Why use flame retardants Flame retardants are chemicals added to materials to interfere with combustion. This disturbance is usually to achieve some desired refractory properties - slow ignition, reduce flame spread, etc. Widely used in plastic, wood and textile fire protection.Phosphorus flame retardants (including organic phosphorus and inorganic phosphorus) can carbonize the combustion material to a…

Advantages and disadvantages of commonly used flame retardants In recent years, with the increase in the output of plastic products and the improvement of safety standards, flame retardant materials are more widely used. Generally speaking, flame retardant materials can be divided into organic flame retardant materials and inorganic flame retardant materials.The organic flame retardant has good flame retardant effect and the addition amount…

Weak Demand and Surging Supplies Cast Bearish Shadow on India's CPVC Market The bearish market sentiments have taken hold of India's Chlorinated Polyvinyl Chloride (CPVC) prices as demand remains weak ahead of the abundant supply along with a consistent movement of overseas cargoes. Despite starting the year with price increases, the markets softened in March and have declined since then due to strong import arrivals, particularly from China, which have…

What are flame retardants? As the name suggests, flame retardants are additives used to prevent materials from being ignited and inhibit the spread of fire. They are mainly designed for the flame retardant of polymer materials. Generally speaking, flame retardants mainly play the role of endothermic, covering, chain inhibition and non-combustible gas suffocation to achieve the flame retardant effect. Mate…

Flameout method of flame retardants 1. It produces a gas that smothers the flame. For example, antimony trioxide reacts with HCl from combustion in PVC to form a smoldering gas, namely antimony nitrogen oxide. 2. It can absorb the heat produced during combustion and cool down the combustion rate. For example, aluminum hydroxide contains up to 34% of chemically associating water in its molecules, which remains stab…

Flame retardant Flame retardant is a kind of additive which can prevent the ignition of polymer materials or inhibit the flame propagation. Common and important flame retardants are compounds of phosphorus, bromine, chlorine, antimony and aluminum. Flame retardants can be divided into additive type and reactive type. The additive flame retardants mainly include phosphate ester, halogenated hydr…
