New TPEs: Not Slippery When Wet

A new range of functionalized TPEs is designed for improved wet-grip performance.

A new range of functionalized TPEs is designed for improved wet-grip performance. RTP 6011 from RTP Co., Winona, Minn., is claimed to have 45% higher wet coefficient of friction (COF) than SBC-based TPEs and olefinic TPVs of equivalent hardness. The wet COF of these new products is equal to or higher than dry COF, whereas most TPEs exhibit a significant decrease in COF when they become wet.


Based on reportedly unique TPE technology, RTP 6011 is offered in 55, 65, and 75 Shore A hardness and can be precolored or colored by a concentrate. Customized grades and colors are available, and the material is bondable to PP. In addition, RTP is developing products that bond to other substrates.
