RDN four-belt puller offers speed options
RDN Manufacturing Co. Inc. said its Model 440 four-belt puller is designed for heavy-walled profile and pipe in diameters from three-eighths inch to 12 inches.
The puller actually can operate using either four belts, or just two.
A 3-horsepower, alternating-current, flux-vector drive ensures a steady, stable pulling force. A 5- HP drive is optional. A four-speed transmission drives a gear reducer on each belt assembly, with a continuous roller chain. That gives the puller a higher level of torque over a wide range of speeds, said RDN, based in Bloomingdale, Ill.
The 440 uses non-marking, ``V'' groove belts made from solid neoprene.

New Bayer PC slated
for auto interiors
Bayer MaterialScience LLC has developed a new grade of polycarbonate for automotive interior applications.
Bayblend LGX 300 is a PC blend low in gloss and with a high melt flow, allowing it to replicate different types of surface finishes for glove-box doors, door trim, knee bolsters and other components. The Pittsburgh company also said the new blend has higher heat performance, and better impact, scratch and mar resistance compared with polyolefin materials.
In addition to weather resistance, Bayblend LGX 300 is a low-emission formulation designed to reduce levels of volatile organic chemicals in auto interiors.

New foam stabilizer
enables thick sheets
Rohm and Haas Co. has developed a foam stabilizer for cellular PVC trim board.
ParaloidT SureCelT can cut material usage by 10-15 percent, the Philadelphia firm claims. It gives even expansion and high cell uniformity across wide-sheet dies. It also makes it possible to extrude very thick sheets to lead to new product opportunities.
Rohm and Haas said cellular trim board usage is growing because of its low maintenance, resemblance to wood and high durability. The new additive contributes to lower gloss for enhanced paint adhesion. Its formulations exhibit good viscosity and are easily substituted in existing formulations, the company said.

Extrusion aids limit
World Minerals Inc. launched two extrusion aids for PVC.
Europerl 60 and Harborlite 205P are fine grades of alumino silicate that reduce die buildup and plate-out on the extrusion line. They also improve overall quality and surface finish of the extruded part.
The Santa Barbara, Calif., firm said the products allow longer production runs with fewer stoppages for cleaning. They inhibit buildup of hard deposits caused by minerals and softer, organic buildup associated with waxes. World Minerals claims they work with a variety of stabilizer systems, and with rigid and flexible formulations.
The additives are especially suited to pipe, door and window profiles, siding and other high-output extrusions.

New Riteflex grades
free from halogens
Ticona Engineering Polymers has developed new resin grades that address concerns about halogen content.
Two new Riteflex thermoplastic polyester elastomer grades in its XFR series of flame-retardant materials are halogen free. The grades are designed for applications where elasticity is balanced with enhanced toughness.
Riteflex XFR 440 has Shore D hardness of 40 while XFR 655 has Shore D hardness of 55. Key properties of the two materials include flame retardance, comparative tracking index of more than 600 volts, good processability and high tensile elongation.
Ticona also says its new grade of Fortron polyphenylene sulfide has reduced levels of chlorine in its formulation. This will help electrical and electronic component manufacturers to design and make products that comply with anticipated halogen-free industry standards.
Fortron PPS 1140A66 combines improved polymerization and compound technologies to reduce chlorine concentrations to below 900 parts per million, the Florence, Ky., company claims. The reduction is accomplished without a loss of the mechanical properties that make PPS well-suited to connectors, switches and other electrical components. As well, the material meets the UL94 V-0 flammability rating without the addition of flame retardants, according to Ticona.

Welding unit boosts interchangeable tool
MS Plastic Welders LLC of Fowlerville, Mich., has introduced a flexible ultrasonic plastic welding machine with a tool-change system, called MS Cartridge.
The machine is designed to join two parts, such as automotive door side panels and consoles. An interchangeable tool cartridge lets the user remove a tool and change to another one in less than five minutes useful for short-run welding jobs, or for a variety of applications at different times on a single welder.
MS Plastic Welders said the machine allows processors to make service parts, when necessary, to meet demands of the auto industry, rather than bring out a machine to weld parts on occasion.
The company, a subsidiary of Germany-based Maschinenfabriken Spaichingen GmbH, makes machines for ultrasonic staking and ultrasonic spot welding, heat-contact welders, and energy-directed welding, which uses rib melts to bond two parts.
