Antipyren

   Most polymers have low fire resistance and are flammable. Improvement of fire resistance of polymers is mainly achieved by means of their modification or by introduction of fire retardants (antipyrens) into the material.

   Antipyrens —  are formulations preventing ignition and self-ignition of polymers and other materials of organic origin.

   Fire retardant action of antipyrens is achieved due to the following factors (or combination thereof):

• Low melting point of antipyren with formation of a thin protective layer that prevents oxygen access to the burning material;
• decomposition in heated state with emission of inert gases or vapors which hinder ignition of polymer decomposition gaseous products;
  
• absorption of large amount of heat for antipyren melting, evaporation, and dissociation which prevents impregnated materials from heating to decomposition temperature;
  
• Increased (almost doubled) char formation of impregnated materials due to formation of acids during antipyren thermal decomposition as well as due to decreased quantity of volatizing and combusted carbon and its compounds.

   Conventional commercial antipyrens such as aluminum hydroxide, ammonium polyphosphate are quite efficient. However these antipyrens in high concentrations, which are required to suppress flame, adversely affect physical and mechanical properties of polymers.

Combined plasticizer - antipyren

«FosfAСhim-TT»

Recommendations 

   * Introduction of  5-10%  of this product into paintwork material compositions will impart fire-resistant properties to coating. As an option we offer formulation of an impregnating composition with antiseptic and fire-resistant properties:

   Oxidized oil, viscosity 8-14 min., VZ-4 viscosimeter – 35%

   “ANTSP-3.0”, grade B, antiseptic                             - 1%

   “OctaChim-1.2”  drier                                                 -1 %

   “FosfAChim-TT” antipyren                                         – 5%

   White spirit solvent                                                     -58%

   * amount required is determined empirically for each type of product

Safety measures:

   Storage in tightly closed packaging. Packed product is to be stored in covered storehouse at least 1 m away from heaters
