- Combining rubber and plastic in one-step
A new manufacturing process has been developed by Advanced Elastomer Systems, Brussels, Belgium, and Paul Troester Maschinenfabrik, Hannover, Germany, to mesh Santoprene thermoplastic vulcanizate and EPDM rubber into profiles or weatherseals for automotive and building industries. The single step coextrusion process uses a 60-mm plastic extruder for the Santoprene and ......
- TPV for automotive weatherstrips
The Sarlink 5000 Series of thermoplastic vulcanizates (TPV) combines high elastic performance with high UV/color stability. It is designed for major automotive applications, such as weatherstrips and interior trim. Automakers can use Sarlink 5000 in all thermoplastic seal design, or they can coextrude it on top of EPDM to add ......
- High-performance TPEs
Basics of design engineering Materials From Multibase, a Dow Corning Co., Saint Laurent du Pont, France (www.multibase.com), comes TPSiV thermoplastic elastomers, which combine the high-temperature elastomeric performance of silicone rubber with the melt reprocessibility and chemical resistance of engineering thermoplastics. The abrasion-resistant materials feature a range of hardnesses from 50 ......
- TPE auto weather seals.
Weather seals fit all the doors and windows of every automobile on the road. Among the jobs they do is to keep the inside of the car snug and safe from wind, rain, or carwash suds. Think how many seals there are. Approximately 95 percent of the weather seals in ......
- New resins make their debut at NPE 2000
A new family of thermoplastic-metal composites, Polymetals, are poised to replace lead and other high-gravity metallics. Potential uses include radiation shielding for nuclear medicine, medical imaging, and radiation therapy; weighting and ballast applications for industrial machinery, sporting goods, and instrumentation; and nontoxic projectile inserts for small-caliber ammunition. The high-density composite, ......
- EPDM Masterbatches Aid TPV
Compounders.
A new line of EPDM rubber masterbatches is designed for use by compounders of thermoplastic vulcanizate (TPV) elastomers. Kelprox XL from DSM Elastomers, Leominster, Mass., combines DSM's Keltan EPDM with its Sarlink TPV know-how. The result is rubber masterbatches that are already dynamically vulcanized. Since the rubber in Kelprox XL ......
- New Elastomers Boast Enhanced Properties
Newton, MA—We normally like to avoid the quips about elastomers "stretching" beyond their limits. But we won't— because that's exactly what has happened with three new elastomers that tackle the shortcomings of previous materials. One of them takes thermoplastic urethanes (TPU) into softer territory. Another strikes a better balance between ......
