Air

Our custom formulated polyurethane adhesives also meet strict requirements for High Efficiency Particulate Air (HEPA) filters, including formulations with low-outgassing and those capable of meeting specific requirements of the various certification agencies. Our polyurethane materials can be found in HEPA filters for the nuclear, pharmaceutical, and semiconductor industries.

Performance benefits:

  • Flow-through to thixotropic viscosity characteristics
  • Flame retardancy
  • FDA-compliant raw materials
  • Ultra-low outgassing

Oil & Gas

Our range of polyurethane/modified epoxy adhesives is formulated to possess excellent physical properties, along with high temperature and chemical resistance to gasoline, hydraulic fluids and oils.

Performance benefits:

  • High temperature resistance (400 F)
  • Excellent chemical resistance (fuels, oils, and solvents)
  • Superior adhesion

Pool & Spa

Our polyurethane molded end cap formulations for the pool and spa industry are resistant to chlorine and other common pool/spa chemicals while also withstanding the growth of mold, mildew, and bacteria. These cast polyurethanes can be formulated in a range of colors and durometers to meet the specific pool/spa filter cartridge assembly requirements.

Performance benefits:

  • High tear strength properties
  • Excellent chemical resistance
  • Mold growth resistance

Reverse Osmosis & Ultrafiltration

Our custom-formulated polyurethane adhesives bond well to specialized membranes in separation process filters and can be formulated to fit different assembly scenarios. The polyurethane’s chemical composition has a high degree of hydrolysis resistance and minimal hardness loss in water at elevated temperatures (185 F).

Performance benefits:

  • Custom formulations with raw materials suitable for NSF/FDA applications
  • Excellent adhesion to various membranes and substrates
