Conveyor belts are among the most important components in almost every industry. You can find them in mining sites, airports, farms, and food industries. They help move things safely and quickly from one place to another. Behind this durability, the main reason is rubber. But not all conveyor belts are made of the same rubber. So the question arises: What types of rubber are used in conveyor belts?<\/span><\/p>\n

 <\/p>\n

Remember, conveyor belts need to handle a variety of materials. For example, they deal with food items, harsh oils, and chemicals. So, for handling this variety of materials, one type of rubber is not enough. That’s why manufacturers choose from some specific rubbers for making conveyor belts. But if you don’t know about those rubber types, worry not! In this guide, I will discuss the main types of rubber used in conveyor belts and their specifications. So let’s get started.<\/span><\/p>\n

 <\/p>\n

Why Is Rubber Used in Conveyor Belts?<\/b><\/h2>\n

\"Why<\/p>\n

You might have seen that almost all conveyor belts are made of rubber. Have you ever wondered why? There are several reasons why rubber is the best option for conveyor belts. First of all, rubber offers the perfect balance of flexibility and durability at the same time. It is soft enough to bend but strong enough to withstand harsh conditions and stress.<\/span><\/p>\n

 <\/p>\n

This durability and flexibility help belts work effectively in all conditions. Secondly, rubbers have natural resistance against chemicals, oil, heat, and stress. As you know, in factory and industry conditions, conveyor belts are constantly exposed to harsh materials. In such situations, normal <\/span>sabuk konveyor kain<\/b><\/a> deteriorate. But it is rubber that resists these problems and maintains its shape and structure.<\/span><\/p>\n

 <\/p>\n

Lastly, rubber also helps protect the conveyor system itself. In many cases, heavy items are dropped onto the belts from a height. Rubber has shock-absorbent abilities. It quickly absorbs the shocks and prevents the entire conveyor system from being damaged. It also helps lower belt repair and maintenance costs because rubber usually lasts longer.<\/span><\/p>\n

 <\/p>\n

Main Types of Rubber Used in Conveyor Belts<\/b><\/h2>\n

 <\/p>\n

As you know, there is no one fixed use of conveyor belts. Every industry uses them as needed. For example, some are used to transport food items, while others are used in handling harsh chemicals. Due to varying usability, the type of rubber used to make conveyors also varies. For better understanding, let’s discuss the main types of rubber used in conveyor belts and their properties.<\/span><\/p>\n

 <\/p>\n

1- Natural Rubber<\/b><\/h3>\n

\"Natural<\/p>\n

The first most common rubber choice for conveyor belts is natural rubber. It comes directly from rubber trees, which excrete a milky liquid called latex. After processing, latex becomes a flexible, strong rubber used in many things, including conveyor belts. What makes this rubber stand out is its excellent abrasion resistance. As you know, <\/span>sabuk konveyor pertambangan<\/b><\/a> often need to handle rough, abrasive materials such as converter cements and more.<\/span><\/p>\n

These materials rub against the belt’s surface, causing damage. But natural rubber can effectively resist abrasion and maintain its structure. Also, natural rubber has higher natural flexibility. This flexibility makes the conveyor move around rollers and pulleys without the risk of cracking. Along with these benefits, NR also has some shortcomings. For example, it does not resist oil, grease, or chemicals very well. If the belt works in oily environments, the rubber may become soft, weak, or swollen over time.<\/span><\/p>\n

 <\/p>\n

2- Styrene Butadiene Rubber\u00a0<\/b><\/h3>\n

The second rubber you will find on the conveyor belts is SBR. It is made by combining chemical materials instead of using natural latex from rubber trees. Generally, natural rubber costs more due to its tough extraction and processing. That’s why manufacturers developed SBR in the lab to lower costs while maintaining the same qualities. For example, it is well known for its good resistance to wear and surface damage. Conveyor belts often carry materials that rub against the belt as they move.<\/span><\/p>\n

Over time, this rubbing can slowly wear down the belt surface. SBR handles this type of wear fairly well, like NR. Another great thing about SBR is its resistance to aging. Generally, regular rubber weakens or cracks when exposed to air or outdoor conditions. But SBR maintains its condition for a reasonable period. Your conveyor belts made with SBR can be easily used in harsh outdoor environments. But remember, SBR conveyor belts are not handy in resisting chemicals and oils. That’s why they are used only in packaging units, light manufacturing plants, and warehouses.<\/span><\/p>\n

