Pros of Natural Rubber
Natural Rubber offers several key advantages that make it a preferred choice for various applications:
- Exceptional Elasticity: NR provides outstanding flexibility and elasticity, which makes it suitable for products that need to stretch and return to their original shape without damage.
- High Tensile Strength and Durability: With its excellent tensile strength, natural rubber can handle significant mechanical stress, making it ideal for heavy-duty applications.
- Abrasion and Tear Resistance: NR’s resistance to wear and tear makes it highly durable in products that experience high friction, such as tires and industrial belts.
- Good Performance at Low Temperatures: Natural rubber maintains its flexibility and elasticity in cold environments, making it suitable for use in low-temperature applications.
- Biodegradable: Unlike synthetic rubbers, natural rubber is derived from renewable resources and is biodegradable, making it a more environmentally friendly option.
Cons of Natural Rubber
Despite its numerous benefits, there are some limitations to consider when using natural rubber:
- Poor Chemical and Oil Resistance: Natural rubber is not resistant to oils, solvents, or chemicals, limiting its use in applications where exposure to these substances is common.
- Limited Heat and Ozone Resistance: Natural rubber tends to degrade when exposed to high temperatures and ozone, making it less suitable for outdoor or high-temperature environments without added protection.
- Allergy Concerns: Some individuals may be allergic to the proteins in natural rubber, which can be a limitation in medical and consumer products.
- Vulcanization Required: To enhance the durability and elasticity of natural rubber, vulcanization (a chemical process) is required, which adds complexity to its processing.
