1. High polymer materials, also known as polymer materials, are composed of high molecular compounds as the matrix, supplemented with other additives.
2. Synthetic high molecular weight abrasive materials possess properties not found or more superior to those of natural high molecular weight materials, such as lower density, higher mechanical strength, abrasion resistance, corrosion resistance, and electrical insulation.
3. High polymer materials are categorized into natural and synthetic high polymers. Natural high polymers are high molecular substances found in animals, plants, and organisms, which can be divided into natural fibers, natural resins, natural rubber, animal glue, etc.; synthetic high polymer materials mainly refer to the three major synthetic materials: plastics, synthetic rubber, and synthetic fibers. Additionally, they also include adhesives, coatings, and various functional high polymer materials.
