Product characteristics of fire-proof expansion rod: high rate fire-proof expansion graphite rod can rapidly expand to 15-30 times of its original volume in case of fire and heat, and it is used for filling cavities of aluminum alloy profiles and plastic steel profiles. Auxiliary fire protection system to achieve fire integrity.

Specification: expansion rate 60, 100, 200, 250, 300 ml / g

Performance: it has good plasticity, flexibility, ductility and sealing. The product has the following characteristics:

(1) It has high temperature resistance, high pressure resistance, corrosion resistance and radiation resistance.

(2) Under harsh working conditions, it has the characteristics of no decomposition, no deformation, no aging, no deterioration and stable chemical properties.

(3) It has certain elasticity and flexibility. It is a new sealing material instead of rubber, graphite, fluoroplastics and other traditional seals.

(4) Because of its large expansion coefficient and short expansion time, it can be used as the necessary material for various metallurgical powder, fire-retardant ring, fire blanket, fireproof cloth and fireproof coating, etc.
