A flame retardant is used to inhibit the spread of fire on the surface of any material. They are often annexed with surface coatings, finishes, plastics and textiles to furnish flame retarding capabilities to these materials. Flame retardants are nothing but chemicals incorporated to delay the intensive spread of flame upon a surface by controlling the chemical reactions that influence the outspread of fire.
Categories of flame retardants:
Additive flame retardants are type of retardants wherein the essential chemical is mixed with the base material. Mineral flame retardants normally fall under the category of additive flame retardants. On the other hand, sturdy chemical bond is established as in the case of reactive flame retardants. Organophosphorus compounds and organohalogen compounds could be categorized as both reactive and additive flame retardants.
Low smoke zero halogen:
Low smoke free of halogen refers to a material classification used for cable industries. They are advantageous as they emit very less smoke and no halogen whatsoever. The cables used are composed of compounds that are pivotally thermoplastic or thermoset and can withstand heat to a great extent. Over the years, considerable improvements have been made to eliminate all potential degraders to the environment.
LSZH cables in the contemporary era:
Low smoke free halogen minimizes toxicity and the emission of corrosive gas during the process of combustion. In future, low smoke zero halogen incorporated cables will be widely used in nuclear industries. Consequently, the detriment caused due to emission of toxic gases in these industries could be drastically reduced.
Low smoke halogen free flame retardant polypropylenes:
The alarming rise in constructional sites could increase the usage of low smoke halogen free flame retardant polypropylenes. The frequent occurrence of fire mishaps has created the inevitable requirement for resolving and deterring such accidents. Halogen free flame retardant polypropylene is an eminent way to solve such fire accidents as they maintain the VOC levels with better efficacy.
Significance of flame retardant polypropylenes:
Flame retardant polypropylene creates an extra layer to effectively work against fire. The installation of such retardants are not that cost efficient. Hence, the prevalence lags in terms of cost quotient. However, the increase in fire accidents could alter the current scenario and furnish soaring rise in the production of these flame retardant compounds. Industries have started incorporating low smoke halogen free flame retardant polypropylenes to eliminate environmental hazards. Some of the industries that have rampantly implicated in the usage of these retardants include electronics, furniture, labeling, construction, packaging and automotive.
