what is the function of flame,retardant and stabilizer in plastic resin?
Answers
Answer:
The term flame retardants subsumes a diverse group of chemicals which are added to manufactured materials, such as plastics and textiles, and surface finishes and coatings. Flame retardants are activated by the presence of an ignition source and are intended to prevent or slow the further development of ignition by a variety of different physical and chemical methods. They may be added as a copolymer during the polymerisation process, or later added to the polymer at a moulding or extrusion process or (particularly for textiles) applied as a topical finish.
Answer:
Flame retardants (FR) are chemical compounds added with an objective to inhibit/burning of the plastic.To prevent combustion, it becomes necessary to design a thermally stable polymer that has a lesser probability of decomposing into combustible gases under heat stress.
They are added to plastics to afford protection against heat (thermal), UV and mechanical degradation of the polymer during both processing and use. They can function as antioxidants, heat (thermal) and photo/light (UV) stabilizers, flame/fire retardants and oxygen scavengers.
