Nano Granule

Polymers are commonly reinforced using fillers of various sizes in order to reduce their limitations and weaknesses and thereby expand their range of applications. The use of nano scale fillers to improve the mechanical and physical properties of polymers has led to the development of a wide variety of polymeric nanocomposites.

Nano granule, a product manufactured by Hafez Varesh Knowledge Based Production Complex, is produced by combining polymeric materials such as polyethylene (PE) and polypropylene (PP) (or a blend of both) with powdered materials and specific nanoparticles.
These nanoparticles include boric acid, borax salts, ammonium pentaborate, monoammonium phosphate, ammonium phosphate, chlorinated paraffin, titanium dioxide nanoparticles, and barium oxide nanoparticles, which are processed and converted into nano granules.

The result of this process is a flame-retardant polymer that does not burn even under direct exposure to fire.

This polymer exhibits high moldability in injection molding and rolling processes and can be converted into fire-resistant plastic films and sheets.
The nanoparticles used in this product have particle sizes ranging from 10 to 300 nanometers. Nano granules can also be produced in various colors.

Features and Advantages of Flame Retardant Nano Polymer Composites

Flame-retardant nanopolymer composites are advanced and innovative materials that significantly enhance fire safety properties by incorporating nanomaterials into the polymer matrix.
These composites are not only lighter and stronger, but the use of nanoparticles such as nanoclays, carbon nanotubes, or graphene also improves thermal stability, mechanical strength, and fire resistance.

Nanomaterials can increase the thermal decomposition temperature of polymers and enhance their resistance to heat, thereby significantly reducing the likelihood of ignition.
In addition, nanoparticles reinforce the polymer matrix structure, resulting in stronger and tougher materials capable of withstanding higher levels of stress and impact.

Importance of Using Nano Granules

Nanomaterials act as a barrier that reduces the release of flammable gases and heat transfer, thereby delaying ignition and flame propagation.

The use of nanomaterials allows for a reduction in the consumption of flame retardant chemicals, which are often toxic, while still achieving effective flame retardancy.
