HK-G Type Intumescent Firestop Sleeves

HK-G type intumescent firestop sleeve is a kind of rubber and plastic polymer material which applied for Intumex technology to develop successful. When the temperature is up to 180℃, the volume of HK-G type intumescent firestop sleeves will expand quickly and form dense flame retardant carbon layer. So, it can effectively prevent spreading of flame, temperature, toxic gas from cable and pipe sleeves.The structure of HK-G type intumescent firestop sleeve is hollow, it will be convenient to add or replace cables and pipes in the daily maintenance. And it can effectively reduce the overall weight of cable and pipe penetrarions.
Storage and conditions: Dry, and 5-35℃ indoor
