Chairman of the Board and Chief Executive Officer at Celanese
Yeah. Look, I would say, we expect auto builds to be flat year-on-year. If you look at the industry and globally. Now, I think that changes region to region. I think Asia is doing a bit better. I think Europe is doing a bit worse. I think the US has been between there. I think that's pretty consistent though with an industry view on auto builds. I think while we all hope that chip shortage was going to improve, I think now every most things you read by knowledgeable people say it's probably the end of next year before that starts to improve.
So our expectation is auto builds will continue to be flat year-on-year, our own what that means for Celanese though, maybe I should call that out, because I think it's important is actually, we expect our auto volumes to be up 15% next year versus where they were this year just really as driven by the mix that we have, again, the higher exposure that we have in EVs than we used to have. EVs have a higher kilogram per vehicle, the presence we have in lithium-ion battery separator films enhanced by the expansion in Bishop that will finish here at the end of the year.
So again, industry-wide, we expect flat auto builds. We expect though our volume into auto to continue to grow by 15%. And I think your last question, Bob, but I had little problem hearing it, I think was really around elective procedures and medical -- for medical and what we're seeing there? [Speech Overlap]
Yeah. So what I would say is on medical, elective procedures have been flat this year. We kept calling out we expected them to increase, we also didn't expect the Delta variant, and so. What we're really seeing is, they're still flat. We're seeing a little bit of pickup in some regions. But I would say nothing of significance in terms of our orthopedic side of the medical business.
What I will say though is, we have seen a notable pickup in our business for other medical and pharma. And it's really on the back of our focus we put on this and our strategy in 2019 trying to expand our presence in other parts of medical and pharma. And we did see an increase in that in third quarter, which is really what helped kind of keep our mix pretty steady versus second quarter. And just, as an example of the kind of projects that we're bringing in now in medical outside of orthopedics, we've actually just closed the deal to provide POM into dry powder inhaler for a company in India. So this is for an inhaler, uses dry powder, uses our POM, this is a high value application, with pretty good, not just good margins, but good volume going forward.
So, that's really where we're starting to see more growth, higher margin business, things like inhalers, things like wearable diabetes devices, obviously still continuing to grow our vital dose, long dose delivery platforms. I mean, we are seeing really good growth in these segments and expect that to continue into next year and beyond.
