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.
