PTFE BELLOWS
Innoway offers a range of PTFE bellows to be used in special chemical and industrial applications.
Low Pressure PTFE Expansion Joints Type R-LD
PTFE multi-laminated tubes, that ensure an absolute minimum porosity and a homogenous wall-thickness, are transformed again under temperature and pressure to special high-quality bellows, with a high vacuum- and pressure resistance, even during a long period.
