Manufacturing Process

CRP manufactures virgin paste extruded or virgin multi-ply PTFE tubes to guarantee the highest quality from the beginning of the production process.

A unique convolution process undertaken at very high temperatures combined with additional material to compensate for transitional change from straight tube to to convoluted bellows, provides a uniform PTFE wall thickness and a stress-free material in a thermally locked bellows shape. This process has a significant influence on product lifetime performance.
