Filters

Hot melt glues are also effectively used in the filter industry, where they play a crucial role in the assembly and sealing of filtering components. Thermoplastic adhesives offer quick application and excellent adhesion, making them ideal for a wide range of applications in the production of various types of filtering systems. Polyamide-based (PA) and Amorphous Polyolefin-based (APAO) hot melt adhesives also provide high-temperature resistance, a primary requirement in several filter system applications for air and liquids.

1) Air Filter Assembly

Hot melt glues are frequently used in the production of air filters for HVAC (heating, ventilation, and air conditioning), automobiles, and industrial equipment. Hot melt adhesives are used to bond and seal the folds of the filtering material, such as non-woven fabric or filter paper. This process ensures that the filter maintains its shape and structural integrity, maximizing efficiency in capturing particles and contaminants.

2) Liquid Filters

In the liquid filter sector, hot melt glues are used to bond filter parts used in residential, commercial, and industrial contexts. They can be used to secure the support structure to the filtering material, ensuring that all components remain in place even under pressure. This type of application is common in filters for water, oil, and other fluids.

3) Sealing Bag and Cartridge Filters

Hot melt glues are ideal for sealing the edges of bag and cartridge filters where an airtight seal is necessary to prevent bypass of unfiltered air or liquids. This type of sealing is vital to ensure the effectiveness of the filter in applications requiring high purification levels.

4) Specialized Applications

Additionally, hot melt glues are used in specialized applications such as HEPA (High Efficiency Particulate Air) filters used in environments requiring very high levels of air cleanliness, such as hospitals and laboratories. The glue can be used to build and reinforce the filter structure, improving the durability and performance of the filtering system.

In all these applications, the use of hot melt glues not only improves filter effectiveness but also helps reduce production costs and assembly times. Their ability to quickly adhere and form durable bonds on a variety of materials makes hot melt glues an indispensable tool in the filter industry.
