urethanes generally will lead the advances Growing competition from other expandec materials, such as thermoplastic olefins, wil challenge further growth of polyurethanes. however. Freedonia estimates that the polyurethane market in the USA amounted to more than 1.50 million tonnes in 1996.

MARKETING Foamed plastics: a $16 billion market in the USA Demand for foamed plastics in the USA is forecast to rise at 3% a year, to reach a total of 3.35 million tonnes by 2001, valued at over $16 billion. In a new report by Freedonia, it is predicted that the best growth prospects will be offered by reaction injection while foamed moulded polyurethanes, US market

NEW TECHNOLOGY Fluoropolymers can also improve pelletizing output Following long use in improving the production of plastics films, fluoropolymer additives are being developed to improve the output of pelletizing extruders, reported Donald E. Priester of DuPont Dow Elastomers, at ANTEC ‘97, the Annual Technical Conference of the Society of Plastics Engineers in the USA. He reported polyethylene

field trials at a high density a special plant, where

fluoropolymer additive - which he described as an ‘alloy’ of fluoroelastomers and ethylene-based copolymers - was added at a level of 500 ppm into the pelletizing exnuder, together with standard additives. In the first 24 hours, output rose by nearly 15%, with a reduction of 6% in die pressure and power consumption. In contrast to the “prohibitive” cost of using conventional fluoropolymer additives to improve pelletizing, the system costs around $0.01 per kg of HDPE processed, he estimated.

Replacement of HCFCs: the effect on properties Considerable reformulation is needed to optimize polyurethane foam systems with blowing agents replacing HCFCs. This is the conclusion of a US study by Bayer, which sheds some much-needed light on the subject.
