Products get a grip with launch of new TPEs.

Teknor Apex has launched a new series of 'wet-grip' thermoplastic elastomer (TPE) compounds for injection moulding, which are said to retain a non-slip surface and secure grip even when wet.

The Monprene Wet Grip Series of styrenic block copolymer compounds, which will be introduced by the company at NPE2012, are said to minimise or eliminate the problems encountered with many standard TPEs in soft-touch applications like grips, handles, knobs and cushions.

These products often become slippery and hard to handle when wet from rain, humidity, sweat, dishwater or other common substances. Unlike the standard TPEs, the new Monprene products are said to retain their rubberlike traction when wet, while providing the same elasticity and other key mechanical properties. They are available in hardnesses from 10 to 45 Shore A and, according to Teknor Apex, they can be applied onto a variety of substrates by means of two-shot, coinjection, or insert moulding.

"Teknor Apex has spent more than a year perfecting Monprene Wet Grip Series TPEs so that manufacturers of housewares, appliances, personal care items, tools and sporting goods are able to make their products easier and safer to handle," said Brian Mulvany, Senior Consumer Market Manager. "The proprietary wet-grip chemistry that we have developed addresses everyday situations in the real world, where workers must handle tools, cooks use utensils and golfers grip clubs regardless of surface conditions."

In tests measuring the coefficient of friction of a standard styrenic TPE with a Monprene wet-grip grade, the new compound exhibited a coefficient that was 25 percent greater when surfaces were wet with plain water and 175 percent greater in the case of soapy water.
