HK-M Type Intumesent Firestop Sealant

HK-M type intumescent firestop sealant  is a new expandable flame retardant products developed by intumex technology. When the  temperature rises to 180℃, the volume of the sealant will expand quickly ,then harden to dense porous carbon layer flame retardant. The expanded flame retardant layer fills the gap between cables and pipes, and become a kind of fireproof protective layer. 

Storage condition: Dry, 0-30℃ indoor. 

 

Technical Index:

Base material……………………………………………………………………Neutral silicon

Oxygen index ……………………………………………………………………≥40

Thermal expansion rate …………………………………………………………≥5

Applicable temperature …………………………………………………………-60℃ - +90℃ 

No corrosion and no swelling to copper, aluminium, steel, plastic, and rubber


Technical Features:
1. After the finished sealant is solidified, it can form elastomer for fireproof and sealing, and it's convenient for us to replace or add extra cables and pipes in the later period.

2. The solidified sealant is neutral and free halogen, and it doesn't have bad effect. For example,  it can't  corrode cables and pipes, metal frame and PVC material which is contacted.

3. It won't produce corrosive, halogen, acid gas after the sealant is solidified. And it won't produce secondary pollution for electrical equipment.  

4. After the finished sealant is solidified, it has excellent bonding behavior with cables, pipes and metal. And it can ensure the water tightness and gas tightness of the fireproof system.

5. The polymeric elastomer can support the frequent vibration and a certain amount of displacement which are from cables and pipes. It's more suitable for construction requirements on site.
