Macromolecular materials, also called polymer materials, are materials composed of macromolecular compounds as the matrix and with other additives (auxiliary agents).Polymer material classification1. Classification by sourcePolymer materials are classified into natural polymer materials and synthetic polymer materials according to their sources.Natural macromolecules are macromolecule substances that exist in animals, plants and organisms, and can be divided into natural fibers, natural resins, natural rubber, animal glues, and so on. Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubber and synthetic fibers, in addition to adhesives, coatings and various functional polymer materials.Synthetic machining uhmw have properties that are not available or superior to natural polymer materials-smaller density, higher mechanics, wear resistance, corrosion resistance, electrical insulation, etc.
2. Classified by applicationPolymer materials are classified into rubber, fiber, plastic, polymer adhesives, polymer coatings and polymer-based composite materials according to their characteristics. 3. Classified by application functionAccording to the classification of material application functions, polymer materials are divided into three categories: general polymer materials, special polymer materials and functional polymer materials. General polymer materials refer to machining uhmw plastic that can be produced on a large scale and have been widely used in major areas of the national economy such as construction, transportation, agriculture, electrical and electronic industries and people’s daily lives.These are divided into different types such as plastics, rubber, fibers, adhesives, and coatings. Special polymer materials are mainly uhmw machining with excellent mechanical strength and heat resistance, such as polycarbonate, polyimide and other materials, which have been widely used in engineering materials. Functional polymer materials refer to polymer compounds that have specific functions and can be used as functional materials, including functional separation membranes, conductive materials, medical polymer materials, liquid crystal polymer materials, etc.
