HEPA and ULPA Two-Component Adhesives – Efficient, Durable & Tear-Resistant

Sealing is crucial for HEPA and ULPA filtration systems as well as HVAC systems. PLM Filter's two-component adhesive can operate in various harsh environments, specifically designed for sealing and bonding HEPA and ULPA air filters and HVAC filter frames. This adhesive requires no preheating, possesses excellent flowability and adhesion, and its strength is sufficient to remain intact under rough handling without cracking or tearing.

The filter market is complex and ever-changing, and adhesive suppliers must understand the manufacturing processes and market challenges, and adjust materials and processes as filtration technology evolves. Our adhesives are always at the forefront, providing innovative solutions to address bonding issues. Over the years, we have accumulated extensive experience in the field of sealing and bonding technology, offering a variety of effective solutions to our customers. We are well aware of our responsibilities and are committed to becoming a leading supplier, partner, and resource in the filter industry.

Professional Advice

In the field of two-component polyurethane adhesives, different working temperatures, the chemical properties of the filtration media, and different working environments can all influence the choice of two-component polyurethane adhesives. To help you select the most suitable product, we will make recommendations based on your specific application and provide comprehensive technical support throughout the process.

Firstly, we know that HEPA and ULPA filtration systems may operate at different temperatures, so the adhesive needs to have different high-temperature and low-temperature resistance properties. We will recommend products based on the working temperature of your product.
Secondly, the media filtered by HEPA and ULPA filter systems have different chemical properties. Cleaner filter media and those containing detergents and solvents have distinctly different requirements for the chemical stability of adhesives. We will recommend suitable products based on the media you are filtering.
Additionally, during the HEPA and ULPA filter production process, we will provide you with comprehensive technical support, including adhesive application methods, mixing ratios, and adjustments to the glue spraying machine, helping you improve production efficiency and reduce production costs.

We are committed to providing you with the most professional service and the highest quality products, and we look forward to cooperating with you. If you have any questions or needs, please feel free to contact us.
