Fireproofing Material

In recent years, along with development of science and technology, expandable graphite has been applied in fireproofing projects.

This company, based on many years' experiments, has developed fireproofing and flame retardant expandable graphite, which has been put into batch production and have been exported to European and North American markets . This kind of fireproofing and flame retardant graphite is characterized in low initial temperature of expansion (Lowest 90oC for starting expansion), and keep the PH value neutral and stable for longer time.

The fireproofing and flame retardant graphite we produced is the products with lowest initial temperature of expansion and the largest expansion rate fo far among the same products in china.

Sealing strip
Except for the above-mentioned specifications, we are ready to develop new products according to special requirements from customer.

With this advanced fireproofing and flame retardant expandable graphite, we begun developing new fireproof products. At present, we have two varieties: 

Refractory material, Expandable graphite strips, slices, clumps or other shapes, which will be stuck to wall gaps of windowsill, doorslot or various pipelines for expanding upon fire to block the gap, thus isolating smoke and fire, delaying extension of flame and diffusion of toxic gas to gain time for fire fighting and fleeing. This fireproofing blocking material is especially applicable for fireproofing of high building. 

Another product: as an additire put into polymer (plastics, rubber, fiber, textile, and etc.) into fireproofing and flame retardant expandable graphite to reduce inflammability of those materials and possibility of fores..
