Modified PTFE: Hoses with optimized properties
In addition to the above-mentioned outstanding advantages of conventional PTFE for our hoses, there are, however, certain limitations to which the material is subject. The most significant are:
- A tendency to cold flow
- Poor to no weldability
- Lack of radiation resistance
- Milky, opaque surface
PTFE hoses with PPVE content for better weldability
In order to optimize the properties of a conventional PTFE hose, the modifier perfluoro(propyl vinyl ether) (PPVE) is incorporated into the linear chain of the PTFE. The proportion of this exceptionally thermostable material is below 1%, so the proven chemical and thermal properties of the standard PTFE are almost completely retained.
The resulting advantages are considerable:
- Better weldability
- Denser polymer structure
- Lower permeability
- Higher transparency
- Less deformation under load
These improvements make it a dependable material for all applications where only the best is good enough. Areas of use of modified PTFE are mainly:
- Vehicle construction and aviation
- Electrical industry
- Chemical plant construction
- Semiconductor industry
Other PTFE hoses to order
We offer versatile PTFE hoses for a wide range of applications, such as heatshrink tubes that can be expanded and re-shrunk, or hoses made of thermo fluoroplastics, which can theoretically be produced in unlimited lengths. In addition, we manufacture individual PTFE hoses according to customer requirements, for example with printing and laser-assisted engraving.
If you have any questions or special requests, please do not hesitate to contact us.
