FERRO-CHAR

Antimony oxide in combination with halogenated additives has been used in the plastic industry for many years to flame retard plastics. By blending synergists, such as Ferro-Char, the total flame retardant system loading can be effective at lower levels. 

The result cost effectiveness, without reducing performance level. 

Load levels will vary between 3-12%, depending on required result. Only your laboratory testing procedure will determine your proper addition rate. 

Ferro-Char can also be used with glass-reinforced, or solid sphere, MgO, mica, and talc compounds. 

Application ranges are broad, thermoplastics, PVC, urethane and other polymeric materials including adhesives, epoxies, and rubber compounds.

Other markets for char include iron, steel, and sili-con/ferro-silicon industries. Char can be used as a reducing agent in direct reduction of iron. Ferro-silicon and metallurgical-grade silicon metal are produced carbothermally in electric furnaces. Silica is mixed with coke, either iron ore or scrap steel (in the case of ferro-silicon), and sawdust or charcoal in order to form a charge. The charge is then processed by the furnace to create the desired product. Char can be substituted for the coke as a source of reducing carbon for this process. Some plants in Norway are known to have used coal-char in the production of silicon-based metal products as late as mid-1990.5 The use of char in this industry is not practiced due to lack of char supply.
