Flexible Intumescent Graphite Strip smoke seals to fire doors

1. Fire intumescent strip, mainly used in door, wooden doors and door frames, 

between door leaf. When fire Fire intumescent strip will be Automatic inflation, 

sealing the door gap, blocking air circulation between two Spaces, 

effectively prevent fire early smoke, toxic gas and heat and control the harm of human

2.Usage:

It's the basic  material of graphite sealing part. It's maily used to make packing ring,graphite tape,sealing gasket,composite panel mainly used to make car gasket.

 

The product is made from flake graphite with high carbon content which is gone through chemical treatment, expanding under high temperature and then formed by rolling. It owns the characteristics of high temperature resistance, corrosion resistance  and good elasticity. Flexible graphite sheet or roll is the main raw material for making all kinds of graphite tapes, reinforced graphite sheets, sealing and packing gaskets.
