and have strong dyeability. After repeated water washing or dry cleaning, the flame retardant properties do not migrate or decay. Flame retardant DDP has a long-term flame retardant performance, at the same time has the characteristics of low smoke density, good anti-melt drip effect, non-toxic smoke and so on.

Application

Fiber PET is a common polyester. It is widely used as a raw material for synthetic fibers and engineering plastics. However, because of the flammability of polyester materials, the application is limited. Flame retarding modification can improve the flame resistance of polyester. Flame retardant DDP is a new type of flame retardant, which can be used as a copolymerization combination. The modified polyester has hydrolysis resistance, can accelerate the melting drop phenomenon during combustion, and has a flame retardant effect. It has excellent flame retardancy. T30-32, low toxicity, little skin irritation, can be used in automobiles, ships, high-end hotel interior decoration, national defense industry and special labor protection appliances.

Polyester adhesive is added with flame retardant DDP to form a barrier polyester adhesive with good stability, heat resistance, and refractory properties. It can also play a good adhesion role as a solvent.
