Rubber, plastic, fiber, coating, cotton, wool, silk.

Classification Polymer materials are divided into rubber, fiber, plastic, polymer adhesive, polymer coating and polymer matrix composite material according to their characteristics. Rubber is a class of linear flexible polymers. The secondary valence force between the molecular chains is small, the molecular chains are flexible, and the external force can produce a large deformation, and it can quickly return to its original state after removing the external force.

There are two types: natural rubber and synthetic rubber. Polymer fibers are divided into natural fibers and chemical fibers. The former refers to silk, cotton, linen, wool, etc.

The latter is made of natural polymer or synthetic polymer as raw material, through spinning and post-processing. The fiber has high secondary valence force, small deformation ability and high modulus, and is generally a crystalline polymer. Plastics are made of synthetic resins or chemically modified natural polymers as the main components, and then added fillers, plasticizers and other additives.

Its intermolecular secondary valence force, modulus and deformation are between rubber and fiber. It is usually divided into thermosetting plastics and thermoplastics according to the characteristics of synthetic resins; According to the use, it is divided into general plastics and engineering plastics. Polymer adhesive is an adhesive material made of synthetic natural polymer compounds.

There are two types of adhesives: natural and synthetic. The most widely used are synthetic adhesives. Polymer coatings are made by adding solvents and various additives with polymers as the main film-forming substances.

According to the film-forming substance, it is divided into oil coatings, natural resin coatings and synthetic resin coatings. Polymer matrix composite material is a composite material made by adding various reinforcing materials to polymer compound as matrix. It integrates the performance characteristics of the original material and can be designed according to the need.

Plastic products made of polymer materials.

In addition, polymer materials are divided into ordinary polymer materials and functional polymer materials according to their uses. In addition to the general mechanical properties, insulation properties and thermal properties of polymers, functional polymer materials also have special functions such as conversion, transmission and storage of matter, energy and information. There are polymer information conversion materials, polymer transparent materials, polymer simulated enzymes, biodegradable polymer materials, polymer shape memory materials and medical, pharmaceutical polymer materials.

Processing technology The processing and molding of polymer materials is not a simple physical process, but an important link that determines the final structure and properties of polymer materials. In addition to adhesives and coatings, which can generally be used directly without processing, rubber, fibers, plastics, etc. usually need to be processed into products by corresponding forming methods. The commonly used forming methods for plastic products include extrusion, injection, calendering, blow molding, molding or transfer molding.

Rubber products have molding processes such as plasticizing, mixing, calendering or extrusion. Fibers include spinning solution preparation, fiber forming and winding, post-processing, stretching and heat setting of primary fibers, etc.

During the molding process, the polymer may be affected by changes in temperature, pressure, stress and action time, resulting in polymer degradation, cross-linking and other chemical reactions, resulting in changes in the aggregate state structure and chemical structure of the polymer. Therefore, the processing process not only determines the appearance, shape and quality of polymer material products, but also has an important impact on the supramolecular structure, texture structure and even chain structure of the material.
