Hoses are used in various industries, including agriculture, construction, oil and gas, food, automotive, medical, and more, for fluid transportation. In the hose industry, they are categorized into lines that possess soft properties and flexibility. Therefore, hoses can be divided into two categories: rubber and plastic. Among plastics, flexible PVC granules are considered one of the most important plastics for the production of various hoses due to their high flexibility and suitable environmental resistance.
