What is the chemical composition of the raincoat? Is there really only four carbon fluoride?
A new type of plastic with high temperature resistance, corrosion resistance and good strength, considering the cost, and applicability, generally do not have to do a raincoat. If the improved performance can be considered as a "bone" or performance improver, or a special purpose raincoat"...... This depends on the specific situation. If you only ask the raincoat in life. I can tell you No.
Now the raincoat is usually made of plastic material that we say "plastic"! In chemistry is usually can be made "cloth" "polymer" is the most frequently used "PE" and "PP" etc.. What do you mean by "four CFC" plastics? Chemical name should be "ptfe".
Mainly natural rubber and styrene butadiene rubber has no effect on the human body
