Expanded 2mm PTFE Sheets

EPTFE (Expanded PTFE) is a Universal sheet EPTFE gasket material for most services. It seals rough and irregular surfaces. Expanded PTFE is made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness. Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed. It is chemically resistant over the 0-14 pH range. Specific gravity: 4 to 6. Suitable for temperatures to 600°F.
