According to classification by application function, polymer materials are divided into three major categories: general-purpose polymer materials, special polymer materials, and functional polymer materials.
General-purpose polymer materials refer to those that can be produced on a large industrial scale and have been widely used in major national economic fields (such as construction, transportation, agriculture, and the electrical and electronics industry) as well as in people’s daily lives. This category is further divided into different types, including plastics, rubbers, fibers, adhesives, and coatings.
Special polymer materials are mainly a type of polymer materials with excellent mechanical strength and heat resistance, such as polycarbonate and polyimide. They have been widely used as engineering materials.
Functional polymer materials refer to polymeric compounds that have specific functional effects and can be used as functional materials. They include functional separation membranes, conductive materials, medical polymer materials, liquid crystal polymer materials, and more.
