# What is Cast Polyurethane: Properties and Applications

When a metal part breaks in the middle of a work process or rubber seals fail to last a week, it's time to look for alternatives. Cast polyurethane can be the solution due to its wear resistance and durability. In this article, we will explore what cast polyurethane is and why it is the best choice for many industries.

## What is Cast Polyurethane?
Cast polyurethane is a synthetic elastomer created from isocyanate and polyol, manufactured using the free casting technology. This material is noted for its high wear resistance, which is 10 times greater than that of rubber, and its working temperature range from -60 to +100 °C. Thanks to its unique structure, polyurethane combines the strength of metal and the elasticity of rubber, making it an ideal choice for various industrial applications.

The process of manufacturing polyurethane products using free casting technology involves pouring the polymer into molds, allowing for parts of any shape and size. This enables the production of custom parts that meet your equipment specifications. For example, shafts and shaft linings can be designed for specific diameters and lengths, ensuring precision and reliability in operation.

## Advantages of Polyurethane Products
Polyurethane offers several advantages over traditional materials such as metal or rubber. These include high wear resistance, providing a long service life for parts. The wide operating temperature range from -60 to +100 °C allows polyurethane to be used in various climatic conditions. Its excellent elasticity and strength make polyurethane resistant to impact and abrasive wear.

Additionally, polyurethane has high resistance to chemical influences, enhancing equipment reliability. An important aspect is the reparability of polyurethane products. They are easy to maintain and replace when worn, significantly reducing downtime costs. For example, in the maintenance of screens and sieve parts, polyurethane allows for quick restoration of equipment functionality.

## Comparison of Polyurethane with Other Materials

| Property | Polyurethane | Rubber | Metal |
|----------------------|----------------------------------------|-----------------------|------------------------|
| Wear Resistance | 10 times higher than rubber | Significantly lower | High, but heavier |
| Working Temperature | From -60 to +100 °C | Limited | Wide |
| Reparability | High | Medium | Complex |
| Noise | Low | Medium | High |
| Weight | Light | Light | Heavy |

## Application Industries
Cast polyurethane is widely used in 12 industries, including mining, metallurgy, and food processing. For example, in the mining industry, it is used to manufacture [screens and sieve parts](/katalog), significantly extending equipment life. In mechanical engineering, polyurethane is used to make bushings and rollers, reducing noise and increasing the durability of assemblies.

The printing and food industries also actively use polyurethane for parts that come into contact with aggressive environments or experience intense wear. This ensures stable equipment operation with minimal maintenance costs.

## How Polyurethane Parts are Manufactured and Installed
Manufacturing polyurethane products using free casting technology ensures high quality and precision of parts. After pouring the polymer into molds, the product undergoes a curing process, ensuring its strength and stability. This allows for the production of custom parts that perfectly match your equipment specifications.

Installing polyurethane products usually does not require special tools, but it is important to follow the manufacturer's instructions to ensure longevity. For example, for the proper installation of bucket elevators, it is necessary to check the reliability of fastenings and the absence of mechanical damage on the surface of the parts.

## Maintenance of Polyurethane Products
Maintenance of polyurethane parts involves regular inspection for wear and timely replacement of worn elements. This helps avoid emergency equipment shutdowns and maintains production process efficiency. Thanks to high reparability, polyurethane allows for quick restoration of part functionality, which is crucial for continuous enterprise operation.

> **Engineer’s Tip:** When selecting polyurethane hardness, consider the operating conditions: for abrasive environments, choose products with higher hardness, while for parts subjected to impact loads, medium hardness products are suitable.
