Chemically inert, PTFE has multiple applications and can replace polypropylene
in applications requiring compatibility with a large variety of chemicals.
PTFE syringe barrels do not swell in solvents like polypropylene does,
especially in solvents such as dichloromethane, tetrahydrofuran, and dioxane. The
PTFE plunger seal stays consistent after hours of exposure.
