5 common thermal insulation materials
Mineral wool (0.031-0.045 W/mK) offers good insulation and soundproofing but absorbs water. Fiberglass is cost-effective and non-combustible but can irritate lungs. Polystyrene foam (0.030-0.045 W/mK) is great for foundations but sensitive to solvents. Polyurethane foam (as low as 0.020 W/mK) provides excellent insulation and is easy to apply. Cellulose fibers (0.039 W/mK) are good for insulation and soundproofing but need ventilation. For details, contact Imen Polymer Chemie Co.

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.