 <\/p>\n

3- Nitrile Rubber<\/b><\/h3>\n

Nitrile Rubber, commonly called NBR, is a special type of synthetic rubber used in conveyor belts. In many industries, conveyor belts come into contact with petroleum products, fats, or lubricants. Here, ordinary belts fail as they cannot resist such harsh materials. Still, nitrile rubber is specifically designed to resist this type of damage. That’s why sometimes oil industries call it oil-resistant rubber.<\/span><\/p>\n

In addition to its oil resistance, NBR also withstands wear and surface damage caused by friction. When the harsh, abrasive material rubs against the NBR conveyor belt, it maintains its structural integrity and does not crack. But one limitation of the NBR is its hardness. Unlike natural rubber, it is not as flexible. So the chances of cracks often increase, especially under direct sunlight, ozone, or harsh outdoor weather.<\/span><\/p>\n

 <\/p>\n

4- Neoprene Rubber\u00a0<\/b><\/h3>\n

\"Neoprene<\/p>\n

Neoprene Rubber, also called Chloroprene Rubber (CR), is another synthetic rubber. CR’s main specialty, which makes it a good choice for conveyor belts, is its versatility. This rubber can withstand several working conditions simultaneously. How? Basically, CR is highly strong, flexible, weather-resistant, and oil-resistant. So, when used in outdoor sunlight, rain, and moisture, it does not crack, swell, or deteriorate.<\/span><\/p>\n

Similarly, when it comes to handling oil and chemicals, Neoprene still stands out. Also, sometimes conveyor belts need to operate in conditions with a higher fire risk. There, CR works efficiently due to its flame-resistant properties. It means it does not catch fire easily and can help slow down the spread of flames. Due to all these unique properties, the cost of CR is higher, which can be a disadvantage for small industries.<\/span><\/p>\n

 <\/p>\n

5- EPDM Rubber<\/b><\/h3>\n

EPDM rubber (Ethylene Propylene Diene Monomer) is also used in making several types of conveyor belts. Belts that need to withstand environmental stress are often made of EPDM. Why? The main reason is its chemical structure, which contains diene monomers. These monomers remain stable when exposed to sunlight, oxygen, and ozone in the air. Most people notice that rubber materials slowly “age” when left in the open air for long periods.<\/span><\/p>\n

But EPDM is designed to slow this aging process, so your conveyor can work well outdoors. At the same time, EPDM handles both heat and cold equally well. For example, if you keep it in cold conditions, the belt will not become stiff or crack. Similarly, when carrying hot material, EPDM conveyor belts do not melt easily. But despite all this, EPDM is not meant for oil or chemical resistance. It starts cracking and damaging when exposed to such petroleum-based substances.<\/span><\/p>\n

 <\/p>\n

6- Silicone Rubber<\/b><\/h3>\n

Silicone rubber is a special type of synthetic rubber used to make conveyor belts that require the utmost cleanliness. Actually, silicone naturally has a non-stick nature. It means that no material can stick to its surface, which leads to contamination. This property is essential for industries where hygiene is a major concern. For example, in food processing, baking, and pharmaceutical industries, safety standards are critical.<\/span><\/p>\n

So it is silicone rubber that helps these industries safely handle their products. In addition, silicone rubber is naturally safe for contact with food and medical products. It does not readily react with many substances and does not release harmful materials during use. So, the food industry heavily relies on silicone rubber belts. However, silicone might not fit under heavy industrial stress. It has lower abrasion resistance, so harsh, rough materials can damage its surface.<\/span><\/p>\n

 <\/p>\n

7- Butyl Rubber<\/b><\/h3>\n

In the end, it comes down to butyl rubber, which is a favored choice for making conveyor belts. Some conveyor belts need to provide strong sealing, stability, and protection against air, moisture, and gases. For these responsibilities, IIR proves handy. Actually, this rubber type has very low permeability to air and gases. It means it does not let air, moisture, or gases pass through it easily. This property distinguishes it from other rubber types, where air or moisture can affect their structure.<\/span><\/p>\n

But IIR does not allow air to pass or cause swallowing. Also, in humid places, such conveyor belts perform well because they have no moisture or vapor absorption. Butyl rubber also has the ability to absorb vibration and reduce shock from movement. As a result, conveyor belts maintain stable movement and do not shake, preventing material from dropping. However, IIR is not efficient at handling rough or sharp materials due to its delicate surface.<\/span><\/p>\n

How Manufacturers Choose the Right Rubber for Conveyor Belts?<\/b><\/h2>\n

 <\/p>\n

As you can see, there are various types of rubber suitable for conveyor belts. But the manufacturer does not choose any of them randomly. They study several aspects, such as the job of conveyor belts and the nature of rubber, and then make the selection. Let’s discuss what factors manufacturers consider when choosing the rubber for conveyor belts.<\/span><\/p>\n
