Addisperse stabilizer improves foam parts
Additives producer Addisperse Inc. has developed a foam stabilizer that improves properties of foamed parts.
Foamaid FA-101 controls the release of volatiles during processing and during chemical or physical foaming. It allows more control and a finer cell structure that gives a high-quality surface.
In vinyl extrusion, the product reduces or eliminates yellowing at the core of thick foamed extrusions by controlling volatiles. It helps eliminate voids, improves melt stability and reduces plate-out, according to the Bensalem, Pa., company.

Paper bottle gets assistance from PLA
It's being marketed as an environmentally sensitive attempt to address the 60 million plastic bottles thrown away daily in the United States. Brandimage's 360 Paper Water Bottle was a recent finalist in the ecodesign category of the Industrial Designers Society of America's International Design Excellence Awards '08.
Yet the concept from the international design firm Brandimage - Desgrippes & Laga does not abandon plastics completely it incorporates a micro-thin layer of barrier film made from polylactic acid.
The package in the awards submission, a 12-ounce, single-serve bottle consists of two halves of paper sheet stock made from materials such as bamboo or palm leaves. When joined, the halves encapsulate the PLA film in an oval-shaped bottle with a flange running around the container.
In a Dec. 11 telephone interview from the firm's New York office, Jim Warner, managing director of industrial design, said he is not out to drive plastics processors out of business.
``We need PLA in the 360 bottle,'' he said. ``It contains the liquid and provides the barrier, but it provides no structural integrity.''
In the design, the barrier material acts as the means to fuse the two halves together. Consumers tear off the top to open the container. Instead of discarding the closure, the user peels it in half: One half contains a plug-fit side and caps the bottle; the other half gets tethered to the bottle's integral finger loop to eliminate litter.
``We think there's a positive effect in the current economic environment,'' Warner said. ``If there's ever an inference of waste, or an inference of spending more for something that you really didn't want [in packaging], this plays into that.''
Designers envisioned self-bundling six-packs to eliminate the use of separate carriers. For shipping and packaging, they created an all-natural structural board running between two vertical ends with snap-off stanchions to reduce materials and enable self-merchandising, he said.
Cincinnati-based Brandimage does not have a converter to mass-produce the 360 bottle, Warner said, but is in talks with potential partners.
``We're trying to find a branded home for this,'' he said. To that end, Brandimage has three employees whose time largely is devoted to answering inquiries about the 360 bottle, he said.

Bayer's nanotubes gain EPA approval
Bayer MateralScience LLC has obtained regulatory approval from the U.S. Environmental Protection Agency for its multi-walled carbon nanotubes.
The approval allows the Pittsburgh company to sell the product on the U.S. market. Approval covers Baytubes C150P and HP grades made in Laufenburg, Germany, in a 132,000-pound-per-year plant.
Baytubes can be added to polymers to improve mechanical strength and antistatic properties. Epoxies, thermoplastics and coating systems use the nanotubes in products ranging from sporting goods to wind-turbine rotor blades.

Recycled PET sheet has virgin qualities
Invista Sarl has debuted a rigid PET film and sheet that contains up to 25 percent post-consumer recycled content yet features color, clarity and processability of 100 percent virgin PET sheet.
Performat-R is based on repolymerized PET from recycled resin converted back to prepolymer feedstock. Therefore, it does not contain imperfections of conventional recycled PET sheet, according to the Wichita, Kan., firm. Clarity and brittleness properties are similar to those for amorphous-PET sheet, Invista says.

Ampacet's additive boosts color palette
Ampacet Corp. has introduced a color-leveling additive for package designers.
The Tarrytown, N.Y., firm said ProBlend allows a single machine setting that can accommodate all colors, giving designers a broader palette of color possibilities. Ampacet claims the product can reduce cycle times, increase production efficiency, and give higher quality output and cost savings.
Ampacet said with ProBlend all colors can run at the same line speed without affecting shrinkage or quality. Running different colors at the same speed traditionally can cause tolerance variations that may lead to container leakage. ProBlend works especially well in polypropylene closures, tubs and containers.
