Duct rodder are composed of fiber glass rod which is extruded by fiber glass and high strength resin at high temperature. This type of rod has high tensile strength and flexibility. It was covered by a high density polyethylene engineering plastic as its protect layer,which make duct rodder cover sliding on surface,durable,corrosion resistant and has good insulation performance,which make them safe for using in cable occupied duct. High Density polyethylene(grade: for insulating and jacketing
