Antimony trioxide and Mg Compounding:PVC COMPOSITES FLAME RETARDANT SK-500

K500 falls into compound flame retardant additives with low-smoke, fireproof and activated characteristics. It is a multiple retardant system with main ingredients of antimony-magnesium. These two elements are mutually cooperative and enhancing each other. It is generally applied to electric wire and cable PVC and soft PVC. It characterizes good flame retardation and smokeproof operations. It is an excellent compound flame retardant and smokeproof additives which optimizes the flame retardation and physical nature. Compound flame retardant comes with outstanding cooperativeness. No change to physical nature of the PVC materials is found when it is applied to PVC in large quantity. The ideal results can be achieved by adding 3-6 doses into the formula. When applied 5 doses to PVC, the oxygen index is as high as 33%. It is the best, safest, high-effective environmental flame retardant additives to be applied to PVC.

Songwon develops flame retardants

Korean company Songwon has introduced a number of new halogen-free flame retardants. Songflame YA 010 and YA 020 are based on phosphine oxides. The company says that they are designed to be reactive with the resin backbone, principally epoxies, to give long term stability with the key advantages of being environmentally safe, non toxic and non corrosive. End-use application for glass reinforced printed circuit boards.

Songflame TP100 is a halogen-free flame retardant based on phenol/bi-phenol polyphosphate and is suited to a wide range of thermoplastic resins, particularly polycarbonate, polycarbonate blends with ABS and a wide range of polyesters. This new molecular structure, having a higher glass transition temperature, has the key advantage of boosting the thermal strength properties in the resin matrix.

Halogen-free flame retardants market worldwide

Halogen-free Flame retardants market will increase from 1.62 bn US $ in 2005 and to 2.72 bn US $ in 2010 worldwide. Nanotechnology will play the key role in improving fire-retardant performance and reducing production costs.Halogen-free flame retardants show strong increase worldwide. 

In Western Europe, USA and Japan, the public consciousness of the hazardous halgonenated products, the industrial end-user initiatives and the environmental legislation push together the market trend to halogen-free products. In China, Eastern Europe and other parts of Asia, the booming economy and the strengthened fire protection standards stimulate the market of fire retardants overall, from which the halogenated and non-halogenated products both benefit.

The highest increase is to be seen in China with more than 13 percent. Slightly slow growth in Western Europe and USA, ranging from 9%-11%, The world market in total will grow from 1.62 bn US $ in 2005 and to 2.72 bn US $ in 2010. The average global annual growth rate is more than 10%, in comparison with 5% of the general flame retardants market.

Plastic applications count for more than 50 percent of the quantity produced but fire protection applications like building materials and insulation, cables and wood products count for more than 60 percent of the profit potentials. Nanotechnology improve coatings, enables synergism with other materials and converge with processes and chemical technologies already today. 

The result is a better retarding of flame spread and smoke development. New chemicals are developed to improve the flame retardancy and one of the most promising technologies and substances are nanocomposites ( polymer - clay nanocomposites ) which can substantially improve perfomance. Other important technology trends include intumescent systems, inherently flame retardant polymers and so on.

The future of the halogen-free flame retardants will largely depend on the technological development, the drive from industrial end-users and the environmental legislation.

China's has only discovered 35% of mineral resources to date

China's current proven mineral reserves are estimated at only about 35% of the country's total, according to the latest prospecting results from the China Geology Survey Bureau (GGS) released at the Ministry of Land and Resources-organized China Mining 2007 conference, held in Beijing yesterday.

The CGS, under the supervision of the Ministry of Land and Resources (MLR), announced at the conference that China's current proven reserves of iron, copper, aluminum, lead, zinc, manganese, niobium, tungsten, tin and gold are estimated to account for between 26% to 59% of the country's total reserves.

The bureau has made numerous discoveries along the Eastern Tethys Copper Belt in the Tibet Autonomous Region, which are estimated to contain in excess of 50 million tonnes of probable copper resource reserves.

A large number of lead and zinc deposits have been discovered in the Yangtze Craton, which covers Shaanxi, Hubei and Hunan provinces, as well as the Guangxi Zhuang Autonomous Region, estimated to contain possible lead and zinc reserves totaling 20 million tonnes.

Finally, only about 49% of China's iron ore reserves have been discovered to date, leaving an estimated 70 billion tonnes of undiscovered reserves. – Interfax

Magnesium prices are expected to jump in 2008

Supply shortages, import tariffs seen increasing prices

Magnesium buyers estimate they may pay an average $2.50/lb on the spot market in 2008, compared with $1.60 so far this year. Reason: Limited supply from major global suppliers, which is expected to boost market prices for the metal used in light metal die castings and, as an alloy with aluminum, in beer and beverage cans.

Market reports say U.S. Magnesium of Salt Lake City and Dead Sea Magnesium of Beer Sheva, Israel, have stopped booking guaranteed-price supply contracts for next year's deliveries. Reason: U.S. Magnesium has committed 9,900 tons of magnesium to General Motors while Dead Sea Magnesium has committed large tonnage to Volkswagen. Upshot: Spot market sales for January deliveries are being handled by traders (mostly with material from China and Russia that are subject to dumping duties) at $2.10, as compared with November deliveries averaging $1.90lb.

China likely to keep retrenching foreign investment in resources

China is likely to keep retrenching foreign investment in the resource field, said a research report from research institute Anbound Consulting.

Anbound noted the National Development and Reform Commission (NDRC) stated on November 7 the government will no longer encourage foreign investment in the development of several types of ores so as to protect rare or unrenewable mineral resources.

The Catalogue of Industries for Foreign Investment (revised in 2007) jointly issued by NDRC and the Ministry of Commerce on October 31 will take effect as of December 1, 2007. In the new Catalogue, NDRC said China will not encourage foreign investment in rare or unrenewable mineral resources. Foreign investment is no longer allowed to explore and mine some important unrenewable mineral resources, and is restricted or forbidden to access projects of high energy consumption and pollution.

The development of copper, zinc, lead and bauxite is removed from the category of industries where foreign investment used to be encouraged; exploring and mining of tungsten, tin, antimony and molybdenum are listed in the category of forbidden industries, rather than restricting foreign investment, and gold, silver and platinum remain in the restrictive category.

The revision of the Catalogue of Industries for Foreign Investment is part of the central government's macro control in the form of industry policy, said Anbound.

The stipulation on not encouraging foreign investment in China's key mineral resources, as the government's fresh measure on saving energy and cutting resource consumption, displays the government's attempt to strengthen control over mineral resources on one hand, and reflect the change in the use of foreign investment on the other.

It is foreseeable that retrenching in the mineral resource field has just started, said Anbound, adding that the limit on foreign investment in the resource and energy field may expand in the future as China remains short of resources and energy. – Asia Pulse
