Researchers at Aalto University have developed a bio-based adhesive that can replace formaldehyde-containing adhesives in wood construction. The main raw material in the new adhesive is lignin, a structural component of wood and a by-product of the pulp industry that is usually burned after wood is processed.

Previously, lengthy and chemical-intensive pre-treatments have been necessary to use lignin in formaldehyde-free adhesives. The adhesive developed by Aalto University researchers can use purified kraft lignin and the chemical reaction to make the adhesive takes a few minutes instead of up to 10 hours.

Adhesives in this class offer thermal management and medium strength that supports the stiffness and mechanical performance of the battery pack.
By Catherine Veilleux on January 23, 2024 Batteries & EVs In EV battery manufacturing, adhesives are increasingly used to bond components. They are replacing mechanical fasteners as well various joining technologies. Unlike screws, bolts, and welding, structural adhesives provide a range of benefits beyond the bond.
For this reason, thermal adhesives are used at several locations in battery modules, such as between individual cells, or between cells and cooling plates. Structural adhesives are used in EV battery packs to create bonds that can withstand various environmental conditions and mechanical loads.
Battery adhesives come under various forms, such as liquids, pastes, gels, tapes, and pads. The distinct types of adhesives offer different benefits: Acrylic-based adhesives are known for their ability to bond a broad range of raw metals, composites, and thermoplastics.

Why do EV Batteries Contain Adhesives? EV battery adhesives connect the individual components while serving other roles like electrical insulation or conductors. These adhesives join individual battery cells, assemble battery modules, fix modules into packs, and act as electrical conduits between different sections.
The new adhesive, according to the researchers, contains 90% lignin versus previous lignin-based adhesives that feature just 20% to 50% lignin. In addition to being a potentially healthier and more carbon-friendly alternative for adhesives used in the manufacture of wood construction materials, the adhesive is strong and non-toxic ...

Both mobile homes and site-built homes have construction materials that contain formaldehyde, and both off-gas the formaldehyde during the first few months after placement. But, because a site-built home can take six months to a year from start to move-in day, much of the off-gassing has occurred while the home is under construction. Mobile ...

All wood has formaldehyde. That is why PB without urea formaldehyde glue is called NAF board: "no added formaldehyde", not formaldehyde free. Regarding the test, OSHA was happy to say the least. Our press area is well ventilated (we have a large dust collection system) and has 16 ft ceilings. Also, the process of pressing is pretty automated so ...

Discover how adhesives and sealants contribute to EV battery pack structural integrity, thermal management, and sustainability. Plus, see what qualities support manufacturing processes. High-performance thermal interface materials (TIM) increase manufacturing efficiency and can be easily repaired.
The risk of developing cancer from exposure to formaldehyde at concentrations found in most Canadian homes is very low. Health effects at different levels of formaldehyde. At low levels of formaldehyde (below 50 μg/m 3 or 40 ppb): no …
However, wood panels still use adhesives made from fossil raw materials. They contain formaldehyde, which can be harmful to health, especially for those working in the adhesive manufacturing process. People living in or visiting buildings can also be exposed to toxic formaldehyde from wood panels. Lignin, on the other hand, comes from wood ...

While listening to the healthy home podcast called ''Non-Toxic Environments'', I learned that wood glues, which are advertised as ''non-toxic,'' may be, in fact, very toxic. Particularly the ''less-toxic'' water-based wood glues! As I''m trying to improve the indoor air quality of my home, I asked a local carpenter to build a table so I…

Non-formaldehyde glue, as the name suggests, is a type of adhesive that does not contain formaldehyde, a potentially harmful chemical commonly found in traditional glues. Instead, it is made from soybeans, a renewable resource that is readily available and sustainable. When it comes to understanding non-formaldehyde glue, it is important to ...
The greater the exposure to products that contain formaldehyde in terms of both length of time and concentration, the higher the potential health risks. Individuals who have experienced ...
