Details

Proven track record at various OEMs for more than 20 years with Arnitel® TPC for inboard and outboard boots, Steering Bellows and Prop Shaft Boots, CVJ and constand velocity joints.

Benefits

• Arnitel® TPC allows for 20-40% lighter solutions than rubber and also more cost effective solutions than rubber
• Arnitel® TPC allows for highly reliable solutions due to its high temperature resistance (more temperature resistance than TPV) and its good resistance against chemicals and greases
