What is PES plastic and is it safe?

I have been trying to find some good research on PES (polyethersulfone) plastic and it’s safety, but have not had much success. It’s relatively new, but everything I have read thus far has been positive.

The Soft Landing interviewed Kevin Brodwick of ThinkBaby regarding PES plastic, which is what ThinkBaby uses for their baby bottles. Read the interview here.

  1. I’m glad you found the article on PES helpful! It has been tough for us to find detailed info on PES too, so we were happy to be able to interview Kevin Brodwick.

    You have a really great blog here! Thanks for highlighting our article.

    Warmest,

      I am planning to buy a baby bottle but I’m not sure which one would be better and safe. Is it better to buy the Born-Free Baby plastic bottle or the AVENT Baby plastic bottle ? Both of these bottles do not have any numbers at the bottom of the bottles. Please advise. All suggestions and experiences shared will be greatly appreciated. Thanks.

        By the way, I want to mention that both Avent and Born-Free Baby bottles that I mentioned above have the box marked as BPA-Free. But I know both of them are made with different plastics.
        Please advise which one is better and safe to use. Thanks.

        Born Free is made from Polyamide and Avent is made with PES plastic. Both are currently viewed as safe plastics. I honestly do not think you could go wrong with either. ThinkBaby bottles are also made with PES plastic. If you want to support a truly BPA, PVC, phthalate-free company though and one who is really focused on safety of their products, I’d go with BornFree. Avent was slow to respond, however, they are now responding. They also have said they will stop selling BPA-ladened bottles in the US (however, they will still sell them outside of the US). They and other bottle makers really were forced into this since the largest bottle retailers — Babies R Us, Wal-Mart and Target stopped selling baby products with BPA beginning Jan 1, 2009.

        But again, the current research is saying PA and PES plastics are safe.

    That article was great. Thanks for posting it. I am wondering what the difference between polyethersulfone and polysulfone. I currently purchased a product claiming to have a polysulfone container, but the research I have found on the internet is saying not to use polysulfone. I wish they made it with polyethersulfone if there is a difference between the two. Any insight? Am I totally confused?

    Thanks!
