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 of Telecommunication cables) is used in the outer diameter coating. Duct rodder will be equipped with different size reel according to the length of rod. There are wheels on the reel,which make it convenient for moving.
Fiberglass duct rodder features 1.Light weight,durable,resistance to acid,alkali,aging resistant,corrosion resistant.2.High tensile strength and bending properties to make it go through narrow pipes easily.3.Good temperatures adaptability, it will not soften in hot weather nor become brittle in cold weather, its usability will not be affected by temperature.4.Its outer protected layer is made of high density ABS resin, which has good anti-UV capability, the advantage of smooth, wear-resistant and long service life.5.There are meter marks on the rod for the user easily read it. The marks is waterproof, ultraviolet and it can be still clear even after using long time.6.The reel is equipped with brake device,the rotating or stopping of the rod can be easily realized just by turning hand.7.It has the tilting type handle, convenient for pushing and pulling.8.It has roller and ring on the top and bottom used for the convenience of duct rodder going through, protect the cover from being scratched.
