Dalian plastics (LLDPE) futures index climbed strongly higher on the 10th. The main 1105 contract closed at 12,370 yuan/ton, up 360 yuan/ton. Yesterday, even plastic opened slightly lower, then the long capital in the market actively involved, making the futures price pulled up sharply to 12,200 near. Fundamentally, Asian ethylene monomer prices rose to stimulate LLDPE production costs rose again, prompting futures prices to maintain oscillation near 12,200. And now is about to enter the peak season of agricultural film demand, producers need to stockpile also to a certain extent on the LLDP support, is expected to the market even plastic is expected to shock higher. New York Mercantile Exchange (NYMEX) crude oil futures closed close to flat on the 10th, traders in Egypt President Mubarak (Hosni Mubarak) will step down under the expectation of suspend trading. The March crude futures contract settled up $0.02 to $86.73 a barrel, after rising to a high of $87.90 a barrel earlier in the day. the ICE Brent crude futures contract fell $1.26 to $100.56 a barrel. Egyptian military and ruling party officials said Mubarak will soon address the nation and meet the demands of demonstrators. Demonstrators insisted that Mubarak step down immediately […]

Technical Standards and Specifications for Flame Retardant ABS Plastics
ABS is a flammable material and is classified as HB according to UL94. ABS burns quickly when it catches fire and emits a lot of toxic gas and black smoke, which is not conducive to practical applications. With the progress of science and technology and the improvement of quality of life, people have become more and more safety conscious, and strict fire-retardant requirements have been put forward for plastic materials used in automobiles, buildings, household appliances, office supplies, etc. at home and abroad, and corresponding technical standards and specifications have been formulated. Flame retardants are added to ABS by common methods, including inorganic flame retardants and organic flame retardants (e.g., halogen compounds, phosphorus-based flame retardants). Flame-retardant types have efficient flame retardancy but may have other properties that are not good (e.g., aging, high cost). Chemically modified ABS requires a specific production process and a more complex process. Currently, flame retardant modification of ABS materials is based on the addition of highly efficient halogen-containing flame retardants. Heat-resistant ABS resins generally have a heat deflection temperature of 90 to 105°C and have good heat resistance, toughness, and fluidity. ABS heat resistance can be improved by reducing rubber content and increasing SAN molecular […]
