How is rubber made

Where are Rubber Chemical Used? Why Rubber Chemicals? How is rubber made? The raw materials to make rubber can be natural or synthetic. Natural Rubber Natural rubber is made from liquid tree sap, latex, that comes from a variety of trees and plants.

Rubber is found in the stems and in the roots of guayule, and it is found in the individual cells of the plant, instead of in latex vessels or tubes.

The rubber content of guayule increases over a period of several years. Rubber from this plant is studied for biomedical applications, because it does not cause allergies.

In order to extract the rubber from the plant, guayule tissue must be thoroughly softened and smashed up to free the rubber particles contained in the individual cells. The quality of rubber from guayule is not good enough for all uses, because it has more impurities than does rubber from Hevea brasiliensis. The other good option for rubber, Russian or Kazak dandelion Taraxacum koksaghyz , is a fast-growing plant with a high-quality rubber that was discovered in in Kazakhstan Figure 3D.

Kazak dandelion grows very close to the ground, can be grown in regions with mild temperatures, and produces yellow flower heads they look like a flower but they are a dense group of small flowers without stem. Kazak dandelion contains rubber in the leaves, flowers, and roots, but only rubber in the roots is good for extraction, due to its higher quality and quantity. For rubber extraction , Russian dandelions must be either pressed or mixed [ 5 ].

Kazak dandelions have another advantage—they also produce a carbohydrate called inulin, which is a substance that can be used in foods as well as the production of medicines against cancer, biofuels, or even bioplastics plastics made out of natural products.

At this point, it is still too expensive to extract the rubber from Kazak dandelions. Through research, a plant with bigger root and higher rubber content can hopefully be developed.

Even though the rubber tree is the best source of rubber available today, it is facing some important threats. Rubber is only produced from plants that grown in certain unique areas. In order to expand the sources of natural rubber and avoid the dangers of limited production, we should search for new rubber-containing plants and improve the ones already known, to try to make them economically competitive.

In some plants it also contains rubber. It is economically very important because the latex collected from the tree is the primary source of natural rubber. A collecting groove is made in the bark of the tree before sunrise and the latex is collected in the late afternoon.

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Establishment of new crops for the production of natural rubber. Trends Biotechnol. Share on Facebook. Core Concept Published: July 19, Every element in a construction project must be tough enough to be safe and suitable for its application.

Whether it is for product Rubber manufacturers enlist the services of rubber testing laboratories like ACE for a number of reasons. In the case of rubber testing for consumer goods, manufacturers and other industry professionals need to know that their product will be safe and effective for How Rubber is Made. The Process of Making Rubber Making rubber is a multi-step process that begins with a rubber tree or petrochemicals, and ends with a wide range of end products.

Types of Rubber The process of making rubber depends on the type of rubber you are talking about. How Natural Rubber is Made When tappers peel back the bark of a rubber tree, they disrupt the plant ducts.

How is Latex Processed into Natural Rubber? What is Synthetic Rubber? Natural Rubber versus Synthetic Rubber Properties Synthetic rubbers are available in many forms, thanks to the wide range of applications from the industrial market. Natural Rubber Properties Natural rubber is resistant to wear from chipping and tearing thanks to its high tensile strength.

Synthetic Rubber Synthetic rubber is more resistant to abrasion than natural rubber. What is Silicone Rubber? In the news. Types of Rubber Testing for Construction In the construction industry, almost every product and material used will have to undergo tension, compression, and cold testing. Rubber Testing for Consumer Goods Rubber manufacturers enlist the services of rubber testing laboratories like ACE for a number of reasons.

Search for:. These trees are native to South America but are today commonly found in Southeast Asia. Latex is gathered from the trees by making a cut in the bark and collecting the runny sap in cups. This process is called tapping.

In order to prevent the sap from solidifying, ammonia is added. Acid is then added to the mix to extract the rubber, in a process called coagulation. This can take about 12 hours. The mixture is then passed through rollers to remove excess water. Once this is complete, the layers of rubber are hung over racks in smokehouses or left to air dry. Several days later, they will then be folded into bales ready for processing.

It was when natural rubber sources became scarce during World War I that German scientists developed artificial rubber. Although these early forms of rubber were inferior in quality to natural rubber, as research developed, synthetic rubber improved.
