How to use hot melt adhesive in the assembly of filter cartridges? Effective filtering is becoming increasingly important in today’s world. Whether it’s the air at home, drinking water in the city, or fuel in heavy vehicles – filters are required to do more. Hot melt adhesive for filter cartridges is essential in filter assembly.
Air filters in vehicles and buildings are high-performance products. They ensure a continuous supply of fresh and clean air. There are various types of filters, usually composed of different materials. The strong hot melt adhesive used for manufacturing filters not only has the characteristic of wide adhesion to different materials, but also helps to provide high-quality products and efficient manufacturing processes.
How to use hot melt adhesive in the assembly of filter cartridges?
Hot melt adhesive or water-based adhesive is used for air, oil, water, and other applications; HVAC The final stage of filter manufacturing. They laminate multiple layers of media together, improving the efficiency of the filter. The selection of filter adhesive is based on the following criteria:
In the air filter manufacturing industry, there are many applications that use hot melt adhesive for filter cartridges. Hot melt adhesives are resistant to high and low temperatures and provide fast curing time, making them widely used in the manufacture of air filters.
When manufacturing air filters, hot melt adhesive with fast curing time is usually the best choice; Because of the fast running filter machine. Hot melt sealed filter frame, laminated filter media, and carefully close the separator.
EVA Hot melt adhesive; And based on APAO Hot melt adhesives have flexibility at low temperatures and are an ideal choice for this application. These adhesives have excellent bonding strength and processing characteristics.
Polyamide based and polyester based; （PET） Hot melt adhesives are also used for air filters in industrial or automotive ventilation systems that must withstand high temperatures. These hot melt adhesives have high chemical and heat resistance; – And it has stronger adhesion to paper and non-woven fabric. Depending on the application, thermal melting point coating, bead coating, roller coating, or spray coating can be used.
With the development of the plastic industry and the continuous emergence of new requirements in the market, companies that have been using specific granulation systems for a long time need to consider not only cost but also comprehensive understanding of application needs to choose the appropriate granulation system when increasing production capacity. The three main […]
Quick print shops often encounter orders with small quantities, multiple sheets, multiple covers, and tight delivery times. A more practical approach than searching for “universal binding glue” is to establish a process for confirmation, trial assembly, and parameter retention before changing orders. This article explains how to reduce rework from daily order taking scenarios. Core […]
What are the hot melt adhesives for filters? An air filter is a component used to purify the air. Filters are generally used in farms, laboratories, sterile rooms, car engines, car air conditioners, household air conditioners, household air purifiers, etc. 1、 Hot melt adhesive for flat filter The commonly used filter element is a high-efficiency […]
How to use EVA hot melt adhesive? In use, it is often heard that ‘how to use hot melt adhesive?’ or some customers may find that the use of hot melt adhesive is not standardized, which can affect the bonding effect. Today we will explain how to use hot melt adhesive correctly. EVA hot melt […]
