MATERIALS: Higher Prices for PBT, TPU, Nylon, Thermosets & More
WEB EXCLUSIVE: This month, prices are due to rise for engineering thermoplastics, composite thermosets, and UHMW-PE:•DSM Engineering Plastics said it would hike nylon 6 resins early this month by 12¢/lb, following a similar move by BASF in March.
WEB EXCLUSIVE: Even before the effect of Middle East unrest on oil prices could ripple through the petrochemical/plastics industry, fresh price hikes were announced for early March in nylon, polyolefin wire/cable compounds, and thermoset polyesters.
WEB EXCLUSIVE: May will see a number of price hikes in nylons, styrenic block copolymers, and thermoset (unsaturated) polyesters:BASF hiked nylon 6 by 5¢/lb on May 3, while DSM raised nylon 6 extrusion and compounding grades 10¢ on May 1.
A new series of DCPD polyester casting resins are said to accept higher filler loadings to reduce costs for cultured marble manufacturers by at least 11%. Vicast A830 resins from AOC, LLC, Collierville, Tenn., have lower viscosity than standard polyesters with the same styrene content (29-32%), typically 150 to 250 cps vs. the usual 1100-1200 cps.
The world’s growing appetite for wind energy is transforming wind blades into one of the hottest composite applications around. The huge build-up of wind-power generating capacity—particularly in the U.S, China, and Spain—has raised a bumper crop of new plants for manufacturing these composite parts.
A new elastomeric bisphenol-A vinyl ester features high elongation and toughness for ballistic protection in military vehicles.
One year after EPA’s MACT rules took effect, most FRP fabricators have complied via process modifications or low-styrene resins. But some big players have invested in much more elaborate technology.
The Metro Water Reclamation District in Denver has installed 500 ft of what is believed to be the largest composite sewer pipe in North America.
A unique research collaboration has resulted in the development of interrelated technologies that allow sheet molding compound (SMC) to be powder primed.
PUR lumber and utility poles challenge standard thermoplastic and thermoset composites. Other show news included ‘tool-less’ molding and new resins and equipment.
Making high-strength composites less expensively was the dominant theme of the recent Composites 2003 Show in Anaheim, Calif., sponsored by the American Composites Manufacturers Association (formerly the Composites Fabricators Association). Among the stars of the show were the vacuum infusion process (VIP), along with a number of new resins—including several non-traditional material chemistries—and new initiators. (New reinforcements, fillers, additives, and equipment will be covered in future articles.)The closed-mold VIP method is attracting a growing following from spray-up fabricators who want to meet the EPA’s MACT (Maximum Achievable Control Technology) standards for hazardous air-pollutant (HAP) emissions, which take effect in 2006.
