UL certified FR5 H-class epoxy sheet with High heat resistance used in rail traffic
There are many modules for the use of insulation materials in rail transit, modules of motor and traction motor, module equipment and interior decoration.On safety performance for this kind of civil transport have quite high demand, need fire report, flame retardant grade should be V0, heat resistance grade should be above F, even C grade requirement of heat resistance, besides the material itself needs certain mechanical strength and electrical strength. The commonly used materials in rail traffic are HC-GPO3/HC-FR4/HC-FR5 etc.
Epoxy pultruded tube has high mechanical strength and automatic machining, has high electrical property,excellent Fire Retardant,is widely used as insulating bracket, insulatingspacer, left bracket , right bracket,baseboard,connection rod,lead fixation column in the field of rail transportation.
