Phosphorous based FRs (PFRs) Phosphorus flame retardants (PFRs) (organic and inorganic) are more environmentally friendly, good thermally stable and have superior performance, resulting from the synergistic effect of P-N. They do not tend to form toxic gases since phosphorus is mostly locked into the char. Phosphorous FRs may be reactive (chemically bound) and additive (physical mixing) [2]. Lanxess [3] has…

Halogen-based flame retardants (Br-FRs) The Stockholm Convention (2001) listed 23 organo-halogen chemicals (including all BFRs) to be banned globally. The challenges of finding substitutes for banned halogen-containing flame- retardants include:A. Lower flame retardancy: Only 10 wt% of BFRs is equivalent to about 30-50% by wt of inorganic FRsB. High cost: Inorganic FRs is low-cost but require high loading. New HFFRs, …

Applications of Metallic Stearates-1 Properties of metallic stearates due to the unique structure of having polar and non-polar nature in the same molecule can be used in various functions in a variety of applications. They work as reactive processing aids, inert process enablers, mold release agents, acid scavenging agents, dispersing agents, and hydrophobizing agents. Here are a few applications where metallic st…

WHAT DO FLAME RETARDANTS DO? Flame retardants are a tool that can have a favorable effect on every key fire property, including ignitability, flame spread, heat release, and ease of extinction; albeit they do not necessarily have all of these effects simultaneously in every case. Some examples follow associated with well-known products in actual use where the effectiveness of the appropriate flame retardant…

Flame Retardants: Background and Effectiveness Fire safety can be achieved by means of active or passive fire protection. Passive fire protection involves using materials or products with superior fire performance so as to either minimize the probability of ignition or, if ignition does occur, minimize the damaging effects of the resulting fire. Flame retardants offer one way of providing passive fire protection.When a combu…

What is the difference between fire retardant paint and fire retardant coating Fire retardant paint is a kind of flame retardant coating made of film-forming agent, flame retardant, foaming agent and other materials. Fire-retardant coatings, which can be called flame-retardant materials, are composed of coating components such as binders (ie, film-forming substances), pigments, common coating additives, fire-retardant additives, and dispersion media. Excep…
