Клей подкладке труб Защита

Have properties of excellent insulating ,environmental sealing,and resistant to impact and abrasion.Designed for application to seal and protect electrical and communication connections, providing excellent mechanical protection to cable joints and terminations.High shrink ratio allows it easily fit over irregular shape and large connectors. BTDW-HA is recommended toapplications for light cable and wire harnesses,where requiring waterproofing, protection of connector components, and thus encapsulates and seal components contained within the tubing.
