Promising cushion-like indentation that’s associated with foamed structures, a new high-flow thermoplastic vulcanizate (TPV) also offers cost-reduction opportunities and good surface qualities for automotive interiors.

ExxonMobil Chemical’s Santoprene TPV 8211-85 M350 reportedly provides low and stable gloss level; high scratch- and mar-resistance; good abrasion and chemical resistance; and low fogging and odor emission. The elastomer is colorable and can be used for door panels, center consoles, lower instrument panels, back seat covers, and B and C pillars.

To achieve “comfort touch,” Santoprene TPV M350 can be processed using two-component injection molding or mono-sandwich molding onto a rigid polypropylene substrate for an unfoamed structure that does not indent. Either way, ExxonMobil Chemical says the result is an over-molded TPV skin with a soft touch. A thermoplastic, the TPV also has what the company calls “sustainability opportunities” because less labor and time are required for production, with reduced scrap and improved recycling. —[email protected]
