ZIMFLEX grasshopper hose 905S and 906S flame retardant anti-static hose, its material is PU steel wire hose, with wear-resistant characteristics, suitable for conveying granular materials. 951FR flame retardant hose is made of PVC plastic pipe, suitable for ventilation and dust collection. Grasshopper flame retardant hose hot section is 502, the material is silica gel coated glass fiber cloth pipe wall, wrapped around spiral steel wire reinforcement, suitable for ventilation places. The flame retardant effect of flame retardant hose is also graded, so what if the grade is determined?
B1 and B2 refer to the flame retardant standards V0,V1 and V2. The flame retardant grades are the flame retardant grade determination methods in UL94, and A1,A2,B1 and B2 are the flame retardant grade determination methods in German standard DIN4102. V0 flame retardant grade * *,V2 flame retardant grade * *,A1 flame retardant grade * *,B2 flame retardant grade **UL94 is mainly aimed at testing the flame retardant performance of plastic parts in electronic products, DIN4102 is the flame retardant performance test standard for building products. The B1 grade extruded board self-extinguishes after three seconds from the fire, and the B2 grade extruded board self-extinguishes within three seconds belongs to the B1 grade extruded board and the B2 grade extruded board burns slowly. This is a relatively vague concept. The effect can only be seen by comparing with ordinary boards. The B2 grade extruded board obviously has a slow burning speed.
