Application of polymer material granulator in

Plastics, rubber, fibers, coatings, and adhesives

What is polymer material?

Divided by characteristics into rubber, fiber, plastic, polymer adhesive, polymer coating, and polymer based composite materials;

1. Rubber is a type of linear flexible polymer. Its molecular chain has low intermolecular valence force, good flexibility, and can undergo significant deformation under external forces. After removing external forces, it can quickly return to its original state. There are two types: natural rubber and synthetic rubber;

2. Polymer fibers are divided into natural fibers and chemical fibers. The former refers to silk, cotton, hemp, wool, etc. The latter is made from natural or synthetic polymers through spinning and post-treatment. Fibers have high secondary valence, low deformability, and high modulus, and are generally crystalline polymers;

3. Plastic is mainly composed of synthetic resins or chemically modified natural polymers, with fillers, plasticizers, and other additives added. Its intermolecular sub valence force, modulus, and deformation are between rubber and fiber. Generally classified into thermosetting plastics and thermoplastic plastics based on the characteristics of synthetic resins; Divided into general plastics and engineering plastics according to their purposes;

4. Polymer adhesive is an adhesive material mainly composed of synthetic natural polymer compounds. It is divided into two types: natural and synthetic adhesives. The most commonly used is synthetic adhesives;

5. Polymer coatings are mainly made of polymers as film-forming substances, with the addition of solvents and various additives. According to different film-forming substances, it can be divided into oil-based coatings, natural resin coatings, and synthetic resin coatings;

6. Polymer based composite materials are a type of composite material made by adding various reinforcing materials to polymer compounds as the matrix. It combines the performance characteristics of the original materials and can be fed according to the needs.
