You should choose rubber based on how you will use it, considering the various properties of a rubber. There are many kinds, and each has special features. Some rubbers are strong, bend easily, or resist chemicals and heat. Price is important too. Most rubber comes from synthetic sources, which is about 60%. Natural rubber makes up the other 40%. Here is a quick guide to how rubbers are used in industry:
Rubber Type | Industrial Applications |
|---|---|
Natural Rubber (NR) | Car tires, belts, glue, shoes, medical gloves |
Styrene-Butadiene Rubber (SBR) | Car tires, hoses, belts, gaskets, shoe bottoms |
Nitrile Rubber (NBR) | Car fuel hoses, oil seals, gaskets, gloves, machines |
EPDM Rubber | Roofs, car weather seals, electric insulation, water seals |
Silicone Rubber | Medical tools, food uses, car seals, electric insulation |
Neoprene Rubber (CR) | Wetsuits, hoses, car gaskets, protective coatings |

Think about what matters most before you compare rubber types, especially the properties of a rubber that will best suit your needs.
Key Takeaways
Pick rubber by looking at its features and what you need. Think about how bendy, tough, and safe it is with chemicals.
Natural rubber works well if you need it to stretch and be strong. Synthetic rubber is better for tough places and when you need it to handle chemicals.
EPDM rubber is best for outside because it handles weather well. It also stays flexible when it gets very hot or cold.
Always look for safety labels when you pick rubber for food or medical use. This helps make sure it is safe and follows health rules.
Think about how much each kind of rubber costs. Some types cost more because they have special features. These can help them work better for certain jobs.
Quick Comparison of Properties of a Rubber
Natural vs. Synthetic Rubber
Natural rubber and synthetic rubber are not the same. Natural rubber bends very well and is strong. It stretches a lot and returns to its shape. Synthetic rubber can be made for many uses. It often stands up to chemicals, heat, and weather better than natural rubber.
Here is a simple chart showing the main properties of a rubber:
Aspect | Natural Rubber | Synthetic Rubber |
|---|---|---|
Durability | Good, but gets old fast | High, does not age or weather easily |
Flexibility | Very good | Good, but not as much as natural rubber |
Chemical Resistance | Okay | Very good (depends on type) |
Temperature Tolerance | -20°C to 80°C | -40°C to 230°C (depends on type) |
Cost | Lower | Higher |
Tensile Strength (N/mm²) | 25 | 8 to 30 |
Elongation (%) | 800 | 150 to 800 |
Environmental Impact | Biodegradable | Not biodegradable |
Tip: Pick natural rubber if you want lots of stretch and strength. Choose synthetic rubber if you need it to stand up to chemicals, heat, or weather.
Key Performance Factors
Think about the properties of a rubber that matter most for your job. Here are the main things to look at:
Temperature Resistance: The rubber must work in hot and cold places.
Chemical Compatibility: See if the rubber will touch oil, fuel, or strong chemicals.
Mechanical Stress: Know how much the rubber will stretch, bend, or get pressed.
Environmental Conditions: Check if the rubber will be in sun, ozone, or wet places.
Cost: Make sure the price fits what you need.
Synthetic rubber is great for tough jobs or harsh places. It can be made to fight chemicals, heat, and weather. Natural rubber stretches and is strong but does not last as long in hard conditions.
Different Types of Rubber
Natural Rubber (NR)
Natural rubber is used in many things you see every day. Most natural rubber comes from the Amazonian rubber tree. This tree grows best in warm, tropical places. Asia makes almost all the world’s natural rubber. Thailand, Indonesia, and Vietnam make most of it. In 2022, people made over 15 million tonnes of natural rubber.
Natural rubber is very tough and strong. It does not tear or wear out easily. It stretches a lot and goes back to its shape. It is good for the environment because it breaks down naturally.
Strengths | Weaknesses |
|---|---|
High resilience | Gets damaged by ozone and sunlight |
Good tear strength | Does not work well with oil |
Excellent tensile strength | Needs special steps to make |
