Expanded PTFE

Polytetrafluoroethylene (PTFE) Mesh

Expanded PTFE mesh is ideal for high temperature and highly caustic environments. It is chemically resistant, non-stick, and UV stable. Some key features include:

• Non-toxic
• Low friction
• High anti-adhesiveness
• High dielectric properties
• Suitable for continuous use from -100°C up to 260°C (500°F)

Expanded plastic mesh is produced by slitting plastic sheet stock in a controlled pattern, then stretching or expanding the width to produce the designated nominal aperture (hole) size. Tolerances vary with apertures (hole sizes), weights, thicknesses, and widths. PTFE Mesh is sold by the lineal foot. We do the cutting to your custom requirements! Please consult an Industrial Netting representative to determine the suitability of these products for your intended use.

PTFE products are stabilized to control open area percentages. As product thickness increases so does the likelihood of shrinkage in applications where temperatures are elevated.

Diamond Mesh Netting will stretch under tension causing the hole shape to elongate in one direction and narrow in the other. This "accordion effect" causes the tensioned dimension to shorten and the perpendicular dimension to grow as material relaxes. Tolerance only applies at time of cutting.
