Hi Trudy! This is an important question to ask, as microwaving plastic can be a safety concern.
Based on the product specifications for Medline's insulated carafes, including model DYND80556H, these cups are not designed to be microwave safe.
Here's why:
Insulated Construction: The cups are built with a "double-walled" insulation design, which creates a vacuum or air gap between two layers of plastic. Microwaving this type of construction can cause the plastic layers to warp, melt, or even delaminate, destroying the insulation and potentially releasing chemicals.
Material: While the cups are made from BPA-free plastic, the material is not specified as being microwave-safe. Microwaving plastics that are not rated for it can lead to degradation of the material and a risk of chemicals leaching into your beverage.
Manufacturer Recommendations: Medline's product information consistently highlights that these carafes are "top rack dishwasher safe" but does not mention that they are microwave safe. The lack of a microwave-safe designation or symbol is a strong indicator that they should not be used in a microwave.
To be safe and to preserve the integrity of the cup, it is best to heat your beverage in a separate, microwave-safe container and then pour it into your Medline insulated carafe.
Thanks,
