Polypropylene, also known as Pp Resin, is a thermoplastic polymer used in a wide variety of applications. Virgin Pp Resin is produced via chain-growth polymerization from the monomer propylene.As one of Rubber And Plastic,like Eva Resin,Pvc Resin,Pp Resin Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Plastic Pp Granules Resin properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.
Pp Resin is in many aspects similar to polyethylene, especially in solution behaviour and electrical properties. The methyl group improves mechanical properties and thermal resistance, although the chemical resistance decreases. The properties of Pp Resin Polypropylene depend on the molecular weight and molecular weight distribution, crystallinity, type and proportion of comonomer (if used) and the isotacticity. In Pp Powder Resin, for example, the methyl groups are oriented on one side of the carbon backbone. This arrangement creates a greater degree of crystallinity and results in a stiffer material that is more resistant to creep than both atactic polypropylene and polyethylene.

“The US wind power industry is heating up, and these figures in the first quarter show that the industry is recovering. Accurate technology, affordable prices, and continued demand for clean energy and domestic energy are some of the reasons for the strong growth in the wind energy industry. The chief executive of the American Wind Energy Association said. "With natural gas prices hitting $4 per gallon and still rising, the United States must implement long-term energy policies focused on domestic energy."
The 1100 MW wind capacity installed in the first quarter of 2011 was in 12 different states, some of which had double-digit growth. The states with the largest installed capacity in the United States in the first quarter were 293MW in Minnesota, 240MW in Illinois, 151MW in Washington, 119MW in Iowa, and 119MW in Nebraska.
Of the 5,600 MW currently under construction, one-third of them are in Oregon, Washington, and California, which has made the West Coast a leader in wind power project activity. "The states are still taking the lead in clear, fixed policies." Elizabeth, chief economist at the American Wind Energy Association. Salerno indicated that. She also pointed out that “10 years ago, California accounted for about 60% of wind power installed in the United States. At present, the state has the most powerful renewable energy target—renewable energy reaches 33% by 2020. California vowed to take the lead. Therefore, the wind energy capacity under construction in the first quarter reached 600MW."
First quarter of 2011 increased installed capacity of wind power in the United States
According to a report released by the American Wind Energy Association recently, in the first quarter of 2011, the newly installed capacity of wind power in the United States was 1,100 MW, and another 5,600 MW under construction was required to enter the capacity in the second quarter. The number of projects under construction is equivalent to twice the number of projects under construction in 2009 and 2010, and two-thirds of these capacities have already signed long-term purchase agreements with power companies, showing that this is a strong growth under a series of economic and political conditions. Sustainable industry. Currently, the total installed capacity of wind power in the United States is 4,1400 MW, generating enough clean energy to supply 1,000 homes in the United States.
