Rubber products refer to various rubber products produced with natural and synthetic rubber as raw materials

Characteristics

1. When rubber products are molded, they are pressed under high pressure. Because the cohesive force of the elastic body cannot be eliminated, they often produce extremely unstable shrinkage when they are molded and released from the mold (the shrinkage rate of rubber varies depending on the type of rubber). It takes a period of time before they can be stabilized. Therefore, when a rubber product is designed, no matter the formula or mold, it is necessary to carefully calculate and match. Otherwise, it is easy to produce unstable product size and low product quality.

2. Rubber is a hot-melt thermosetting elastomer, while plastic is a hot-melt cold-setting elastomer. Due to the different types of sulfides, the temperature range of rubber molding and curing is also quite different, and it can even be affected by climate changes and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted appropriately at any time. If not, the quality of the products may be different.

3. Rubber products are made of rubber raw materials after mixing in a rubber mixer. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by a rubber flat vulcanizer. After the product is formed, the flash is finally processed to make the surface of the product smooth and burr-free.

4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance structure of rubber and products changes during processing, storage and use due to the combined effect of internal and external factors, and then loses its use value. It manifests as cracking, stickiness, hardening, softening, powdering, discoloration, mildew, etc.

The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. It can be seen that the rubber industry has a wide variety of products and a very broad backward industry.
