Disadvantages of synthetic rubber
Explanation:
A synthetic rubber is an artificial elastomer made from polymerization of various monomers and an alternative for natural rubber. Although the synthetic rubber can be recycled and has some advantages over natural rubber, there are also some disadvantages like:
- The mechanical properties are not that strong compared to natural rubber
- The tearing resistance is lesser than natural rubber especially when hot
- Tensile strength is lesser than natural rubber
- Lesser overall dynamic performance
- Damping level is high
- During flexing, there is more heat built-up
