Plastic hose is an important branch of chemical building materials. The application fields of plastic hose are water supply, drainage, gas, floor heating, electric power communication, agriculture, fire fighting and other fields. According to the different classification of chemical materials, plastic hoses can be divided into PU wire wound hoses, PVC square bone reinforced hoses, EVA/PE bellows, wire and cable protected plastic hoses. According to the Secretary-General of the International Association of Mold and Hardware Plastic Industry Suppliers, China’s plastic hose market economy is more intense and large-scale. More than 2,000 plastic hose and pipe manufacturers have an annual production capacity of over 12 million tons, 300 enterprises with an annual production capacity of over 10,000 tons, and more than 20 enterprises with an annual production capacity of over 150,000 tons. In the field of small-caliber household decoration, the competition is fierce and the threshold is not high, which makes the layout of sales network become the foundation of the development of leading enterprises; in the field of Engineering projects, product production barriers and transport radius restrictions make leading enterprises focus on technology research and development and scale expansion.
