Near atmospheric operation permits corrosion free and scale-resistant polypropylene construction, and also allows the use of low-grade heat to drive the process.
Lack of sufficient research caused enormous reliability problems, especially in regions requiring the use of salt on winter roads, such as sticking and corrosion.
Vehicles and other metallic structures begin to succumb to corrosion that strips away paint and protective coatings, resulting in rust that eats through metal.
