Abstract:
A mechanically compacted composite article comprising a PTFE fibril matrix that entraps particles retains more of its longitudinal dimension, when subjected to mechanical and/or thermal stress, than a similar but non-mechanically compacted article. A method of making a particulate loaded PTFE fibril web is disclosed, the method including biaxial calendaring to form a sheet or sheet laminate, and machanically compacting the sheet or sheet laminate.
