have elastic properties
because humans cannot make synthetic rubber exactly the same as natural rubber.

Rubber is not an acid it is a natural polymer.
Vulcanized rubber is process that changes the properties of natural rubber so that it is more usable for products. Natural rubber hardens rock-solid in freezing temperature and melts into goo in summer heat. For an interesting reprint of a Readers Digest article on the invention of rubber - see the attach link.
Yes, natural rubber is generally more elastic than synthetic rubber due to its molecular structure, which allows it to stretch and return to its original shape more easily. Synthetic rubbers may have other desirable properties, such as chemical resistance or durability, but they often have less elasticity compared to natural rubber.
Yes, natural rubber can react with strong acids, leading to its degradation. The acidic environment can cause hydrolysis of the polymer chains in rubber, resulting in softening, swelling, and ultimately breaking down the material. It is advisable to avoid exposing natural rubber to strong acids to maintain its integrity and properties.
Rubber is made from the natural sap of the rubber trees, which is known as latex. The latex needs to be processed on heated horizontal rollers. Chemicals are added depending on the properties wanted in the finished product.
The ash content in natural rubber is typically less than 0.1%. Ash content refers to the residue left behind after burning a sample of rubber, which mainly consists of inorganic minerals and fillers. High ash content can reduce the quality of rubber and affect its properties.
Spandex, also known as elastane, is primarily a synthetic fiber made from petroleum-based chemicals. However, there are natural sources of elastomeric materials that can provide elasticity, such as rubber from rubber trees (Hevea brasiliensis). While spandex itself is not derived from a natural source, the concept of elasticity can be found in natural rubber and other natural fibers, though they do not possess the same properties as spandex.
Natural rubber is made from latex which is taken from trees and is widely used in many products to this day. Synthetic rubber is preferable in most applications today due to the fact that it is more durable than natural rubber and the chances of allergic reactions are smaller.
Natural rubber is the main resource used for making tires and erasers. It is derived from the latex of rubber trees and is a key component in the production of these products due to its elastic properties and durability.
Mixing natural rubber with nitrile rubber is possible. In fact, it is quite common to mix natural rubber with other kinds of rubbers.
