Two TPE parts have “virtually unbreakable” seal

Using a new, simplified process, Trelleborg Prodyn Boots is manufacturing aspirated rack and pinion boots made from thermplastic vulcanizate (TPV) for the 2002 Ford Explorer. The company uses Santoprene TPV grade 103-40 from Advanced Elastomer Systems and a press blow molding technique modified for this application.

With this process, an interlocking mechanical bond is formed as the aspirator is attached to the boot. As the two compatible Santoprene parts cool, they form a tight chemical bond. These actions create a virtually unbreakable seal.

“The innovative manufacturing process that Trelleborg Prodyn has developed to attach the aspirator to the rack and pinion boot has enable us to manufacture aspirated boots more efficiently and with superior bonding properties,” says Phillipe Chedru, operations manager of Trelleborg’s Prodyn’s facility in Salisbury, N.C.

Santoprene TPV has been used in rack and pinion boots for more than 15 years, due to the material’s superior chemical and fluid resistance, good compression set, temperature resistance and tight tolerances.
