    • A polymer coated porous product (20) includes a first porous substrate and a polymer coating penetrating the porous substrate. The polymer coated porous product may optionally include a second porous substrate, and the polymer coating penetrates both the first and second porous substrate. A process and an apparatus for producing polymer coated porous substrate. The process includes overlaying a film of polymer material onto a porous substrate, heating the film of polymer material, and vacuum drawing the heated film of polymer material into the porous substrate. The apparatus includes an extruder (10), means for producing a film of polymer material (16) over a porous substrate, means for heating (12) the film of polymer material and at least one vacuum unit (14). The vacuum unit (14) draws the film of polymer material into a porous substrate (20).
