advantage:
The main purpose of industrial synthetic rubber materials is to save costs and improve the characteristics of rubber products. Because the price of general natural rubber products is relatively expensive, in order to reduce the cost of enterprises, a large number of low-cost synthetic rubber materials are invested. Synthetic rubber materials also have excellent heat resistance, cold resistance, corrosion resistance and are less affected by environmental factors. Synthetic rubber materials are suitable for normal use between minus 60 degrees and 250 degrees.
shortcoming:
Synthetic rubber also has shortcomings. The main disadvantage is that its tensile effect is relatively poor, and its tear strength and mechanical properties are also relatively poor. However, due to the low cost of synthetic rubber materials compared with natural rubber, it is also a medium and low-grade product produced by many enterprises. of choice.
Physical properties:
Its properties vary from monomer to monomer, and a few varieties have properties similar to natural rubber. Some synthetic rubbers have better temperature resistance, wear resistance, aging resistance, corrosion resistance or oil resistance than natural rubber. It is highly elastic under the conditions of use and has a certain modulus.
Chemical properties:
Synthetic rubber is a variety of polymer compounds that are polymerized by different monomers under the action of initiators. The monomers include butadiene, styrene, acrylonitrile, isobutylene, chloroprene and so on. There are four types of polymerization processes: emulsion polymerization, solution polymerization, suspension polymerization, and bulk polymerization.
