Fluoroplastic composite elastomer

An improved fluoroplastic lined elastomeric tube that can maintain a stable flow rate while pumping aggressive chemicals in a peristaltic pump for an extended period of time and is fabricated in sizes ranging from 0.5 mm to 100 mm in inside diameter. The inner fluoroplastic liner comprises a composi...

Beschreibung
Zusammenfassung:	An improved fluoroplastic lined elastomeric tube that can maintain a stable flow rate while pumping aggressive chemicals in a peristaltic pump for an extended period of time and is fabricated in sizes ranging from 0.5 mm to 100 mm in inside diameter. The inner fluoroplastic liner comprises a composite of expanded polytetrafluoroethylene and a fluoroplastic polymer resulting in improved flex life over single component fluoroplastics. The inventive liner is bonded to either an unreinforced elastomer or a fiber reinforced elastomer for use in both low and high pressure peristaltic pump applications.
