Flame retardants for polyesters
Polyester Polyethylene terephthalate (PET) belongs to macromolecular compound. Is composed of terephthalic acid (PTA) and ethylene glycol (EG) by polycondensation to produce polyethylene terephthalate (PET), part of the PET by the under water pelletizing and finally generated.
Fiber grade polyester chip used in the manufacture of polyester staple fiber and polyester filament, polyester fiber is the supply of processing enterprises and related products, raw materials, polyester fiber as in the largest production varieties, chemical industry occupy nearly 80% of the market, so the market changes and development trend of polyester series of chemical fiber industry is the focus of attention.
At the same time there are bottles, polyester film and other purposes, is widely used in the packaging industry, electronics, medical, construction, automotive and other fields, which is non fiber polyester packaging application market is also the largest and the fastest growing areas of PET. It can be said that polyester chips are an important intermediate product connecting petrochemical products and many industries.
Before the use of flame retardant polyester is mainly by ten bromo two benzene ethane, decabromodiphenyl oxide represented halogen products.
In recent years, the flame retardant arise in the field of toxicology and environmental problems of bromine containing flame retardant of the dispute, the EU has introduced "electronic motor supplies directive in 2003" harm (RoHS ban), decided to use the July 1, 2006 ban PBB and PBDE brominated flame retardants.
The reason is that halogen flame retardant can not be recycled, burning and heating process will release harmful substances, threatening human health, environment and the next generation. Other countries have followed suit, so that manufacturers of flame retardant materials in various countries have begun to adopt a cautious attitude towards the use of brominated flame retardants in polymers.
In February 28, 2006, the "electronic information products pollution control management measures", which is called "China RoHS", was officially promulgated and implemented in March 1, 2007. The "management approach" explicitly listed in the electronic products "to limit the use of lead, mercury, cadmium, hexavalent chromium and six polybrominated biphenyls, polybrominated diphenyl ether two and other six kinds of toxic and harmful substances".
For environmental protection, polyester flame retardants urgently need to develop new products. At present there are three ways, one is the development of non halogen flame retardant, as phosphate esters, but this kind of polyester flame retardant for few varieties of products, high price, large impact on the performance of plastic processing is limited in the field of engineering plastics;the two is the development of inorganic flame retardants, such products are mainly Mg (OH 2) and Al (OH) 3, which is characterized by large amount, large impact on the performance of products, some high-end products do not apply, the dispersion problems are not well resolved; three is the halogen flame retardant developed other structure, has become a hot research and development, six twelve, four ring alkyl bromide tetrabromobisphenol A has been widely used in China, has reached 100 thousand tons of production capacity, these two kinds of defects in the products synthesized by flame retardant plastics is not resistant to migration, does not have to use, the environmental pollution is relatively heavy.
In foreign countries, tribromophenol (TBP) is mainly used as flame retardant materials.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)

Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent
Due to concerns about the risks of polybrominated diphenyl ether two to human and environment, the western developed countries in many years ago by some new brominated flame retardants polybrominated diphenyl ether instead of two. Brominated epoxy oligomer is one of the most alternative substitutes.
The specific approach is used to block the end epoxy tri brominated epoxy oligomer, metal adhesion so that the epoxy becomes weak, membranous changes, and bromine content increased by about 10%, so it can not only reduce the amount of fire retardant, but also can improve the impact resistance.
Based on these advantages, the rapid increase of international market demand tribromophenol. In the case of Japan, in early 1990s, demand tribromophenol increases exponentially, demand in 1994 more than 4000 tons, demand in 2000 more than 7000 tons, the domestic has been imported from the US and Western europe.
Products of good color, add less, and the resin has good biocompatibility, high flame retardant efficiency, good processing, product Recyclable and combustion does not produce dioxin / two benzofuran (PBDD/PBDF), in accordance with European Union regulations and dioxin TSCA 40766.25 EPA final regulations for environmentally friendly flame retardant. At present, the products mainly rely on imports in China, and a few domestic manufacturers are in the R & D period, most of which can not achieve industrial production.
Flame retardant industry developed rapidly in recent years, the project of synthetic products are mainly used in engineering plastics used in the fields of electronics, electrical appliances, electrical, communications, textile, automobile, machinery, sports and leisure products such as modified.
With the EU RoHS ban, as well as other countries (including Chinese) follow the example of project products as environmentally friendly flame retardant showed a huge market space, the amount of 30 thousand tons or more, if the implementation of China's "management measures" amount will reach hundreds of thousands of tons, the product has been widely used abroad and the amount is huge, if products are exported to foreign markets will produce greater economic benefits.
