Polyurethane (PU) Casting Glue for Air & HEPA Filters

Achieving a leak-proof end cap seal is vital for cabin air, HEPA, and industrial air filters. We supply professional two-component polyurethane (PU) casting glue designed for consistent foaming and excellent elasticity. This high-integrity adhesive forms a durable, airtight bond with plastic and metal end caps, protecting your filter elements from structural bypass leaks.

Durable Hot Melt Adhesives for Pleat Stabilization

Maintaining uniform pleat spacing is essential for heavy-duty fuel and oil filter elements under high flow. Our industrial hot melt adhesives are pre-engineered to provide fast curing and superior thermal resistance. These adhesives stabilize the filter pleats and prevent collapse, ensuring your filtration systems run smoothly without any dripping or stringing during production.

Seamless Integration with Automated Dispensing Machinery

At Fupei, we streamline your production lines by supplying filter adhesives & sealants that are tested to match our automated gluing machines. Whether you are running high-volume assembly with our PU pouring or hot melt dispensing machinery, these adhesive formulas align with our dispenser flow controls, preventing nozzle clogging and saving material costs.
