What Material is the MeLuna Menstrual Cup made from?
MeLuna is made from an Elastomer called TPE (thermoplastic elastomer).
Elastomer refers to a natural or synthetic polymer that has elastic properties. Natural rubber for example is an elastomer. MeLuna TPE does not contain any Latex.
Thermoplastic refers to the ability of the material to be molded under the application of heat and it retains its new shape when it cools without a change to the original properties of the material. Plasticity is a term that refers to changeability. By the application of heat the MeLuna can change its shape.
TPE exists in many variants and is made with different components depending on application. Medical grade TPE has very little in common with TPE used for yoga mats for example. Our TPE is specifically manufactured for the medical device industry. The production is very closely monitored and only consists of components suitable for medical device applications.
The material is manufactured by Kraiburg GmbH in Germany. It was developed especially for such highly sensitive applications and has passed the mucosal irritation test with flying colors. You may have encountered this material before in items such as pacifiers. The TPE used in MeLuna cups is BfR, FDA, 2002/72/EC and ISO 10993-10 certified.
You can find more info about the raw material through the Kraiburg website here. https://www.kraiburg-tpe.com/us/products/thermolast/thermolast_m
The Oko-Test Organization rated MeLuna as Sehr Gut (Very Good) in comparison with 21 other cups and tampons tested. You can view the full report here.
More importantly though the MeLuna USA version of the cup was put through the FDA clearance process and registered with the FDA in 2014.
This process goes way beyond just material safety and includes ongoing quality control measures and inspections.

Why is the MeLuna not made from silicone like the other menstrual cups ?
Some of the reasons why we prefer the Elastomer over Silicone are based on improved manufacturing practices that are possible with TPE.
Recently independent studies on menstrual cups by a microbial expert in France have shown that cups made from TPE are less likely to harbor harmful bacteria than menstrual cups made from silicone.
Many products that have been made previously out of rubber or silicone, are now made out of TPE.
TPE has a lower incidence of causing an allergic reaction than silicone.
TPE is also a very pliable material that readily conforms to its surroundings for an even more custom feel for the wearer. You may find that over time your TPE cup becomes a bit more oval in shape after adjusting to its wearer’s shape. This is nothing to worry about. The cup will again conform to your shape the next time you wear it. If you ever would like to return the cup to its original completely round shape, simply boil the cup in hot water.
How are MeLuna cups manufactured?
MeLuna is manufactured in Brand, Germany.
The high quality, pure TPE granules are placed in a special molding machine to be melted and are then injected under high pressure into the MeLuna molds. The machinery is dedicated for use in the production of menstrual cups only. No other materials come in contact with it. The finished cups are then removed after cooling and all cups are immediately checked one by one. This means they will be assessed from all sides, it is also verified that no tiny air bubbles exist. If any errors are present, the item is not released for sale.
Is the MeLuna Menstrual Cup Safe?
The process is controlled and monitored using a quality control system that starts with the delivery of the granules from the world market leader and world's largest manufacturer of TPE, Kraiburg GmbH, on through to the final product.
The quality standard is 9001:2000 certified by an independent body to ISO and monitored.
MeLuna USA cups are also inspected and documented separately by the MeLuna USA distributor in accordance with FDA Quality Control standards.
