significantly, What is the disadvantages of natural rubber?
One of the biggest limitations of natural rubber is its poor resistance to hydrocarbons, fats, oils, and greases. Contact with these substances can cause swelling, softening, or complete dissolution of the rubber part resulting in partial or complete failure.
also What are the disadvantages of silicone rubber?
Some of the key drawbacks to using silicone elastomers can include:
- Cost. Silicone elastomers are a premium product, so they command a higher price when compared to rubber and other materials. …
- Feel. In an untreated form, silicone elastomers can feel slightly sticky to the touch. …
- Compatibility.
What are the downsides of synthetic rubber? Though synthetic rubber has innumerable advantages but it’s disadvantages are no less. ◼It has poor mechanical properties . ◼Its tensile strength is quite weak. ◼Tear strength is also very poor.

What is the advantage of natural rubber?
Both natural rubber and synthetic rubber (IR) have high tear resistance, good low temperature flexibility, and high tensile strength. An advantage natural rubber has over synthetic rubber is that natural rubber has higher tensile strength, higher tear resistance, and low odor compared to IR.
What is the advantage of silicone rubber?
Advantages of silicone rubber
One of the main benefits of silicone rubber is its heat resistance. It offers outstanding high-temperature resistance, with some compounds able to withstand temperatures up to 305 °C. Silicone’s thermal stability means it retains its structure and properties over a wide temperature range.
Is silicone a rubber or plastic?
Technically, silicone could be considered part of the rubber family. But, if you define plastics widely, as we do, silicone is something of a hybrid between a synthetic rubber and a synthetic plastic polymer. Silicone can be used to make malleable rubber-like items, hard resins, and spreadable fluids.
How strong is silicone rubber?
Silicone rubber offers
good resistance to extreme temperatures
, being able to operate normally from −100 to 300 °C (−150 to 570 °F).

Are tires made with real rubber?
Cars were invented in the late 1800s, and pneumatic—or air filled—tires followed not long after. … Today tires consist of about 19 percent natural rubber and 24 percent synthetic rubber, which is a plastic polymer. The rest is made up of metal and other compounds.
Is natural rubber durable?
