Applications
Heavy Wall Heat Shrink Tubing have properties of excellent insulating, environmental sealing, and resistant to impact and abrasion for applications to seal and protect electrical and communication connections, providing excellent mechanical protection to cable joints and terminations, 3:1 shrink ratio allows it easily fit over irregular shape and large connectors.
WHST is recommended to apply for light cable and wire harnesses, where requiring waterproofing, protection of connector components, and thus encapsulates and seals components contained within the tubing.
Features
>Resistant to UV-radiation
>High electrical insulation
>Superior mechanical property
>Minimum fully recovery temperature: 120℃
>Standard color: Black
