- 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 ......

Tires for hand trucks, wheelbarrows, and beach carts are soft and fat, giving them the flexibility to negotiate soft sand, muddy turf, and uneven terrain. Roleez Wheels Inc. of Benicia, Calif., used to make those kinds of inflatable balloon-type tires of polyvinyl chloride, but then decided it needed something tougher, ......

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 ......

Japanese elastomers bounce to Texas Styrenic elastomers from Japan will soon become more widely available in North America. Through its Septon America subsidiary, Kuraray Company Ltd. next month opens a production and technical service facility near Houston, TX. There, the company will produce a wide variety of styrenic block copolymers—not ......

Structural RIM takes on established composites Reaction-injection-molded (RIM) polyurethanes haven't always been lumped in with conventional composite materials like polyester FRP and SMC. Yet with the addition of reinforcements, RIM materials can take on traditional composites in a variety of applications. According to Harry George, manager of Bayer Corp.'s specialty ......

- 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 ......
