Manufacturing stages of anti-wear polyurethane parts and rubber in Isfahan, Iran
Industrial polyurethane rubber is formed and made from the reaction of two chemicals called polyol and diisocyanate. This reaction is carried out in the presence of a catalyst and its product is an elastomeric polymer known as polyurethane rubber. Production of anti-wear and anti-electric polyurethane rubber
The manufacturing and production stages of polyurethane rubber in Iran are as follows:
Preparation of raw materials
The first stage of making polyurethane rubber is the preparation of raw materials. The raw materials needed to produce polyurethane rubber are:
Polyol: Polyol is an organic polymer formed by the reaction of glycols with diisocyanates. There are various types of polyols, each of which has different physical and mechanical properties.
Diisocyanate: Diisocyanate is an organic polymer made of two isocyanate groups. Diisocyanates also have different types, each of which has 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 raw materials
After preparing the raw materials, the ingredients should be mixed together in the correct proportions. The ratio of polyol to diisocyanate is usually 1:2. The catalyst should also be added in a small amount to the mixing container.
Casting or extrusion
The mixture of polyol, diisocyanate and catalyst is then transferred to the mold or extrusion machine. In molding, the mixture is poured into the mold and after hardening, it is removed from the mold. In extrusion, the mixture is forced through a nozzle into the desired shape. Production of anti-wear and anti-electric polyurethane rubber
Cooking
After casting or extrusion, polyurethane rubber must be cured at high temperature to give it physical and mechanical properties. The curing time and temperature are different depending on the type of polyurethane rubber.
Cut and finish
After the curing stage, the polyurethane rubber should be cut into desired sizes and shapes. And it may be necessary to polish the surface of the rubber.
The stages of production and manufacturing of polyurethane rubber are generally done in two ways:
Casting
In the casting method, the mixture of polyol, diisocyanate and catalyst is poured into a special mold and after hardening, it is removed from the mold. This method is suitable for the production and manufacture of rubber parts with complex, precise and calculated shapes.
Production of anti-wear and anti-electric polyurethane rubber.
extrusion
In the extrusion method, the mixture of polyol, diisocyanate and catalyst is transformed into the desired shape through a nozzle. This method is suitable for producing rubber parts with simple and uniform shapes
Polyurethane rubber has a wide range of applications in various industries. This rubber can be used in the production of car parts, furniture, flooring, medical and sports equipment and other products.

History of polyurethane
Polyurethanes were discovered for the first time by Otto Bayer in Germany in 1937, and after that, these materials, having special properties, made great progress in all kinds of industries in the world. Polyurethane anti-wear rubber production in Isfahan, Iran, was the first polyurethane produced by reaction. Alitans are compounds that have a urethane bond in their structure. Polyurethane (PU) is the general name of polymers that have urethane bonds. Production of polyurethane anti-wear and anti-electricity rubber. Production of anti-wear and anti-electric polyurethane rubber
The urethane bond is formed through the addition reaction between an isocyanate group and a compound with active hydrogen such as a hydroxyl group. Isocyanate groups are highly reactive, and for this reason, the progress of their reaction does not require an increase in temperature. Production of polyurethane parts in Isfahan, Iran
(The reaction takes place at ambient temperature) The most important feature of this group of polymers is that a stable structure is created after the reaction. In short, polyurethane can be produced in different forms such as: foam products, films, elastomers, powders, liquids and emulsions. Compounds that have an isocyanate group are:
2.4 or 2.6 toluene diisocyanate
4.4 or 2.4 diphenylmethane diisocyanate
1.6 hexamethylene diisocyanate
In addition to the mentioned cases, there are other isocyanate compounds for the production of anti-wear and anti-electric polyurethane rubber. Compounds that have two or more hydroxyl groups (OH) are called polyols, and the following types are usually used:
Polyether polyol
Polyester polyal
Polycarbonate Polyol
Polycaprolactone Polyl
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. For this reason, when it comes to polyurethanes, it can be said that there are countless types of them. Contact us for the production of anti-wear and anti-electric polyurethane rubber in Iran.

Production of anti-wear and anti-electric polyurethane rubber
This very useful and important material is the result of the genius of Professor Otto Bayer (1902-1982), who is known as the “father” of the polyurethane and rubber industry. The main origins of polyurethane date back to the beginning of World War II, when it was first recognized as a rubber substitute.
During World War II, many different types of polyurethane coatings were used to make clothes that are very resistant to mustard gas, to paint airplanes with a very high gloss, and coatings that are very resistant to corrosion and chemicals, and to protect metal, wood, and Masonry has been used a lot.
By the end of the war, polyurethane coatings would be produced on an industrial scale and would be widely used and could be custom made and distributed for very specific applications. By the mid-1950s, other polyurethanes would be found in a wide variety of coatings and adhesives, elastomers, and very rigid foams.
By the late 1950s, very comfortable cushioned flexible floors became commercially available. By developing cheap polyethylenes, flexible foams opened doors to the upholstery industry and automotive applications. Production of anti-wear and anti-electric polyurethane rubber in Iran.
