Fast setting time, outstanding bonding strength, and good operability, suitability for fast production, are the properties that belong to hot melt adhesives, which is the best selection for air filter productions. Hot melt adhesives assist filter shaping, and can be applied on filter pleating, filter, assembly, cap fixing and bonding, hollow fiber stuffing, bonding two sides of filtration media.

Oil filter applications include auto engine oil filter, scooter engine oil filter, and auto ignition system filter. Besides the pleating glue and frame assembly glue, cap sealing and filter paper positioning are also the important applications of oil filters. Eco-friendly hot melt adhesives are most suitable grades for these due to good oil resistance and heat resistance.
