1. According to the inquiry and purchase network, synthetic rubber is made from petrochemical raw materials such as oil and natural gas by high temperature and high pressure polymerization, while natural rubber is made from natural latex. The price of petrochemical raw materials is generally high, and the process of manufacturing synthetic rubber is complicated. Therefore, compared with natural rubber, the raw material cost of synthetic rubber is higher.

2. Compared with natural rubber, the production process of synthetic rubber is more complicated, and it needs to be polymerized under various conditions such as high temperature, high pressure and catalyst. The production process is difficult, so the production cost is high.
