Anti-acid
solutions
The hot-casting polyurethane has a high resistance to acid or basic solutions with a pH between 0 and 14 (with a maximum concentration of 30% by weight of the solution) even on manufactured articles with very high hardness, of the order of 70, 80 Shore D.
Politec successfully uses hot casting polyurethane to replace mechanical parts with a hardness of about 80 SH D built with UHMWPE (very high molecular weight polyethylene, often used as an anti acid solution) on chemical plants that work with hydrofluoric acid up to pH 1 and 60°C temperature.
Hot-casting polyurethane has proven to be much superior in terms of abrasion resistance than UHMWPE.
