Castable urethane raw materials are liquid, which permits them to be pumped, metered, mixed and dispensed by machines under very precise control of temperature and ingredient proportions. They enter molds as a hot liquid at low pressure and are cured at an elevated temperature. This unique characteristic allows us to mold any shape, any size. We can mold very large urethane parts with thick cross-sections which are completely uniform throughout. Urethane typically offers a longer service life compared to plastics or conventional rubber. Urethane parts can be soft as a sponge, hard as a rock, or anywhere in between. Some urethane formulations are FDA-approved for food contact applications.
