- Sartomer resin.
Sartomer has introduced what is claimed to be the first commercially available thermoplastic polyurethane (TPU) resin based on unique polybutadiene polyols. The resin, Poly 2035 TPU, is designed to enhance the performance of films, adhesives, sealants, coatings and thermoplastic elastomers (TPEs) when compared to conventional TPUs based on polyether or ......
- New TPU has 'elastic memory.' (thermoplastic
polyurethane)
A novel "shape-memory" thermoplastic resin technology developed by Mitsubishi Heavy Industries Ltd., Tokyo, is in the test marketing stages in the U.S. Mitsubishi's Shape Memory Polymer has several commercial medical industrial and consumer applications in Japan. Two unidentified U.S. firms are seeking FDA approval for extruded prototypes in medical applications....

The slate of key technology developments for the Polymer Div. of Miles Inc., includes recycled RIM polyurethane automotive parts, Class-A SRIM body panels, intensified focus on Apec HT polycarbonate and polymer alloys utilizing thermoplastic polyurethane, and a push to commercialize plastic/metal hybrid structural components. Recent interviews with company executives at ......
- Integral hinges could reduce auto interior costs
Designing plastic parts with integrated hinges formed from the plastic itself is hardly a new idea. These so-called "living hinges" have been around for years on all sorts of packaging and consumer products. But now they show promise for automotive interiors. Engineers at Bayer Corp. have developed a concept for ......
- 20 Thermoplastic elastomers.
The invention of materials that process like thermoplastics but imitate the properties and feel of crosslinked rubbers began in 1958-59 with the commercial introduction of thermoplastic polyurethane and styrenic block copolymers (SBCs). The attraction of simpler and faster processing plus the ability to reprocess scrap gained these materials a permanent ......
- Polyurethane resins.
Cognis has added new products to its Versamid[R] PUR 1000, 1100, and 7000 series of polyurethane resins. Both Versamid PUR 1010 and 1120 are nonreactive thermoplastic polyurethane resins designed for use in flexographic and gravure inks for packaging. They are designed to not cause swelling in flexographic printing plates. Inks ......
- New Grades Improve Weatherability, Molding
Thermoplastic elastomers are copolymers that exhibit advantages of plastics and rubber, usually for specialized applications such as sealing. They are potentially recyclable, yet — like rubber — they are elastic and can absorb shocks. Their ability to stretch and bend without losing properties makes them valuable companions to thermoplastics, which ......
