Teflon:
It has high frost and heat resistance. It remains elastic and flexible at temperatures from -70 to + 270 ° C, being the best insulating material of our time. Along with this, Teflon has excellent adhesion and low surface tension, not wetting with grease, water, or other substances and possible solvents. Teflon is absolutely imperceptible and invisible to a person, but its properties have a real effect. Dirt, dust, or water always remains on the surface of the garment, collecting in drops and can be easily cleaned with a brush.
