Abstract
US demand to grow nearly 6% annually through 2010
Natural polymer demand is forecast to rise nearly six percent annually to $3.7
billion in 2010, reaching 1.7 billion pounds. The best growth is expected for
starch and fermentation products in light of increased capacity, lower prices
and environmental benefits. Polylactic acid demand will be bolstered by a more
competitive pricing structure with petrochemical- based polymers, particularly
in packaging and textile markets. Cellulose ethers will remain dominant with
demand expanding at a below average pace due to saturated applications and an
intensely competitive environment. Methyl cellulose is the leading cellulose
ether, with strong gains anticipated in the food and pharmaceutical markets.
Protein-based polymer demand will be driven by robust growth in biomedical use
for collagen and related products, yet constrained by subdued pricing for
wheat gluten. Demand for marine polymers such as alginates and carrageenan
will be fueled by continuing trends toward natural ingredients in foods,
nutraceuticals and cosmetics. Guar gum will present the best opportunities of
all exudate and vegetable gums, with food remaining the largest market. Gains
will be stimulated by rising demand in oilfield applications due to an upturn
in oil exploration, yet restrained by keen competition from xanthan gum and
cellulose ethers.
