Top 4 Ways to Prevent The Aging of PTFE Tubes

Nowadays, many products stand out in the development of technologies and industry, and best PTFE tube is one of these products that play an important role in various fields. But have you ever noticed the aging of PTFE tubes? The performance of PTFE tubes will also be reduced after aging. So a series of measures should be taken to prevent the aging at the later stage of the production of PTFE tubes. The aging of PTFE tubes is natural and cannot be prevented, but the only thing you can do is to slow the aging speed of
PTFE tubes. To help slow down the aging rate of PTFE tubes, you should strengthen maintenance in using PTFE tubes and take a series of measures to prevent this situation. Here Suko offers you the major four methods to slow down the aging speed of your PTFE tube.

1. When choosing the sizing material of PTFE tubes, you should use sulfur curing system whenever possible. Due to the heat resistance of its vulcanized rubber, it can be modified by reducing or avoiding the use of elemental sulfur, which can minimize or remove polysulfide crosslinks and produce mainly monosulfide or disulfide crosslinks, thus slowing down the aging of teflon tubes.

2. To ensure that the material achieves the desired heat resistance, the use of peroxide is required. In this case, peroxide vulcanization produces carbon with better thermal stability and carbon cross-linking bonds.
PTFE tube manufacturer also notes that you should pay special attention to other additives in the use of peroxides. For example, the choice of antioxidants needs to be more stringent, as many of them interfere with the vulcanization of peroxides. Therefore, you can also use paraffin oil, an effective additive that will not interfere with peroxide vulcanization.

3. In addition, in order to prevent the partitioning of the peroxide cation and avoid too low vulcanization of the high-pressure hose (indicated by lower hardness, lower modulus and higher compression and long-term deformation), you should use peroxide to reduce the amount of acidic filler. If possible, the addition of alkaline compounds (e.g. zinc oxide or magnesium oxide) usually improves the cross-linking efficiency of the peroxide.

4. When producing best ptfe tubes, some additives can be added, such as antioxidants, and alkaline compounds, etc., so as to improve the cross-linking efficiency of peroxides and delay the aging of teflon tubes.
