Polyvinyl chloride (PVC) plastic halogen free flame retardant
With the progress of plastics technology, various properties of materials have been greatly improved. Plastics are applied more and more in aerospace, transportation, architecture, electronic and electrical appliances, and Internet hardware. But most plastic materials are easy to burn and burn.
In order to solve the shortcomings in the application process of flammable plastic, flame retardant plastic attention all over the world, in addition in PVC (polyvinyl chloride (PVC) flame retardant plastic halogen-free flame retardant materials is a convenient method to achieve the safety standard of plastic materials more and more strict, so in recent years, the global polyvinyl chloride (PVC) plastic no amount of market and sales of halogen flame retardant has been on the rise.
Halogen - containing flame retardants have been widely used in plastics because of their good flame retardancy, high flame retardancy efficiency and cheap price. However, the addition of halogen containing flame retardants will not only cause negative effects on the environment, but also produce a lot of toxic and corrosive gases and fumes during the combustion process. The fire may cause suffocation and death, which will lead to the increase of fire hazard. Halogen-free flame retardants have many advantages, such as environmental protection, safety, smoke suppression, innocuity and low cost. Therefore, research and development of polyvinyl chloride (PVC) plastic halogen free flame retardants has become a hot research topic in plastic fire retardants at present.
The types of halogen free flame retardants for polyvinyl chloride (PVC) Plastics: the research of halogen free flame retardants is still in progress. With the development of research, the types of halogen free flame retardants will definitely increase. At present, the types of halogen-free flame retardants of PVC plastics include inorganic flame retardants, halogen-free intumescent flame retardants, organophosphorus flame retardants, organosilicon flame retardants, nitrogen flame retardants, and so on. The five types of halogen free flame retardants are mainly composed of inorganic halogen flame retardant, halogen-free intumescent flame retardant, organic phosphorus flame retardant, organic silicon flame retardant and nitrogen flame retardant.
Inorganic flame retardants have many advantages, such as good stability, low toxicity or innocuity, no volatilization during storage, no easy to separate from plastics, abundant raw materials and low cost. They have dual functions of flame retardant and filling, and are environmentally friendly. They are promising flame retardants. Inorganic flame retardants mainly include Sb2O3, Al (OH) 3, Mg (OH) 2, inorganic phosphorus system and so on.
Three oxidation of two antimony (Sb2O3) is the most widely used type of inorganic flame retardant. Because of its poor effect when used alone, it is often used with organic halides and plays a synergistic effect, called synergist. It has excellent flame retardancy and can be widely used in PVC and polyolefines and polyester and other plastics. But it has a stimulating effect on the nose, eye and throat, inhaling the body will stimulate the respiratory organs, contact with the skin can cause dermatitis, the use of attention should be paid attention to protection.
Aluminum hydroxide Al (OH) 3 is customarily called hydrated alumina. It is a fine white powder with crystal water 34.4% and 200 degrees centigrade, which can absorb a lot of heat. In addition, aluminum hydroxide is added to plastic, and the water vapor and white smoke released during combustion will dilute the black smoke produced by polymer and play a role of masking. Therefore, it has the function of reducing smoke and toxic gas.
Tris(2-chloroisopropyl)Phosphate(TCPP)
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Due to the transport process to avoid collision damage, Tris2-chloropropyl phosphate TCPP packaging methods generally used 250KG galvanized iron drum.
Below to introduce some of Tris2-chloropropyl phosphate TCPP packaging:
Net weight 250KG/ galvanized iron drum (a small cabinet pallet loaded 20 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Company 1.5 hour drive from Shanghai, the general sent to Shanghai port, the goods from customs inspection to the fastest one week after, the slowest ten days.
In view of the domestic and foreign demand is relatively small clients, also can use 50KG plastic bucket.
If you have special requirements on the Tris2-chloropropyl phosphate TCPP packaging, please contact us, try to meet the packaging requirements of customers.
Magnesium hydroxide Mg (OH) 2 is slightly worse than aluminum hydroxide, which can affect the mechanical strength by adding a large amount of plastic in the plastic. After the surface treatment of the coupling agent, the bonding force with the resin can be improved so that it has dual functions of flame retardancy and filling. It is commonly used in EP, PF, UP, ABS, PVC, PE and so on.
Inorganic flame retardant mainly refers to the red phosphorus. It is a flame retardant with excellent performance, high efficiency, low toxicity and smoke suppression effect of flame retardant, used as a flame retardant has been more than 20 years, is a highly valued flame retardant, can be used in a variety of plastic, but usually need to cooperate with other agents in order to play its role in flame retardant. Red phosphorus flame retardant is also insufficient, mainly include: red phosphorus in the use of flammable, explosive, poor stability and easy to be oxidized into acid; long-term contact with air will release toxic phosphine; red phosphorus itself is red, easy to make products coloring; red phosphorus also easy to absorb moisture, and polymer compatibility is poor, which limits its wide as the application of flame retardants.
Other inorganic flame retardants include flame retardants, synergistic agents, flame retardants and smoke suppressants, and some less flame retardants, such as molybdenum compounds, borates, layered silicate, tin compounds (zinc stannate and zinc stannate). Molybdenum compounds are the best smoke suppressants that have been found so far. Usually the use of molybdenum trioxide and ammonium molybdate. The United States has developed a series of molybdate smog - suppressants without ammonium, which can withstand the processing temperature above 200 degrees centigrade.
Halogen free intumescent flame retardant (IFR) is a halogen-free flame retardant with phosphorus and nitrogen as the main component. It has high flame retardancy, no melting drop, good resistance to long or repeated exposure to flame, no halogen, no antimony oxide, low smoke, no poison, no corrosive gas generation and so on.
IFR is mainly composed of three parts: the first part is the acid source, also known as the dehydrating agent or the carbonization accelerator. Usually for inorganic acid or inorganic acid compounds, such as phosphoric acid, sulfuric acid, boric acid, phosphoric acid, ammonium phosphate and ammonium polyphosphate (APP), and can promote the formation of resin, carbonized materials; the second part is the carbon source and carbon forming agent, mainly for some high carbon compounds or polyhydroxy carbohydrate, such as starch, pentaerythritol (PER) and its two dimer and trimer; the third part is also called air foam source, can release the inert gas, nitrogenous compounds, such as urea, melamine (MEL), dicyandiamide, APP etc.
