Natural Rubber

Natural rubber is a polymer derived from the milky white sap of the rubber tree, scientifically known as Hevea brasiliensis. The sap, also called latex, is collected by tapping the rubber tree, and is then processed to obtain the rubber. Natural rubber is composed of long chains of molecules called polymers, primarily made up of the organic compound isoprene.

Properties of Natural Rubber

Natural rubber has several key properties that make it useful in various applications:

1. Elasticity: Natural rubber can stretch and return to its original shape, making it ideal for products requiring elasticity, such as rubber bands and tires.
2. Flexibility: It is highly flexible, allowing it to conform to various shapes and withstand bending without breaking.
3. Waterproofing: Natural rubber is impermeable to water, making it suitable for waterproof products like rain boots and seals.
4. Insulating properties: It has good electrical insulating properties, making it valuable for use in electrical insulation and protective gloves.

Uses of Natural Rubber

Natural rubber is used in a wide range of products, including:

• Tires for vehicles
• Rubber bands
• Rain boots
• Conveyor belts
• Gloves
• Adhesives
• Medical equipment
• Sports equipment
