Is the vulcanization chemical used in making tires harmful to your health?

Harmful.

There are antioxidants containing nitrosamines in the tire formula. The high temperature and pressure during vulcanization cause the vulcanization flue gas to contain a large amount of nitrosamines. If the ventilation is not good, it may cause cancer over time. The vulcanization chemical industry Cancer rates are higher.

In the production process of tire reclaimed rubber, a large amount of wastewater containing phenol, ammonia, and phosphorus and waste gas containing sulfur dioxide and hydrogen sulfide will be produced, which not only endangers human health, but also causes plant leaves to wither, reduced food production or even no harvests. ;

In addition, benzene pollutants produced in the production process of tire reclaimed rubber are internationally recognized carcinogens. Its chemical structure is not easily degraded in the natural environment, causing lasting damage to soil, water and the atmosphere. And serious pollution.

Extended information:

Tires usually consist of three parts: outer tire, inner tube and pad. There are also those that do not require inner tubes. The inner layer of the carcass has a rubber layer with good air tightness and requires a special rim. The structure of tires in various countries around the world is developing in the direction of tubeless, radial structure, flat (the ratio of tire section height to width is small) and lightweight.

Tire specifications: Specifications are symbolic data of tire geometric parameters and physical properties. There are three ways to express tire specifications: A. Metric (mm); B. Mixed metric and imperial systems; C. Imperial system; Imperial tire specifications are often represented by a set of numbers. The first number represents the tire section width, and the latter number represents the rim diameter, both in The unit is inches.

The letters or symbols in the middle have special meanings: Tire structure: "R" represents radial tires, "D" and "一" represent bias tires.
