Shandong Taixing New Materials Co., Ltd. specializes in the lookup and manufacturing of ammonium polyphosphate, and is a main world producer and supplier.
As an environment friendly and environmentally pleasant flame retardant, polyphosphate ammonium is broadly used in more than a few necessary industries such as textiles, plastics, and coatings. This phosphorus nitrogen synergistic flame retardant performs an essential function in cutting-edge enterprise due to its special chemical shape and flame retardant mechanism.
In the cloth industry, polyphosphate ammonium is the principal therapy agent for flame retardant textiles. It undergoes cross-linking response with cellulose fibers via immersion rolling drying process, forming a long lasting flame retardant effect. Research has proven that cotton fabric handled with polyphosphate ammonium can make bigger their closing oxygen index from 18% to over 28%, and can nonetheless preserve exquisite flame retardancy after 50 washes. This attribute makes it broadly used in the subject of flame-retardant textiles such as protecting garb and curtains.
In the plastic industry, polyphosphate ammonium is used as an additive flame retardant. Its thermal decomposition temperature is high (above 280 ℃), and the decomposition process produces non combustible gases and an expanded carbon layer, effectively isolating heat and oxygen. Experimental data shows that adding 20% polyphosphate ammonium to polypropylene material can achieve a vertical combustion level of V-0. Compared with traditional halogenated flame retardants, polyphosphate ammonium has the advantages of low smoke and low toxicity, and is particularly suitable for electronic and electrical casing materials.
In the field of coatings, polyphosphate ammonium is introduced into coating systems through chemical bonding or physical mixing. It can not only improve the flame retardant performance of the coating, but also enhance the leveling and adhesion of the coating. The application of wood fireproof coating shows that adding 15% polyphosphate ammonium can reduce the combustion rate of wood by more than 60%. This characteristic makes it have broad application prospects in the field of building fireproof coatings.
With the increasingly strict environmental regulations and advances in materials science, the application fields of polyphosphate ammonium are constantly expanding. The development of a new type of nanoscale polyphosphate ammonium not only maintains excellent flame retardant properties, but also improves the mechanical properties of the matrix material. In the future, polyphosphate ammonium will play an important role in more fields, promoting the development of flame retardant materials towards high efficiency, environmental protection, and multifunctionality.
