Polypropylene Halogen Free Flame Retardant

Since the rise of modern industry, polypropylene has been widely used in utensils because of its light weight and low price. However, the danger of fire is not uncommon, so flame retardant technology has gradually been respected. The flame retardants used at the beginning relied on halogen substances, although the effect was outstanding, but the incineration lost toxicity and the environment was harmed, so the intention of improvement came into being. By the end of the 20th century, scientists had carefully studied the method and mixed halogen-free flame retardants into polypropylene to make it self-extinguish in the fire and do not produce highly toxic fumes. From the initial expansion type to the later generation of phosphorus, nitrogen and nano-composites, the production method has become increasingly sophisticated. Today, halogen-free flame retardant polypropylene has been widely distributed in cables and household appliances, taking into account safety and environmental protection, and is really a corner of the progress of material science and technology.

Polypropylene halogen-free flame retardant is refined by modern technology. Its properties are clean, halogen-free, and meet the needs of environmental protection. Adding polypropylene can instantly give the material excellent flame retardant properties. When burning, no halogen gas is released, reducing the harm to the human body and the environment. Its particle size is uniform, good dispersion, does not affect the mechanical strength and appearance of the product, especially suitable for wire and cable, household appliances and other fields. Different from traditional halogen-containing flame retardants, it does not produce thick smoke and toxic gases in case of fire, reflecting the concept of green and low-carbon.

The halogen-free flame retardant of polypropylene is made, and high-purity polypropylene is selected as the base, supplemented by phosphine-based, nitrogen-based and inorganic hydroxide-based flame retardant materials. First, each raw material is finely ground and mixed, with an appropriate amount of dispersant, and slowly put into the high-temperature melt extruder to make it evenly mixed. In the meantime, catalysts such as peroxides can promote cross-linking or grafting reactions between flame retardant groups and polypropylene chains, change the macro-structure, increase its thermal stability and smoke suppression performance. The whole process should be controlled at temperature and speed to prevent the pyrolysis of raw materials from failing. After discharging, cool and granulate to obtain halogen-free flame retardant materials. Its flame retardant effect, synergistic phosphine and nitrogen release of non-flammable gas, phosphine-based carbon layer formation, hydroxy endothermic decomposition of water, dilution of the gaseous phase, and isolation of oxygen connection, three effects and use, to form a flame retardant function, green safety, suitable for harsh work.

Polypropylene is inherently malleable, but it is flammable in case of fire. Today's halogen-free flame retardants hide subtle chemical reactions. The method is to introduce nitrogen, phosphorus and other elements into polypropylene to synergistically generate an efficient flame retardant system. During incineration, the flame retardant is thermally released phosphoric acid, which prompts the carbon layer to adhere to the surface to isolate oxygen and heat sources; the nitrogen source is thermally decomposed to precipitate inert gases, diluting the flammable materials in the combustion area. If modified, the compatibility between the flame retardant and the polypropylene can be improved through blending, grafting, surface coating, etc., and its distribution is enhanced. Finally, the material has both flame retardant properties and bulk mechanics, and is environmentally friendly and halogen-free. The combination of chemical reaction and modification makes polypropylene a great benefit between safety and practicality.

Polypropylene halogen-free flame retardants are sometimes called polypropylene halogen-free flame retardant inhibitors in the industry, also known as PP halogen-free flame retardant masterbatch, or labeled as environmentally friendly polypropylene flame retardant. There are several ends of synonyms, such as polypropylene halogen-free flame retardant additives, PP halogen-free fire retardant, polypropylene halogen-free fire retardant masterbatch, which can be used universally and are widely used. To the trade name, merchants often have their own names, such as "Poly-An halogen-free flame retardant SC-800", "Green Flame PP Halogen-free 10A", "Jingyan PP-MFR1", or "Chang Flame Halogen-free PP Flame Retardant Granules". However, its basic properties are based on polypropylene, which is bromine-free and halogen-free Although these names are different, they actually refer to a thing, which may have some emphasis, and the class is distinguished by characteristics such as environmental protection, heat resistance, and easy processing.

Polypropylene Halogen Free Flame Retardant is a new material used in this world's craftsmanship. It has flame retardant properties and is halogen-free. It is an environmentally friendly choice. It is flexible and self-extinguishing in case of fire without releasing harmful gases. However, when operating, it is especially expensive to be safe and must be done according to the specifications. Anyone who stores this thing must be in a dry and ventilated room, away from fire sources and high temperatures, and do not mix with oils and oxides to prevent chemical reactions or fires. Before using it, be sure to wear protective gear, such as gloves, goggles and masks, to prevent fine dust from flying, accidentally entering the mouth and nose, and damaging breathing.

Polypropylene halogen-free flame retardants are modern products, used to replace halogen-containing flame retardants, and are widely used in equipment manufacturing and electronic devices. However, the study of its toxicity is particularly urgent. The main components of this flame retardant are mostly phosphorus, nitrogen and other compounds, and do not release halogen gas when incinerated, so few harmful gases such as dioxin escape. However, although it reduces the harm of the environment, it may also have trace amounts of organophosphorus substances during the pyrolysis process, which has a chronic potential impact on the organism. The experiment took mice as an example. After ingesting large doses, there was no significant abnormality in liver and kidney function, but long-term micro-exposure still needs to be further investigated. If used in a standardized manner, it is not harmful to the human body, and it is also more friendly to air and water. Overall, polypropylene halogen-free flame retardants are safer than traditional flame retardants, but their long-term toxicity cannot be ignored. Therefore, their effects in different proportions and environments should be carefully evaluated.
