Polypropylene is a common plastic material with good heat resistance, corrosion resistance and mechanical properties, so it is widely used in industry and daily life. However, due to its flammable properties, flame retardants need to be added to improve its flame retardant properties. The following will introduce some common flame retardants that can be applied to polypropylene.
Aluminum triphosphate: Aluminum triphosphate is a commonly used halogen-free flame retardant that can effectively improve the flame retardant properties of polypropylene. It can release phosphorus oxides at high temperatures to form a protective layer to prevent the spread of oxygen and heat, thereby achieving a flame retardant effect.
Aluminum hydroxide: Aluminum hydroxide is a non-toxic, odorless, and non-corrosive flame retardant that can effectively improve the flame retardant properties of polypropylene. It decomposes at high temperatures to release water vapor, absorb heat, and reduce the burning rate and heat release of polypropylene.
Aluminum silicate: Aluminum silicate is a halogen-free flame retardant that can effectively improve the flame retardant properties of polypropylene. It can decompose at high temperatures to release water vapor and silicon dioxide to form a protective layer to prevent the spread of oxygen and heat, thereby achieving a flame retardant effect.
Ammonium polyphosphate is a phosphorus-nitrogen flame retardant with good flame retardant properties and thermal stability, and is widely used in polypropylene materials. Ammonium polyphosphate can decompose at high temperatures to release phosphorus oxides and ammonia, forming a carbon layer to prevent the spread of oxygen and heat, thereby effectively improving the flame retardant properties of polypropylene. In addition, ammonium polyphosphate also has the characteristics of low toxicity, low corrosiveness and environmental friendliness, making it an ideal polypropylene flame retardant.
In the industrial field, ammonium polyphosphate is widely used in flame retardant materials for polypropylene, such as electrical equipment, building materials, automotive parts and other fields. Its excellent flame retardant properties and environmental protection characteristics have been widely recognized and applied. At the same time, as people’s requirements for environmental protection and safety performance increase, ammonium polyphosphate, as a halogen-free flame retardant, will play an increasingly important role in polypropylene materials.
In general, polypropylene, as a common plastic material, needs to add flame retardants to improve its flame retardant properties. Aluminum triphosphate, aluminum hydroxide, aluminum silicate, etc. are common flame retardants that can be applied to polypropylene, and ammonium polyphosphate, as a phosphorus-nitrogen flame retardant, has broad application prospects in polypropylene.
