Highly transparent, semi-rigid heat shrink tubing TK20. Thin-walled and resistant. Self-extinguishing. Suitable for higher operating temperatures. Very good mechanical strength. Good chemical resistance. Meets various industrial standards. This heat shrink tubing is used for insulation and protection against mechanical stress, especially at high temperatures. It also provides protection for wire connections and solder joints, as well as for fragile objects such as glass bodies, pipettes, or fluorescent tubes. This is particularly important when chemicals are also used.
