Quality control in polyurethane air filters
Air is very crucial thing for combustion in any engine because oxygen present in air helps to burn fuel. A filter needs to filter dirt out of the air, and still allow air to flow into the engine.

What is a form in place foam gasket or FIPFG technology?
Form in place foam gaskets (FIPFG) use polyurethane liquids that cure in air to create seamless, custom gaskets. They offer excellent adhesion, flexibility, and compressibility while minimizing waste. Ideal for automotive and electrical applications, FIPFG seals withstand temperatures from -40 °C to +80 °C and provide UV resistance. The process involves mixing components and allowing the foam to expand and cure for optimal sealing performance.

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.
