High Density polyethylene (Grade: for the insulating and jacketing of Telecommunication Cables) is used in the outer diameter coating.
Duct Rodders will equipped with different size reel according to the length of rod. There are wheels on the reel, which make it convenient for moving.
Light weight, durable, resistance to acid, alkali, aging resistant, corrosion resistant.
High tensile strength and bending properties, which make it to go through narrow pipes easily.
Good temperature adaptability, the product will not soften in hot weather / nor become brittle in cold weather. Its usability will not be affected by temperature.
Outer protect layer are made of high density polyethylene engineering plastic, which has good anti-UV capability.Cover was coated with long-term UV-resistant polyethylene.
Its surface has the advantage of smooth, wear-resistant and long service life.
There are meter marks on the protect layer of duct rodder, which can be used for measuring distance. Marks are printed by professional printing machine, which has the advantage of strong adhesion, clear writing, waterproof, anti-ultraviolet, it can be still clear even after using many times.
There are several kinds of colors for the rod for your chosen.
