PORON® Dura-Shape® Materials

By adding the PORON Dura-Shape option, PORON materials are enforced with a tough polyester film securely bonded between two layers of foam. This option is available to all PORON® 4701 foams, as well as the PORON® 4790-92 foam. PORON Dura-Shape technology increases the polyurethane’s dimensional stability while maintaining the compressibility characteristics of the original material, providing engineers stability for their gasket design needs.

Features

Increased dimensional stability
Tougher tear strength
Functional performance across a wide range of temperatures
