Manufacturing stages of anti-wear polyurethane parts and rubber in Isfahan, Iran
The steps for manufacturing and producing polyurethane rubber in Iran are as follows:
Preparation of raw materials
The first step in making polyurethane rubber is to prepare the raw materials. The raw materials required for the production of rubber are:
Polyol: Polyol is an organic polymer formed by the reaction of glycols with diisocyanates. There are different types of polyols, each with different physical and mechanical properties.
Diisocyanate: Diisocyanate is an organic polymer made from two isocyanate groups. There are also different types of diisocyanates, each with different physical and mechanical properties.
Catalyst: A catalyst is a chemical substance that increases the rate of the reaction step between polyol and diisocyanate.
Mixing the raw materials
After preparing the raw materials, the materials must be mixed in the correct ratio. The ratio of polyol to diisocyanate is usually 1:2. The catalyst must also be added to the mixing container in small amounts.
Casting or extrusion
The mixture of polyol, diisocyanate and catalyst is then transferred to a mold or extrusion machine. In molding, the mixture is poured into a mold and removed from the mold after it hardens. In extrusion, the mixture is fed through a nozzle into the desired shape. Production of anti-wear and anti-static polyurethane rubber
Cooking
After casting or extrusion, rubber must be cured at high temperatures to give it physical and mechanical properties. Curing times and temperatures vary depending on the type of polyurethane.
Cutting and finishing
After the curing stage, the rubber must be cut into desired sizes and shapes. The surface of the rubber may need to be polished.
The production and manufacturing steps of polyurethane rubber are generally carried out in two ways:
Casting
In the casting method, a mixture of polyol, diisocyanate, and catalyst is poured into a special mold and removed from the mold after it hardens. This method is suitable for producing and manufacturing rubber parts with complex, precise, and calculated shapes.
Extrusion
In the extrusion method, a mixture of polyol, diisocyanate, and catalyst is forced through a nozzle into the desired shape. This method is suitable for producing rubber parts with simple and uniform shapes.
Polyurethane rubber has a wide range of applications in various industries. It can be used in the production of automotive parts, furniture, flooring, medical and sports equipment, and other products.

History of polyurethane
Polyurethane rubber was first discovered by Otto Bayer in Germany in 1937. Since then, this material has made significant progress in various industries around the world with its unique properties. The production of polyurethane anti-wear rubber in Isfahan, Iran marked the first production of polyurethane through a reaction process. Polyurethanes are compounds that have urethane bonds in their structure. Polyurethane (PU) is a general term used for polymers that have urethane bonds.
The production of polyurethane anti-wear and anti-electricity rubber has been a significant achievement. The urethane bond is formed through an addition reaction between an isocyanate group and a compound containing active hydrogen, such as a hydroxyl group. Isocyanate groups are very reactive, which allows their reaction to proceed without the need for an increase in temperature. This is why the production of polyurethane parts in Isfahan, Iran is carried out at ambient temperature.
The most important feature of this polymer group is that a stable structure is formed after the reaction. In summary, polyurethane can be produced in various forms including foam, film, elastomer, powder, liquid and emulsion products. Some compounds containing isocyanate groups are:
2.4 or 2.6 toluene diisocyanate
4.4 or 2.4 diphenylmethane diisocyanate
1.6 hexamethylene diisocyanate
In addition, other isocyanate compounds are used in the production of anti-wear and anti-static polyurethane rubber. Compounds containing two or more hydroxyl (OH) groups are called polyols and the following types are commonly used:
Polyether polyol
Polyester polyol
Polycarbonate polyol
Polycaprolactone polyol
In addition, instead of hydroxyl groups, compounds such as carboxylic acids and amines that have active hydrogen can also be used in combination with isocyanates. As a result, there are countless variations of polyurethane available for different applications.
