Applications

Polyurethanes and epoxies are used to create components and coatings that protect against corrosion, moisture, and extreme pressures. These assemblies can spend several years underwater, either continuously or intermittently, and the material selected must retain its mechanical and hydrophobic properties.

In production machinery, certain components, including pads, rollers, coatings, covers, liners, and gaskets, must perform under high stress and repeated abuse. Urethane and epoxy formulations are well suited to these applications because of their durability, abrasion and chemical resistance, and superior performance in extreme environments.

Epoxies and polyurethanes are used for potting or encapsulating electronic components, filter media, and even diamonds. They protect the components from dust, moisture, and other environmental factors.

Thermoset polyurethanes and epoxy resins were used as early as the 1950’s for the fabrication of sockets and structural components for artificial arms. The wide range of durometers in our Hapflex™ series make it the product line of choice in the prosthetics and orthotics industry.

Polyurethane and epoxy materials are ideal for low-volume production and often used to create custom components for bikes, cars, and boats that can be decorative or meant to withstand extreme environments.

Polyurethanes and thermosets used in food processing equipment must meet strict requirements and tight tolerances. The resistance to temperature changes is a feature of polyurethanes, making them ideal for use in hot or cold environments.

Polyurethane and epoxy materials are used in the military and defense industries to create gaskets, wheels, casings, and other components. Parts made from polyurethane and epoxy, benefit from increased durability, along with extreme resistance to solvents, heat, abrasion, and chemicals.

Thermoset plastics and rubbers, used in conjunction with Hapco’s color dispersions, can be processed without expensive tooling and equipment, which presents an ideal scenario for professional model maker looking to produce models or replicas in quantities from 1-10,000 units.

Medical devices include a variety of instruments, implants, and equipment used for tasks such as monitoring, diagnostics, and treatment. Many of these devices rely on polyurethane and epoxy formulations to produce durable, ergonomic, and efficient designs.

Urethanes and epoxies are widely employed in filtration and Ultrafiltration manufacturing for sealing, bonding, potting or encapsulating blood, gas, hepa, medical, clean room, wine & beer, pharmaceutical, and biomedical filters.

Tooling and foundry industries significantly use composite tooling materials and elastomeric formulations, specifically Hapflex™ for patterns and core boxes where abrasion resistance is essential, or Hapcast for applications where thermal conductivity is needed.

For over 50 years, engineers and inventors have trusted Hapco’s comprehensive range of moldmaking products, including our polyurethanes, epoxies, and hybrid resins, to replicate production parts, craft molds within a day, and develop prototypes in mere minutes.
