    HIPS Flame Retardant HIPS Flame Retardant
    General Information
    Historical Development
    Since modern technology has changed with each passing day, the use of process plastics has become more and more extensive. HIPS, known as high-impact polystyrene, first emerged in the 1950s. It is synthesized from styrene and butadiene, which is both tough and light. However, the plastic material is flammable, and the fire is rampant, which has triggered scholars to explore the way of flame retardancy. At first, halogen-based flame retardants were applied to HIPS, although the effect was short-lived, and the discussion of tobacco toxicity followed. In the 1980s, environmental awareness gradually became apparent, and European and American countries took the lead in advocating halogen-free flame retardancy, replaced by new phosphorus and nitrogen-based agents, which all benefit from suppressing smoke and reducing harm. Continued, the use of nano-fillers and synergistic agents has made the flame retardant effect more and more obvious. Nowadays, HIPS flame retardant products are widely used in electronics, home appliances, construction and other fields. They not only adhere to traditional functions, but also meet the needs of safety in the times. They are a witness to the progress of materials.

    Preparation Method
    Polystyrene and polybutadiene are selected as the base, with brominated or phosphorus-based flame retardants, and supplemented by synergistic agents. First, a polymer solvent is mixed, stirred evenly, and heated until dissolved. Then a free radical polymerization reaction is initiated at high temperature, so that the flame retardant is uniformly blended with the matrix. In the reaction, the catalyst uses peroxide to initiate chain polymerization, which promotes the synergistic embedding of styrene monomers and brominated or phosphorus-based flame retardants into the system to form a stable copolymerization structure. During heat treatment, the temperature is controlled at 200 to 250 degrees Celsius, and it lasts for several hours to promote the growth of polymer chains and improve flame retardant efficiency. After the reaction, the HIPS flame retardant material is precipitated by rapid cooling, washed with water to remove impurities, and The preparation process is simple, the catalytic mechanism is clear, and the resulting products have excellent flame resistance, which is widely used in many fields such as electrical shells and building materials.
    Chemical Reactions & Modifications
    High impact polystyrene (HIPS) is the copolymerization of styrene and a small amount of butadiene. It is flammable by nature. If it is not modified, it is difficult to meet the demanding safety needs. To enhance its flame retardant properties, flame retardants must be added by means of chemical reactions. Commonly used are halogens, phosphorus series, etc. Halogen flame retardants are combined with polymer molecular chains, and through mixing and melting processes, the flame retardant components are evenly distributed in the matrix. When exposed to high flame temperature, halogens release hydrogen halides, block the transfer of free radicals, and inhibit combustion chain reactions. Phosphorus-based flame retardants generate polyphosphoric acids during pyrolysis, which contribute to the carbon layer covering the polymer surface and isolating oxygen. When compounding and modifying, synergistic agents such as antimony trioxide or nanomaterials are also used to enhance the flame retardant effect. After such modification, HIPS performance is safer and is widely used in the fields of electronics and electrical appliances.
    Synonyms & Product Names
    HIPS flame retardant, with many pseudonyms, or high impact polystyrene flame retardant material, or flame retardant HIPS plastic, also has high impact flame retardant PS, flame retardant grade high impact PS phase number. The market circulation of commodity names is more complex, such as FR-HIPS, HIPS FR, flame retardant high impact PS, flame retardant polystyrene, fire-resistant HIPS and fire-resistant HIPS, etc. All these names, although different, refer to the same thing, its quality is tough, and it has the characteristics of heat resistance and flame resistance. The industry or simply referred to as FR-HIPS, or attracted by the name of high flame retardant impact PS, are used in the field of flame retardant requirements such as electrical and electronic, home appliance shells, instrument accessories, etc. The similarity and difference are usually referred to as one.
    Safety & Operational Standards
    HIPS flame retardant materials are the essence of synthetic resins. They are tough and flame retardant, and are suitable for many processes. Although their performance is superior, they are not suitable for operation, and there are also hidden dangers. Where this material is used, safety and operation regulations must be clear. The appliance is placed in a ventilated place to prevent the accumulation of toxic gases; the operator should wear gloves and masks to prevent particles and harmful gases from entering the body. During construction, do not approach the fire, stay away from the open flame, considering that although it is flame retardant rather than non-flammable. The method of storage is to keep away from the heat source and avoid direct sunlight to prevent the variation of the character. If there is any leakage or debris dispersion, it must be removed with special equipment before it can continue. HIPS flame retardant materials should not be mixed with strong oxidants, acids and bases, for fear of adverse reactions. After the operation, clean the utensils and hands in time to avoid residue. If there is any suspicion of inhaling harmful gases, it is advisable to stay away from the construction site, breathe fresh gas, and seek medical treatment if necessary. In the workplace, emergency facilities such as fire extinguishers and protective clothing should be prepared. In case of fire, they can be dealt with quickly. Beginners in operation must be instructed by experienced workers, and do not rely on self-knowledge. Where purchasing, product certificates must be reviewed to verify compliance. Do not be greedy for low prices and cause losses. Every time the rules and regulations are made, they should be publicized to the public, and the order of punishment and reward should be made clear, so that everyone knows what to follow. In short, those who hold this material should be wary and take the road of safety, and the disaster will be far-reaching, efficient and profitable, and there will be no blame to worry about.

However, its chemical properties are complex, and although the appearance is safe, it actually contains impurities such as bromine, phosphorus and chlorine. Contact with the emitted gas, or at high temperature or during incineration, harmful particles escape, which can easily cause respiratory distress, throat burning, dizziness, nausea, allergies and other diseases. Long-term exposure, or damage to liver and kidney, especially pregnant women and young children. Animal experiments are mainly rodents, and it is seen that their blood and liver are poisoned. For this reason, it should be properly discarded to prevent secondary pollution. Although the chemical properties can be flammable, the toxicity cannot be ignored. It is necessary to choose the process well, and use both ventilation and protection to ensure that the security is safe.
