7829170, Nov 9, 2010

Filed:

Feb 16, 2005

Appl. No.:

11/059849

Inventors:

Christopher Bowen - Lincoln University PA, US
Kevin Edward Dove - Wilmington DE, US
Carl Jones - Baltimore MD, US
Raymond B. Minor - Elkton MD, US

Assignee:

Gore Enterprise Holdings, Inc. - Newark DE

International Classification:

B32B 3/22

US Classification:

428 664, 4283155, 524545, 526242, 526250

Abstract:

Improved expanded PTFE materials and improved gasket materials made therefrom, the gaskets being capable of forming a seal with greater bolt load retention than is possible with existing PTFE gaskets. The expanded PTFE membranes of the invention can be tailored to exhibit a matrix tensile strength in at least one direction of at least 25,000 psi, a matrix tensile strength ratio in two orthogonal directions of between 0. 25 and 4, an orientation index of 50 or less, and a density of 2. 0 g/cc or less. The improved gaskets exhibit improved mechanical properties such as high bolt load retention, low creep, high tensile strength, low stress to seal and high crystallinity index.
