Rubber Rings Wholesaler Introduce that the preparation of rubber raw materials can be divided into three basic processes:

1. Plasticizing: Plastic training is to cut the raw rubber, plasticize and homogenize the raw rubber, and help the mixing operation of the compounding agent. The effect is to improve the dispersion of medicines, prevent frictional heat during operation, and cause scorching of rubber, which in turn changes the processability of rubber.

2. Kneading: Kneading is to mix the compound medicine into the raw rubber that has been plasticized, and the quality of the kneading directly affects the quality of the product. The drug is unevenly dispersed, the molecular structure cannot be completely cross-linked, and the rubber cannot achieve the desired physical properties.

3. Extrusion: After the raw rubber is mixed, the excess air contained in the rubber is extruded through the extrusion operation, and the required thickness is completed to facilitate the molding operation in the mold.
