Food mashers, sugar and chocolate molds, dough rollers, pill chutes, filling nozzles, and sorting channels are a few examples of components that can be made from Hapco materials. The ease of processing and high strength of polyurethanes makes them the material of choice for these types of applications. Unlike thermoplastics, thermosets are available in small quantities, i.e., quart and gallon units, and can be processed without the use of expensive equipment or tooling. In food and drug applications, where certain components are only manufactured in limited quantities, Liquid Molding is always preferred over Injection Molding.
In the past, manufacturing companies have had reservations using thermosets for food and drug applications. Many thermoset polyurethanes contain mercury and other toxic chemicals that would not pass most biocompatibility requirements. Hapco has solved this issue with the introduction of the Steralloy™ Series.
Steralloy™ products range in hardness from 25A to 84D, making them useful for a wide variety of Food & Drug applications. They have often used in applications that require passing cytoxicity, biocompatibility, or USP Class VI testing, for example.
