Firm touts MedGuard as PVC alternative
Cooley Specialty Products has debuted a polyolefin-based compound designed to replace PVC in medical membranes such as blood bags, tubing and curtains.
The Pawtucket, R.I., firm said its Cooley MedGuard is flexible, it can be incinerated and it is weldable by ultrasonic, hot air, radio-frequency and other methods. Cooley claims the new material performs as well as PVC-based products in medical flexibles and is less costly and easy to dispose.

New PET compound has UV protection
Voridian has developed a PET compound with ultraviolet-light protection for custom packaging applications.
The division of Eastman Chemical Co. said Vitiva PET is a drop-in replacement for standard PET while offering high performance and crystal clarity for packaging food, beverages, cosmetics and other products. One version, Vitiva PET PC715, has an approved UV absorber that protects delicate colors, flavors and vitamins.
Voridian claims its new resin family blocks UV light with wavelengths from 320-370 nanometers, while standard grades of PET and other resins and glass don't stop the damaging rays. The Vitiva materials are blow molded efficiently and produce no plate-out, according to the Kingsport, Tenn., company.

Axel Plastics offers streak-free sealer
A new mold sealer provides easy, streak-free application for reinforced-plastics processing, according to Axel Plastics Research Laboratories Inc.
Axel said its Xtend S-19B is a low-viscosity liquid that can be applied at ambient temperature and needs no wipe-off or polishing when it has dried and cured. The Woodside, N.Y., firm claimed the sealer provides a glossy Class A finish while improving styrene resistance and release of low-volatile gel coats.

SIG receives orders for Plasmax process
PET blow molding equipment supplier SIG Corpoplast GmbH said it has orders for its Plasmax barrier coating process, which last year won approval from the Food and Drug Administration.
SIG of Hamburg, Germany, jointly developed Plasmax with Schott HiCotec of Mainz, Germany.
Plasmax uses plasma impulse chemical vapor deposition to coat PET bottles, significantly reducing the penetration of oxygen or the loss of carbon dioxide and boosting the shelf life of the contents.
A Swiss juice bottler, Bischofszell Food Ltd., is using an industrial-scale prototype of Plasmax. The company can run 10,000 PET bottles per hour through the coating machine. In Japan, Hokkai Can Ltd. of Tokyo has installed a Plasmax line. SIG said Hokkai is the largest global producer of plasma-coated PET containers.
SIG was scheduled to deliver the line to Hokkai early this year. Hokkai is interested in using Plasmax for hot-fill bottles, food, beer and other applications.
SIG's U.S. headquarters, SIG Plastics Technologies (USA) Inc., is in North Branch, N.J.

Linden introduces rear-foaming tech
Linden Industries Inc./EMB, which makes polyurethane equipment, has introduced a new way to make leather automotive instrument panels and interior components for the North American market.
The ``rear-foaming'' technology was developed by Isotherm AG, a Swiss equipment maker, and Elastogran GmbH, the BASF Group polyurethanes materials business.
The traditional method for making leather automotive components is a labor-intensive, multistep process that has higher reject rates, Linden said. With the new process, the leather is positioned into the mold and the substrate is sprayed with a layer of PU foam, which then is compressed into the leather to produce the finished part. The new method eliminates the need for backside coating and seam sealing, cutting cycle time and reducing operator labor.
The rear-foaming process uses existing tooling, according to Linden, in Cuyahoga Falls, Ohio.
