Polyset

United States

Polyset manufactures a variety of polyurethane casting and potting materials for filter end caps in the pool and spa industry. These polyurethane compounds are resistant to chlorine and other common poolspa chemicals while also withstanding the growth of mold, mildew and bacteria. Our polyurethane materials can be formulated in a range of different colors and hardnesses to meet your specific poolspa filter cartridge needs.

Polyset is a leader in the design and manufacture of expansion joint systems for the bridge construction industry. Expansion joints are imperative to the life-cycle of a bridge; the consequence of failing joints as a result of poor quality or improper installation will severely compromise a bridge’s structural integrity. Our Ply-Krete® joint systems are designed to allow for continuous traffic while accommodating movement, shrinkage and temperature variations on both the concrete and steel structure elements of a bridge. Ply-Krete® joint systems consist of a high strength, moisture insensitive, elastomeric concrete nosing material and Ply-Seal®, a waterproof joint seal. This is one of the best systems available in the market for bridges. The “toughness factor” of the Ply-Krete® joint system is second to none. These systems are designed to preserve and protect concrete decks and substructures by preventing water absorption and minimizing chloride intrusion in the most abusive environments.

The reverse osmosisultra filtration markets require adhesives that bond well to specialized membranes in separation process filters. In addition, filter manufacturers can widely vary in their production processes so the adhesive must also be formulated to fit different assembly scenarios. Polyset custom formulates polyurethane adhesives that adhere to both of these requirements. The chemical composition of these materials have a high degree of hydrolysis resistance and very little hardness loss in water at elevated temperatures (85˚C). These adhesives are also formulated with raw materials that will pass FDA and NSF requirements.

Filtration systems are extensively used in today’s oil and gas industry for separation, extraction, purification and treatment. The efficiency of these processes is of course dependent on the performance of the filters. Polyset manufactures a range of polyurethanemodified epoxy adhesives specifically for the oil and gas filtration market. These materials are formulated to possess excellent physical properties and chemical resistance to gasoline, hydraulic fluids and oils. These systems produce a tough, highly impact-resistant material with elevated temperature resistance (250-300ºF).
