Rubber Material Properties
Elasticity & Flexibility
It is important to know how rubber stretches and bends. Natural rubber can stretch a lot before it breaks. It can stretch up to 1000% of its length. Its modulus of elasticity is between 1 and 5 MPa. Its breaking strength is from 16.7 to 28.4 MPa. Synthetic rubber, like SBR, can be strong when reinforced. Specialty rubbers, such as EPDM and silicone, have different stretch and strength levels.
Type of Rubber | Modulus of Elasticity (MPa) | Stretchability (%) | Breaking Strength (MPa) |
|---|---|---|---|
Natural Rubber (NR) | 1 to 5 | 1000 | 16.7 to 28.4 |
Synthetic Rubber (SBR) | ~2 (without reinforcement) | N/A | 17 to 24 (with reinforcement) |
Natural rubber bends many times before wearing out. Specialty rubbers can be made for special bending needs.
Chemical Resistance
Rubber can resist chemicals, which is important for many jobs. Natural rubber does not work well with oils and some solvents. It does resist abrasion and bounces back well. Synthetic rubber, like nitrile, is good at resisting acids, bases, and oils. Specialty rubbers like Kalrez can handle oils, acids, and high heat. This makes them good for tough places.
Nitrile rubber stands up to acids and bases, but not strong oxidizing acids.
Specialty rubbers stay strong when facing harsh chemicals.
Synthetic rubber resists chemicals better than natural rubber.
Durability & Aging
You want rubber that lasts a long time. Natural rubber gets old faster from heat, light, oxygen, and ozone. It gets harder as it ages. Synthetic rubber does not age as fast and works well outside and in factories.
Type of Rubber | Characteristics | Durability Factors |
|---|---|---|
Natural Rubber | Stretches well, strong, and resists wear | Gets worse from heat, light, oxygen, and ozone; hardens over time |
Synthetic Rubber | Can be made to resist chemicals, heat, and last longer | Works better in tough places; does not age as quickly |
Sun and ozone can crack natural rubber and make it brittle. Synthetic and specialty rubbers do not crack as easily.
Thermal Stability
Rubber can handle different temperatures. Natural rubber works from -40°F to 175°F. Synthetic and specialty rubbers, like silicone and EPDM, can handle much hotter and colder temperatures.
Rubber Type | Maximum Intermittent (°F) | Maximum Continuous (°F) | Minimum Degree (°F) |
|---|---|---|---|
Silicone Rubber | 600 | 410 | -75 |
EPDM Rubber | 350 | 250 | -60 |
Neoprene Rubber | 305 | 210 | -40 |
Natural Rubber | 195 | 175 | -40 |
Specialty rubbers like silicone and fluorocarbon work well in very hot or cold places. They are used in cars, planes, and machines.
Other Key Properties
Rubber can resist wear, insulate electricity, and block water. Natural rubber does not tear easily and works well where things rub together. Synthetic rubber keeps its strength in tough conditions and resists chemicals. Specialty rubbers have special features, like stopping flames and insulating better.
Natural rubber keeps electricity from passing through and blocks water.
Synthetic rubber is better at resisting chemicals and heat.
Specialty rubbers work best in hard industrial jobs.
It is smart to check rubber properties before picking the type you need.
Types of Rubber Materials
Natural Rubber
Natural rubber comes from the latex of rubber trees. Workers collect the white liquid by tapping the trees. Factories turn this latex into solid rubber by drying and coagulating it. This keeps the rubber close to its natural state. Natural rubber is very stretchy and bounces back easily. You can pull it far, and it returns to its shape. People use natural rubber in tires, gloves, and balloons. It is also good for shock mounts and stopping vibrations. Natural rubber is used where strong tearing and abrasion resistance is needed. One big plus is that natural rubber breaks down over time. This makes it better for the environment.
Synthetic Rubber
Synthetic rubber is made using chemicals in factories. Polymerization is the process used to create it. This lets people change the rubber for different uses. Synthetic rubber can have special features, like resisting oil, heat, or weather. Some types are styrene-butadiene rubber (SBR), nitrile butadiene rubber (NBR), and ethylene propylene diene monomer (EPDM). Each type has its own good points. SBR is great for tires because it resists wear. NBR does not get damaged by oils and chemicals, so it is used in car parts and gloves. EPDM stands up to sunlight and weather, so it is good for seals and roofs. Synthetic rubber gives more options for tough jobs.
Characteristic/Application | Natural Rubber | Synthetic Rubber |
|---|---|---|
Physical Durability | Very good at resisting wear and tearing | Depends; EPDM is strong and lasts long |
Vibration and Sound Dampening | Strong and good for shock mounts | EPDM and butyl rubber also dampen sound |
Resistance to Environmental Factors | Not good in very hot or cold places | Made to resist things like oil and heat |
Specialty Rubbers
Specialty rubbers are made for special uses. They work where regular rubber cannot. These rubbers can handle very hot, strong chemicals, or tough places. Fluorosilicone rubber stays strong in high heat and resists fuels and oils. Polyacrylic rubber works well in hot engines and resists oil. Epichlorohydrin rubber blocks gas and stands up to chemicals. You see specialty rubbers in planes, cars, and fuel systems. These rubbers help in the hardest jobs.
Tip: If you need rubber for a special job, try specialty rubbers. They have features you will not get from natural or synthetic rubber.
