Flame retardancy mechanisms According to their specific mechanisms, fire retardants interrupt polymer pyrolysis in one or more steps. Three of the most common flame retardancy mechanisms are described in previous studies. Gas phase inhibition mechanism, where the FRs react with the polymer under combustion in the gas phase with hydroxyl or oxygen agents at the molecular level and extinguish the combustio…

Flame retardant is indispensable In order to meet fire safety requirements and diminish fire hazards, different solutions have been developed. Various chemical and physical strategies have evolved to prevent polymers from burning or to lower the heat release amount. Recently, flame retardants (FRs) have been widely recognized as fire safety tools capable of lowering the number of fire injuries and death. The t…

Effects of Flame Retardant and Glass Fiber on the Properties of PA66 Due to the needs of electronic product applications, PA66 must have certain flame retardancy and relative tracking index (CTI) properties. Also, depending on product strength requirements, it may be necessary to add glass fibers to the PA66 material. Commonly used flame retardants are nitrogen flame retardants, bromine flame retardants and red phosphorus. (1) Under normal circ…

Common mistakes in the use of flame retardants Misunderstanding 1: The larger the amount of flame retardant, the better the flame retardant effect. The limiting oxygen index (LOI) and UL-94 test results show that the flame retardant performance of the material is related to the flame retardant dosage. With the increase of flame retardant content, the flame retardant effect first increases and then decreases. Too much flame r…

Different Products Require Different Chemical Compounds Not all flame retardants are the same. Plastics and other materials where flame retardants are used are widely different in their inherent properties and in roles they serve in their products. Similarly, flame retardants are a widely diverse set of chemicals that vary by functionality and application. They all help to inhibit or suppress fire ignition — no ignition, no fire. Sp…

Flame Retardant Furniture and Vehicle Preventing fires and extending escape time are of utmost importance when people are in a confined and not easily vacated space. From airplanes to cars to trains, flame retardants can play a key role in protecting travelers from the devastation of fire. Upholstered furniture and mattresses can be a major contributor to fires. They are often some of the first products to ignite i…

FLAME RETARDANTS HELP KEEP HOMES SAFE The average home now contains more than 20 electronic products, including televisions, smartphones, computers, gaming systems, and tablets1 . Electronics also include refrigerators, dishwashers, and other appliances. Today’s electronics contain more electrical components than in past years. Electronics, however, as energized devices, present fire threats, which is why manufactu…

Cost of Fire According to the National Fire Protection Association, in 2014 the total cost of fire was $328.5 billion, which was 1.9% of U.S. Gross Domestic Product (GDP). Over the years 1980 to 2014, the total cost of fire increased by 50.3%.1Of course, preventing injury or loss of life is the most important component of fire safety, but we also need to recognize that the costs of fires go …
