Zhongshan Lianheqiang Rubber And Plastic Technology Co. Ltd
In addition to the usual sealing, durability, and energy-saving features, modern building sealing strips increasingly focus on the overall fire prevention and flame retardant safety of buildings. By designing fire escape routes and partition areas and selecting appropriate materials and flame retardant grades for sealing strips, various fire safety requirements can be met!
General flame retardant silicone rubber, suitable for ordinary fire prevention requirements.
Comparison diagram of special fireproof silicone rubber before and after burning, suitable for relatively enclosed spaces or core areas of public buildings with high safety requirements.
