Wear-, Impact-, and Chemical-Resistant PTFE Sheets
These sheets are manufactured from Rulon PTFE, a PTFE that’s been modified with a filler material. In addition to having the superior chemical and temperature resistance of PTFE, they have excellent impact resistance and a super-slippery surface that resists wear. These easy-to-machine sheets are nonabsorbent, so they won’t swell when exposed to water. They’re also good electrical insulators.
Grade 142 is bronze filled and often used to fabricate linear slides and piston rings.
Sheets with an etched texture have one side that is scuffed to readily accept adhesive; the other side is smooth.
