Solutions for air, oil & gas, pool & spa, reverse-osmosis and ultrafiltration
For 40 years, Polyset has been a leading custom formulator of two-component Polyurethane Adhesive, Elastomer, and Foam Systems for the industrial and commercial industries. We pride ourselves on our in-depth understanding of specific filter processing and performance requirements, batch-to-batch consistency, competitive pricing, and customer service. Our polyurethane materials are available in soft-to-rigid durometers, low-viscosity-to-thixotropic consistencies, with formulated systems available for high-temperature resistance, high-tear strength, and with excellent adhesion to a variety of substrates and filter media.
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.
- 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.
- 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.
- 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).
- Custom formulations with raw materials suitable for NSF/FDA applications
- Excellent adhesion to various membranes and substrates
