Risks and prevention of polybutadiene rubber hazards
Some tips for polybutadiene rubber One of the most important aspects of PBR that is dangerous to human health is that polybutadiene polymeric materials should not be exposed to oxidants at all when they are in their packaging. It should be noted that PBR does not pose a direct risk to the environment. But if it is in pure contact with the skin or eyes of people, the polymer particles cause severe irritation in these areas and cause redness and pain in the eyes or skin. Therefore, to prevent these events, it is better for people who come in contact with this substance to always use masks and special clothes for their work. Contact with flammable sources should also be strictly avoided. This is because if PBR decomposes by heat, it is released into the environment in the form of oxygen, carbon and carbon dioxide, reducing the oxygen in the…
Why natural rubber is rarely used in heavy tires
Why NATURAL rubber is rarely used in heavy tires Heavy tires are purchased mainly for their durability and re-coating capability, which is derived from the natural rubber properties used in them. The re-coating capability in the lightweight tire market is not that important. In the formulation of the compound used in aircraft tires, natural rubber is usually used because of its resistance to the heat generated during landing and take-off of the aircraft. On the other hand, in agricultural tires, because they are often used in soft and muddy soils, the formulation used is programmed based on less heat. Therefore, natural rubber is rarely used in their construction. In the formulation of these tires, mainly oiled synthetic rubber (SBR) is used. For various reasons, polybutadiene synthetic rubber alone is not very important, but its combination with two other types of rubber improves abrasion resistance and prevents high heat in service…
Rubber dandelions
Today’s tires are a combination of synthetic tires and natural tires made from rubber trees. But researchers have succeeded in extracting a substance from the dandelion plant that is used to make tires. Dandelions are practically unused plants except for use in a variety of salads, herbal drinks and some beverages. At least until now. But a Russian species of the plant, called Taraxacum kok-saghyz, or TKS for short, could revolutionize the rubber industry.

But a Russian species of the plant, called Taraxacum kok-saghyz, or TKS for short, could revolutionize the rubber industry. Despite the invention of synthetic tires, like all synthetic materials that absorb natural raw materials, these tires are strong and resilient to natural tires. This is because natural rubber molecules, which are the product of…
