Basic pu chemie
Polyurethane and epoxy coatings both protect surfaces, but differ in properties. Polyurethane cures faster, offers flexibility, UV protection, and is ideal for high-traffic areas and marine use. Epoxy is more chemical-resistant, making it suitable for harsh environments. Polyurethane is more elastic, while epoxy is stiffer and more durable against chemicals.

Air filter foam system
Natural rubber was once the main material for sealing devices, but silicones and polyurethanes have replaced it due to their better properties. High-density polyurethane foams are now used in automotive air filters, offering benefits like elasticity, strength, and temperature resistance. These foams contain tiny bubbles formed during production, and their manufacturing involves mixing polyols and isocyanates, with curing taking place at room temperature through an exothermic reaction.
