MBT is widely found in all kinds of rubber products. The surfaces of rubber gloves, condoms, medical catheters, automobile tires, swimming caps and goggles, baby simulated nipples, rubber bands and plastic racetracks all contain a lot of MBT.
The main material of 3G stadium (the third generation artificial grass stadium) which is widely promoted in Britain now is also rubber crumbs. The latest report points out that the plastic products in the stadium contain a lot of toxic chemicals such as mercury, lead and arsenic, which pose a great threat to the health of players, especially goalkeepers.

Characteristics of rubber products:
1. When rubber products are molded, they cannot be eliminated due to the cohesion of the elastomer after being pressed under great pressure. When they are molded from the mold, they often have extremely unstable shrinkage, and it takes some time to become gentle and stable.
2. Rubber is a hot-melt thermosetting elastomer, and plastic is a hot-melt cold-set elastomer. Due to the different types of sulfides, the temperature range of rubber vulcanization is very different, and even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time, otherwise there may be differences in product quality.
3. Rubber products are rubber mixtures made by mixing rubber raw materials in an internal mixer. When mixing rubber, design the formula according to the characteristics of the required rubber products and determine the hardness of the required products. This product is molded by rubber flat vulcanizer. After the product is formed, the flash treatment is finally carried out to make the surface of the product smooth and burr-free.
