Dow's Momentum going commercial Dow Chemical Co. is making its Derakane Momentum epoxy vinyl ester resins commercially available to all fabricators of fiber-reinforced plastics.
Mark Sullivan, global industry manager for composites, made the announcement June 1.
Dow began Momentum validation trials in May 1999 at customer sites, including about 30 in North America and 50 in Europe. According to Dow, processors save because the new resins react better, work easier, cure faster and use less cobalt naphthenate as a promoter than with existing epoxy vinyl esters.
"We've asked them to share the savings with us," Sullivan said. Customers giving Dow an increased share of business can buy Momentum resins "at a competitive price." Those not participating will pay more.
Sullivan declined to identify differences but said Dow is not changing the chemical backbone or structure.
"You can continue to specify Derakane or Derakane Momentum, and [there is] no change," he said. Municipal codes and others often specify a Derakane product, and administrators can resist what they perceive as a substitute with a different number.
Initially, fabricators did not believe they could save on cobalt, he said.
"If they work with us incrementally and get to the end point, people are coming out to [saving] 3 cents per pound on costs. We have to prove it and show them it works."
Existing Dow vinyl ester plants in Joliet, Ill.; Sarnia, Ontario; Rheinmunster, Germany; and Guaruja, Brazil, will have capability to make the new material.
In a related development, Dow is launching on June 5 a Derakane Web site with an interactive corrosion recommendation database, other technical information, news and online resources.
Momentum's availability is seen as progress for Midland, Mich.-based Dow. John Roberts, an analyst with Merrill Lynch Co. in New York, said in a telephone interview that 2000 is turning out to be a good year for Dow. He cited "some evidence of share gain in basic plastics as well as lots of new products, of which this would be one."

Military targets TES's PVC toilets for troops
GEORGE TOWN, AUSTRALIA — U.S. and Canadian military forces may follow the Australian and United Nations' lead by using a Tasmanian firm's in-field, portable PVC toilets.
George Town-based Tasmanian Environmental Solutions Pty. Ltd. created the PVC toilets, named BIPUs, and already have supplied 150 to Australian and U.N. troops in Dili, East Timor.
Mike Turner, TES international director, said the BIPUs, or bioremediation in-field personnel units, already have been exported to New Zealand, South Africa and Uganda. North American forces still were inquiring, he said.
BIPUs are similar to septic tanks in that they naturally decompose sewerage. BIPUs pass the sewerage through a series of trenches and lined PVC chambers installed underground.
Using PVC means the chambers can be folded and transported flat, Turner said. The units took almost a year to create, from design to approval. The Tasmanian government approved BIPUs for use last September. They can be used for field hospitals and farm, residential, community, remote forestry, sporting, humanitarian and tourism facilities.
Each BIPU costs A$3,000 (US$1,721), including installation.
The units helped stop the spread of a cholera epidemic in Uganda in 1998 which killed 127 children. BIPUs replaced defective pit toilets which flooded after heavy rainfall, causing the disease outbreak.

Cool Polymers debuts conductive polymer
Cool Polymers Inc. has developed a thermally conductive polymer for heat sink applications.
The Warwick, R.I., firm said CoolPoly is 100-500 times more thermally conductive than standard plastics. It can be injection molded to replace nonconductive plastics and metal parts in electronics, medical, automotive, lighting and industrial equipment.
Cool Polymers claims CoolPoly's heat transfer is similar to that of aluminum and other metals, but it weighs 40 percent less than aluminum. It is composed of mainly non-metallic reinforcements, such as carbon and ceramic, in an engineering resin matrix.
Other properties that promise broad application are low coefficient of thermal expansion and elimination of hot spots to provide better dimensional stability.

Unit offers uniform surface treatment
Plasmatech Inc., which makes surface-treatment equipment, said its V55-GKM Low Pressure Plasma System now has a rotary drum for handling a large volume of bulk plastic parts.
Plasmatech of Erlanger, Ky., will display the V55 during NPE 2000.
The machine modifies the surface of plastic parts to increase adhesion properties before bonding, printing, coating or painting. The rotating drum ensures uniform treatment of thousands of parts. The drum can be removed, opening up a larger chamber to process larger parts.

Technology cuts firm's printing costs
Composite Technologies Co. LLC has cut printing costs in half with new graphic technology that converts computer images to plate images without having to go to film.
The Dayton, Ohio, firm uses a four-color offset press with fade-resistant inks and varnish. The graphics are suited to injection molding, structural foam molding and vacuum forming.
Composite Technologies makes compression molded thermoplastic and thermoset composite parts for sports, beverage and other industries.

NDC measuring probe smaller, priced lower
The AccuProbe from NDC Infrared Engineering is a slimmed-down, lower-priced version of the gamma-gauge used to measure the thickness of blown film at the bubble, or on the layflat area.
The flashlight-sized probe measures from only one side of the film. When it is mounted on the collapsing frame, it is possible to obtain a true profile of the thickness around the bubble, the company said.
NDC Infrared Engineering, based in Irwindale, Calif., is a unit of the Fairey Group.

AET Films introduces OPP packaging films
AET Films introduced two oriented polypropylene films for baked-goods packaging.
The films, called FAST and BCH, are designed for single-web plain or surface printed packaging. They are one-side sealable, one-side treated materials for use with solvent-based inks. FAST has good slip and hot slip properties for high-speed horizontal packaging systems. BCH, also for horizontal packaging machines, has good slip and hot-tack performance and stability over a wide range of printing temperatures.
