When storing Pipe linking ptfe tape, do you need to avoid direct sunlight or high temperature environment?

When storing Pipe Linking PTFE Tape, it is indeed necessary to avoid direct sunlight and high temperature environments. Here are the detailed reasons and suggestions:

Avoid direct sunlight
The influence of ultraviolet rays: Although PTFE material itself has excellent weather resistance and UV resistance, long-term exposure to sunlight may cause slight aging of the surface, such as discoloration (yellowing) or surface chalking. Although these changes usually do not significantly affect its sealing performance, they may reduce the appearance quality and service life.
The importance of packaging protection: If PTFE tape is stored in the original packaging (such as aluminum foil bags or opaque plastic bags), it can provide some UV protection. However, if the packaging has been opened or is transparent, it is recommended to transfer it to a light-proof container for further protection.
Avoid high temperature environment

High temperature accelerates aging: PTFE has a melting point of about 327°C. Short-term exposure to high temperature will not directly damage the material, but long-term storage in a high temperature environment (such as over 40°C) may accelerate oxidation reactions (especially in an oxygen-containing environment), resulting in a decrease in the mechanical properties of the material.
Risk of physical deformation: Under high temperature conditions, PTFE tape may become soft and prone to sticking or deformation, which will affect the uniformity of winding during use and thus reduce the sealing effect.
Other storage recommendations
Humidity control: Although PTFE itself has very low water absorption, it may have an indirect effect on the surface properties of the tape in extremely humid environments. Therefore, it is recommended to store PTFE tape in a dry environment and avoid excessive humidity.
Keep away from chemicals: PTFE has strong chemical resistance, but long-term contact with strong oxidants, strong acids, strong alkalis or organic solvents may contaminate the surface or affect its performance. Therefore, it should be stored away from these substances.
Keep in original packaging: Unused PTFE tape should be kept in the original sealed packaging as much as possible to prevent dust, foreign matter adhesion or accidental damage.

If you plan to store it for a long time (more than 1 year), it is recommended to check the condition of the tape regularly to ensure that there are no problems such as embrittlement, deformation or contamination.
