Non-Halogenated Flame Retardants Non-Halogenated Flame Retardants are chemicals that include nitrogen and phosphorus compounds. They form a protective burn in the condensed phase or release free radicals for displacing oxygen in the gas phase inhibiting the flame. Applications of this chemical include paints and coatings, adhesives, electronic equipment, and wires. Epoxy resins are used in these applications and are coupled with flame retardant additives to improve their fire resistance. The demand for non-halogenated flame retardants is expected to rise in near future owing to rapid industrialization in the BRICS countries. This material is also used in the production of electrical equipment and automobile parts. The main mechanism of flame retardancy is chemical. First, the material reacts with free radicals produced during combustion. This reaction results in a reduction in flame density and lowers the burning rate of combustible materials. Second, a non-halogenated flame retardan...

  Vacuum Packaging is a technique of sealing small items such as bottles, which removes air within the container before sealing. This technique involves putting items into a protective plastic sheet package, removing air within and sealing the pack. Small shrinkable plastic sheets are used to get a tight seal around the contents. Vacuum Packaging is often used for perishables such as perishable foods. In this case, the seal is done using low-pressure nitrogen, with a tiny valve at its tip. The package is then placed in an oxygen enriched chamber to promote rapid evaporation of the oxygen from the liquid. High-pressure air or steam is also used to achieve the same result. In order to remove any trace of oxygen, the packaging material is placed into an ultra violet light source for about one minute, thus removing all traces of oxygen. In August 2021, U.S.-based Globe Food Equipment Company launched a new line of vacuum packaging machines. One common application of vacuum packaging ...
