Intumescent flame retardant

Intumescent flame retardant polymer polymer technology research has opened up a new way, the intumescent flame retardant polymer basic techniques to overcome the traditional shortcomings, has the following advantages: high flame resistance, non-droplet behavior on prolonged or repeated exposure to flame better

Resistance; halogen-free, no antimony oxide; low smoke, low toxic, non-corrosive gases. Intumescent flame retardant main components: 1) the acid source, generally refers to an inorganic acid or when heated in situ combustion acid salts such as phosphoric acid, sulfuric acid, boric acid and phosphate and the like; (2) C

Source, generally refers to more carbon polyol compound, such as pentaerythritol, ethylene glycol, and the phenol resin and the like; (3) foam source, a nitrogen-containing multi-carbon compounds, such as urea, dicyandiamide, polyamide, urea-formaldehyde resin. Intumescent flame study was conducted for the PP has

The majority of commercially available intumescent plastic flame retardant for PP, polyurethane. Phosphorus and nitrogen as the active ingredient together, free of halogen and antimony oxide, phosphorus 21% and 18% of nitrogen. It is flame retardant PP amount of 24% of the oxygen index of 37, flexural modulus increased by 30 to 40%.
