Spacer and support materials

The mechanical properties of thin membranes can be improved dramatically by strengthening them by using a grid material integrated into the membrane itself.
Sefar’s woven, non-shedding monofilament fabrics with large open area are the ideal reinforcement media: these add strength and reduce swelling of the membrane while allowing high throughput rates.
