..... Most of the parts are made from food-grade polypropylene (PP) which is Bisphenol-A free and the safest plastic to preserve and protect stored milk... This is for the parts that are in contact with breast milk, and the parts that contact skin.
The parts that are not made from PP are made from silicone (like the valves etc). There are other plastics on these breast pumps - but milk doesnt come into contact with them - like the battery pack, power cable etc.
If you are not sure, or are concerned, please contact me. I am happy to help you, and will find the right breast pump to suit your needs.
