The most common properties of rubber are its elasticity, resistance to water and its use as an electrical insulator. When raw rubber is heated, it becomes sticky, and when it is in colder temperatures, it tends to break, just like the synthetic variety. Rubber is quite stretchy, as indicate...
The difference between natural and synthetic rubber can be seen in the way it is produced, meaning that the properties of each are different. Is one better than the other, though? Well, each one is more suited to certain types of application than the other. Generally, synthetic rubber is ...
Vulcanization was first discovered by Charles Goodyear. ... The rubbers that are not undergone the process of vulcanization are called unvulcanized rubbers. The main difference between vulcanized and unvulcanized rubber is thatvulcanized rubber retracts to its original shape even after applying a large...

Environmental advocacy groups have found that some rubber plantations in Cambodia are destroying forests and livelihoods of local communities.Image: Shutterstock Bouncy, elastic, compressible and moldable—the unique properties of natural rubber make it one of the most widely used materials, found in pro...
1. Definition of Vulcanization: - Vulcanization is a chemical process that involves the addition of sulfur to natural rubber. This process creates cross-links between the rubber molecules, which significantly alters the properties of the rubber. 2. Purpose of Vulcanization: - The primary purpose of...
The basic structure of silicone is made up of polyorganosiloxanes, where silicon atoms are linked to oxygen to create the «siloxane» bond.
