Ingenia develops PE purge compound
Ingenia Polymers Inc. has developed two new purge compounds for a range of polyethylene processing.
Ingenia Polymers 1850 shutdown purge reduces the amount of oxidation of PE and protects equipment during shutdown and start-up. It is designed to cut cross-linking, gel formation and carbonization. The Houston company recommends its use at full strength for blown and cast film, injection molding and blow molding.
The firm's 1851 compound is a pellet containing purge agents. Ingenia touts it as a cost-effective way to clean up equipment and minimize gels and cross-linking. In film and molding equipment it removes degraded PE. It can be used for quick color changes and before manual cleanup. One advantage is that the blown film operator can hold the bubble during the purge cycle when the product is used, Ingenia claims.

Reichhold offering vinyl ester for boats
Reichhold Inc. has developed a vinyl ester resin especially suited to boat building and spa applications.
Hydrex 100-LV provides blister resistance while allowing manufacturers to meet stringent styrene emission regulations. For spa products, the new unsaturated resin bonds well to acrylic sheet. Reichhold of Research Triangle Park, N.C., said the product is pre-accelerated and cures with conventional methyl ethyl ketone peroxide at room temperature.
Hydrex 100-LV's styrene level is less than 35 percent, according to the company. It also has low viscosity and high strength. Reichhold envisions uses such as marine skin coats and complete laminates, spa skins and laminates, and tooling.

Milliken touts agent for clarifying PP film
Milliken Chemical says its development work can expand applications for polypropylene blown film.
Milliken's Millad 3988 clarifying agent is key to the PP film developments. The Spartanburg, S.C., firm said the additive not only boosts film clarity, but it also improves process stability, previously a stumbling block for PP blown film.
The company said that blown film traditionally has been dominated by polyethylene but Milliken's clarifying agent allows production of PP blown film on the same equipment. Since clarified PP blown film has high visual appeal, its use in co-extruded film can eliminate the need for a laminated layer, according to Milliken. Other benefits possible with PP blown film include stiffness and better moisture barrier.

GLS utilizing TPE in Braille keyboards
GLS Corp. of McHenry, Ill., developed thermoplastic elastomers that help vision-impaired people navigate computer systems with Braille aids.
Caprock Manufacturing of Lubbock, Texas, injection molds such parts for the Freedom Scientific Blind/Low Vision Group of St. Petersburg, Fla. A thumb wheel and bezel for Freedom's Focus line are examples of using a material that is soft but with good grip, to make using computers easier. Caprock overmolds Dynaflex TPE based on Kraton to make the parts in Nissei and Toshiba injection presses.

Unistraw will make Sipahh straw in China
An Australian-made polypropylene drinking straw filled with flavoring beads for milk drinks will be manufactured in China.
The product, Sipahh, designed and made by Sydney, Australia-based Unistraw International Pty. Ltd., was launched in Australia in October 2005, boosting milk sales in stores and schools. A Unistraw spokesperson said production capacity in Australia was sufficient to meet current demand, but Sipahh would be launched overseas early next year.
``We will manufacture offshore and locally from early 2006 to meet demand. We've had an incredibly strong start for Sipahh in Australia and we're experiencing week-on-week growth,'' she said.
Unistraw already has partners in the United States, Mexico, Canada, South Africa and the United Kingdom. ``We are finalizing partner arrangements for the key European Union markets and are in discussions with companies in key Asian markets. We have received strong interest from the Middle East, Gulf States and South America, which we will progress during 2006.''
The Unistraw product is a PP straw and filters. Small flavor beads inside the straws infuse liquid as it is sipped. The spokesperson said the straw could be filled with other substances, such as vitamins and pharmaceuticals, for use in the health and fitness industries, and Unistraw is developing other applications. Sipahh is available in caramel, strawberry, chocolate and banana.

Mine project enlists RÃ¶chling PE liner
A low-friction polyethylene liner made by RÃ¶chling Engineering Plastics KG of Haren, Germany, is being used in an Australian mineral sands mining project.
Sydney, Australia-based thermoplastic engineering firm Dotmar EPP Pty. Ltd. prefabricated and installed three liners in 80-ton-capacity conical feed bins.
John Riordan, Dotmar EPP application development specialist, said the linings helped avoid handling problems caused by varying moisture levels in the sand, which disrupted smooth production.
``The polymer liner is specifically designed for lining hoppers, chutes, bins, dump-truck bodies, dozer blades and other applications that require solutions to sliding abrasion and release of sticky materials,'' he said.
The bins are used in the extraction of ilmenite, zircon and rutile from sand to manufacture pigments for plastics, paint and cosmetics.
Riordan said the A$200 million (US$145 million) mineral sands project in Victoria is ``one of the first'' in Australia to use the ultrahigh-molecular-weight PE liners. He would not disclose their cost.

Nestle line to use Plantic bioplastic
Australian biodegradable plastic company Plantic Technologies Ltd. has launched its bioplastic trays in the European market.
Nestle UK Ltd. will use the trays for its Nestle Dairy Box range of chocolates.
The thermoformed trays are starch-based and disintegrate on contact with water. They decompose within three months when left on a compost heap.
Frank Glatz, Plantic's European operations general manager, said Nestle was the first European company to publicly announce its use of the trays. The Plantic product has been sold in the Australian market for two years and Glatz said Nestle's decision to use it validates the benefits of technology to the environment.
``We know people of all ages like to see the tray disappear when it gets wet,'' he said.
Glatz said Plantic, which has subsidiaries in Germany and the Netherlands, expects more announcements of the product's uses. Plantic is working on water-resistant bioplastic trays for wet or moist goods.
