Huntsman Corp. recently announced the start of commercial operation of a new methylene diphenyl diisocyanate (MDI) splitter at its Geismar site in Louisiana. 

Generally speaking, the hand dispensing of resins in prototypes is not a complicated process. Optimizing several factors will aid in the development of a transparent commercialization process, with straightforward resin dispensing and industrial dispensing equipment selection, all completed in an expedited timeframe.

A new polyol (PCD-b-PPG) has been synthesized that has a low viscosity of around 800-3,000 mPa·s (at 25˚C, liquid state) and is transparent due to the use of PCD as an initiator, even after storing for a long duration. The new PCD-b-PPG polyol can be applied to coating applications where transparency is required. In addition, it may contribute to other CASE applications and solvent-free urethane compositions that can take advantage of its low viscosity.

Automotive adhesive tapes are lighter than mechanical fasteners such as screws and fasteners and simplify the automobile manufacturing process. The global automotive adhesive tapes market was valued at $8.7 billion in 2020 and is expected to account for $13.8 billion by 2028.

Evonik recently announced that it has expanded with a new state-of-the-art polyurethane (PU) laboratory and innovation facility at its Essen Goldschmidt site in Germany.

Structural adhesives, also known as load-bearing adhesives, are substances that harden and fasten two similar or dissimilar substrate elements with high-modulus, high-strength, and permanent bonds.

You have a wide range of possibilities here. Normally, you would require an adhesive that has been toughened with a rubber for this.

When manufacturers are looking to use adhesives in an assembly operation, three steps must enter into the decision process: suitability, compatibility, and capability.
