Problems solved by technology

With the rapid development of various industries in our country and the improvement of people's living standards, people have put forward higher requirements for the performance of polypropylene pipes. The existing polypropylene materials have flame retardancy and The heat resistance is not very ideal, which limits its application in some special fields. In order to overcome these shortcomings, it is often necessary to modify the polypropylene material used in the power cable protection tube by physical or chemical methods.
