MEDICAL DEVICE DISINFECTION—HOW TO PREVENT CRACKING AND CRAZING Understanding polymer performance is key to minimizing disinfectant-related failures DISINFECTANT-RELATED DAMAGE ON POLYMER HOUSINGS Strong chemicals used to reduce hospital- acquired infections can damage equipment and result in material failures, such as: • Stress cracking • Crazing • Discoloration CHEMICAL RESISTANCE REQUIREMENTS VARY BY ENVIRONMENT • Patient/exam rooms • Operating and radiology rooms • Reception areas • Home (patient equipment & devices) Healthcare devices must perform flawlessly in a myriad of challenging environments and engineers must be certain their devices can withstand increasingly potent disinfectants, which have begun to outstrip the performance of traditional polymers. This procedure was completed by placing one 1/2 inch section of rayon gauze at the apex of each bar, and soaking the gauze with the disinfectant to saturate the material.

As gases may also be delivered into the system by direct injection (then called physical blowing agents), one needs to differentiate between the physical blowing agents (PFAs) and chemical foaming agents (CFAs). The physical blowing agent system requires engineering modifications, such as a high-pressure injection unit, extended screws and barrels, and gas storage or compression units. Once the cavity is filled, the mold opens, or one of the sides has a slide, to allow the expansion of the gas-loaded compound.
