The replacement of metal with polymers is gaining momentum. In most cases, the metal is replaced by thermoplastics, the most massive group of polymers. Thermoplastics are easy to process and easy to heat and shape. High-performance thermoplastic processing technologies significantly reduce production costs in comparison with metal processing. In addition, thermoplastics are recyclable, which allows them to be used several times, getting more and more new products.
A striking example of the use of thermoplastics instead of metal is the replacement of pipes for water and gas with plastic ones. The durability of such pipes is up to 50 years, they are not subject to corrosion.
Another plus in favor of using polymers is that gas extraction, from which polymers are obtained, is less destructive to nature than metal extraction.
Thus, the trend for the future is unambiguous: metal will be replaced by polymers more and more often.
