Rubber is an essential natural resource used in many applications, including medical, automotive, and industrial uses. With increased demand for rubber, both natural and synthetic rubbers have been developed. However, there has been an ongoing debate on which rubber is better. In this blog post, we will compare the applications of natural rubber and synthetic rubber in the biotechnology industry.
Natural Rubber
Natural rubber is derived from the sap of rubber trees, primarily grown in Southeast Asia. It is a renewable and sustainable resource that has been used for thousands of years. In biotechnology, natural rubber is used for applications such as:
- Laboratory gloves
- Condoms
- Medical tubing
- Surgical equipment
- Implantable devices
Natural rubber is preferred in the medical field due to its natural flexibility, tensile strength, and biocompatibility. It is also resistant to tear and wear and has better elasticity than synthetic rubber.
Synthetic Rubber
Synthetic rubber is made from petrochemicals such as styrene and butadiene. It was developed during World War II when natural rubber from Asia was in short supply. In biotechnology, synthetic rubber has the following applications:
- Gaskets
- Diaphragms
- Sealing rings
- Artificial valves
Synthetic rubber is preferred for applications that require resistance to heat, chemicals, and UV radiation. It is also less expensive than natural rubber and can be produced in a wide range of colors and hardness levels.
Comparison
There are advantages and disadvantages to both natural and synthetic rubber applications in the biotechnology industry. While natural rubber is preferred for medical devices due to its flexible and biocompatible properties, synthetic rubber is cost-effective and can withstand high temperatures and exposure to chemicals. Here is a comparison of properties for both types of rubber:
| Property | Natural Rubber | Synthetic Rubber |
|---|---|---|
| Source | Natural resource | Petrochemicals |
| Production | Time-consuming | Quick and efficient |
| Biocompatibility | High | Moderate to low |
| Tensile strength | High | Moderate |
| Elasticity | High | Moderate |
| Heat resistance | Low | High |
| Chemical resistance | Moderate | High |
| Cost | High | Low |
As you can see, both natural and synthetic rubbers have their unique set of properties. Manufacturers choose which type of rubber to use based on the specific needs and requirements of the application.
Conclusion
In conclusion, natural rubber and synthetic rubber applications have their respective strengths and weaknesses in the biotechnology industry. Natural rubber is preferred for medical applications due to its biocompatibility and flexibility, while synthetic rubber is used for non-medical applications that require exposure to high temperatures, chemicals, and UV radiation. Manufacturers select which type of rubber to use based on the specific needs of each application.
