Plastics remained a bright spot for U.S. trade in 2008
By Tony Deligio
Published: October 21st, 2009
Despite a decline of 23% in the final quarter of the year, U.S. plastic exports increased by 6.7% in 2008 and eclipsed $50 billion for the first time ever, according to the latest international trade statistics for the plastics industry, which are summarized in a new report from the Society of the Plastics Industry (SPI; Washington, DC).
Exports during the fourth quarter of 2008 were off 23% from the prior quarter and 12% from the same quarter in 2007, but for the year, they exceeded $51 billion and accounted for approximately 4.4% of all U.S. exports. An overall trade surplus in plastics was not only maintained but expanded, as imports increased, but by only 3.0%, to just under $39 billion. The overall plastics trade surplus grew by nearly 20% from $10.9 billion in 2007 to $13.0 billion in 2008. Much of that surplus resulted from $18.4 billion in resins and raw material exports.

Carbon Nanotubes are being introduced for their enhanced performance. These include thermal and electrical conductivity, structural strength and stiffness, and thermal stability. A recently performed test showed that the Tek-MixTM process can disperse and percolate carbon nanotubes such that a 3½ % carbon nanotube loading can be used in pure HDPE, versus typical levels of 7% (shown by the arrow in the graph). It is difficult to disperse CNT's in HDPE; thus, high loadings are normally required to compensate for incomplete dispersion. As reported in Bayer literature, typical CNT dispersions have a large agglomerate size, such as shown below for Baytubes C 150P. The objective is to turn 750 µm particles, as received, into a network of fine nano fibers of diameter 1 to 2 nm.

U.S. Demand for Biodegradable Plastic To Reach 720 Million lbs in 2012
August 29, 2008 - The Society of Plastics Engineers (SPE) - Tech Focus Website (contact direct) -- Demand for biodegradable plastic in the U.S. is projected to rise more than 15%/yr to 720 million lbs in 2012, valued at $845 million. Although representing less than 0.5% of all thermoplastic-resin demand in 2007, biodegradable plastic will have substantial growth opportunities. Escalating crude-oil prices have made biodegradable plastics, which are sourced from renewable resources, more cost-competitive with petroleum-based conventional resin. However, continued price declines are necessary for demand for biodegradables to grow, and among the threats to further declines in prices are rapidly rising prices for corn. These and other trends are presented in Biodegradable Plastic, a new study from The Freedonia Group, Inc.
|
"US demand for biodegradable plastic will grow 15.5 percent annually through 2012. Gains will be driven by escalating costs for petroleum-based resins and growing initiatives that favor renewable resources. Polyester-based and polylactic acid resins will grow the fastest, while starch-based types remain the largest segment." - The Freedonia Group website
