does ptfe tape swell?

No, what you should say is that the raw material belt is polytetrafluoroethylene (PTFE) belt. Its insulation is not affected by environment and frequency. Its volume resistance can reach 1018 ohms. cm. Its dielectric loss is small and its breakdown voltage is high. High and low temperature resistance: little change in temperature, wide temperature range, can use temperature - 190 ~ 260 C. Self-lubricating: With the smallest friction coefficient in plastics, it is an ideal oil-free lubricating material. Surface non-stickiness: Known solid materials can not adhere to the surface, is a kind of solid material with the smallest surface energy. Atmospheric aging resistance, radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged. Non-flammability: Oxygen limit index is below 90. That's what it's all about.
