A method for producing a multi-component. porous PTFE article comprises the steps of bringing components of PTFE containing a liquid lubricant into intimate contact with each other, removing the lubricant and stretching the composite article in one or more directions. The PTFE components may optionally contain a filler. The resultant product has a virtually uninterrupted structure at the bond between its components and possesses very high bond strengths. |
