Plastic bottles upcycled through chemical recycling have become Valox iQ PBT used to make the brackets of the side air deflection system in all seven models of Volvo's VN family of 2012 heavy trucks. (Source: SABIC Innovative Plastics)
notarboca, thanks for the explanation. We are discussing materials, here, not processes. I agree that the more it is used the greater the benefit. So far, all of these new materials are discovered and provided by commercial entities, so I'm not sure how they could be provided or distributed without without commercialization.
What I meant was if more manufacturers were using this, or a similar process, it would be of great benefit. Commercialization is very good, too; you discover the process, you can license it and profit from it.
notarboca, can you tell us what you mean? This material and Axion's material use in the Scottish bridge are both proprietary processes developed by industry and commercialized. What alternative method were you thinking of?
Great article. Is this the same genearl process / material that was discussed in a previous piece relating to bridge construction? It seems that there are more and more uses for this. Maybe, some day soon there will be profit in recycling and municipalities can subsidized their budgets out of recycling rather than having to pay for mandated programs.
bobjengr, glad you enjoyed the article. The SABIC representatives I met with mentioned that their Innovative Plastics division originated in the former GE group. I was really impressed with what SABIC has accomplished. That said, SABIC is a Saudi Arabian company, not an American one, without all of the constraints (even for beneficient reasons) American ones have and with many social and political conditions US engineers might not want to live with.
There was no mention of this specific material used for Volvo's side air deflection brackets also being used for under-hood applications (I would have reported it, since I'm interested in that application, too). SABIC did not say if it is developing a version of this material, or other materials, for that use. In what I've seen in the market to date, handling hot and cold air and handling under-hood temps are apps with two different sets of specs.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
