medium wall black heat shrink sleeve for pipe joint
Description
Medium wall heat shrinkable tubing (MHST-A) is a tubing with hot melt adhesive, having properties of excellent insulating, environmental sealing, and resistant to impact and abrasion. It is designed for applications to seal and protect electrical splices, cable terminations and joints where electrical insulation and water proof are required. 3:1 shrink ratio allows it easily fit over irregular shape and large connectors.
Features
>Resistant to UV-radiation
>High electrical insulation
>Superior mechanical property
>Minimum fully recovery temperature: 120°C
>Standard color: Black
