What is rubber? Or rather, what is natural rubber?

As you know, natural rubber is called India rubber or caoutchouc. Natural rubber is made of polymers of isoprene organic compounds with minor impurities of other organic compounds. It is formed along with water. Today, countries such as Thailand, Malaysia and Indonesia are the leading countries in the production of rubber in the world. Different forms of polyisoprene are known as natural rubber and elastomers as synthetic rubber.

What are the raw materials of rubber?

The raw materials of rubber are actually materials that can be used to make all kinds of rubber and rubber compounds. In order to have better information about the raw materials of rubber, it is better to have an approach to the background and how the rubber was created.

History of rubber

Christopher Columbus discovered that the Native Americans played with rubber balls, which was the main source of this caoutchouc substance, which the English call rubber. The main place of caoutcho trees is the lands of Latin America, especially Brazil. Caoutcho or elastomer is a substance that has rubber properties and increases in length and width against the force of tension and returns to its original state after the force of tension is stopped. This is not a chemical substance and has a natural origin. Rubber is one of the most important raw materials for rubber. This is because this material has high bounce strength, excellent abrasion resistance, very good adhesion properties, and longitudinal and transverse stretching and thickness properties (elasticity).

How to get natural rubber:

At first, to obtain gum or sap from gum or rubber trees, the bark of the tree is cut into grooves. that this gummy liquid (sap) secretes from these grooves and flows in the groove and collects in small containers that are attached to the tree at the end of the groove. For this reason, they choose small containers to avoid rotting or contamination of the sap.

After collection, these leachates should be filtered and protected by adding ammonia. Then the rubber is separated by adding various acids or salts with a process called coagulation. In this process, the rubber is separated from the liquid in the form of a white paste-like mass and is rolled into a thin sheet and finally dries. It is better to know that raw rubber is a sticky material and does not have much elasticity. And by adding sulfur, the strength and elasticity of rubber increases. This process is called vulcanization. After the process of vulcanization, fillers such as carbon black are added to the rubber to increase its elasticity and strength. And finally, the raw rubber becomes a material with high elasticity.

Uses of rubber:

The largest industrial consumption of natural rubber in production (car, passenger, truck and airplane tires, tubes, special industrial parts, vulcanized parts, rubber parts and anti-wear parts) as well as making shoes, belts and conveyor belts, cloud-shaped artifacts, cable covering and Wires, pipes and rubber devices. Also, this valuable material is used in the refining, chemical, dyeing, artificial leather, thread and fabric coating, rubber bands covering tanks and pipes, impact and sound absorbing tires, making mechanical parts and flat and circular washers and countless industries. is no longer used

The types of rubber raw materials are divided into three general categories, which we will give explanations about in the following.

1- Nitrile Butadiene Rubber – NBR – Nitrile Butadiene Rubber

Nitrile rubber or NBR, which is also known as acrylonitrile butadiene rubber, is a type of rubber combination of acrylonitrile and butadiene. It is also known by the brand names: Perbunan, Nipol, Krynac and Europrene.

Properties and applications of NBR rubber

Acrylonitrile butadiene or NBR has generally been proposed as a useful and reliable material in the production of rubber parts for automobiles and other industries. By choosing a rubber (butadiene) with the right amount of acrylonitrile, you can create a rubber that can be used in a wide range of applications such as Areas need to be resistant to oil, fuel and chemicals. When NBR rubber is combined with reinforcing fillers, the vulcanized mixture will have excellent properties, and the optimal tensile strength of more than 25 Mpa is obtained at a hardness of 70-80 Shore A. In general, NBR rubber can be in the spectrum A wide range of hardness in the range of 20 Shore A to be formulated from ebonite. Also, the mechanical properties of the vulcanized mixtures of this elastomer depend significantly on the vulcanization temperature. With a suitable formulation and optimal vulcanization conditions, a mixture with very low compressive strength can be provided. The elastic properties of the unsoftened vulcanized mixture depend significantly on the type of NBR.

2- Styrene Butadiene Rubber – SBR – Styrene Butadiene Rubber

Styrene Butadiene Rubber or SBR, also known as Butadiene Styrene Resin or Buna S, is a type of rubber combination of styrene and butadiene. Other brand names: Ameripol Synpol, Europrene ), Kralex, Polysar, Plioflex, Copo Carbomix, Nipol, Solprene

The main properties of soluble styrene butadiene rubber

Optimal elasticity and tensile strength
Unmatched resistance to abrasion and fatigue
Low resistance to oil, other hydrocarbon liquids and ozone

Uses of styrene butadiene rubber:

• tire manufacturing
  Rubber
  shoe
  Washers
  Coating adhesives
  Sealants
  NR-SBR alloy
  Conveyor and BR-SBR

EPDM – Ethylene propylene diene Monomer

EPDM stands for Ethylene Propylene Diene Monomer. It is a type of compound rubber that has the properties of natural rubber and has a large amount of elasticity and elasticity, so that it can return to its natural state. without any permanent deformation.The main use of ethylene propylene diene monomer or EPDM rubber is to resist acid, gas, salt water, ozone, electricity and heat.
