A high-purity cardanol derived from renewable cashew nutshell liquid offers chemical features that can be successfully used in epoxy and polyurethane adhesives and sealants.
Cashew nutshell liquid (CNSL) is a non-edible, bio-based material commonly used as a building block for various resins, hardeners, and modifiers in the adhesives, coatings, and composites industries. A high-purity cardanol, 3-pentadeca-dienyl-phenol, derived from the bio-oil CNSL has been employed to replace nonyl phenol (NP) in various applications, including isocyanate blocking.
Berry Global Group, Inc. recently announced that its Biesheim, France, facility has achieved an International Sustainability and Carbon Certificate (ISCC), which enables the site to sell ISCC Plus-certified nonwovens.
Adhesives play an important role in creating sustainable and resilient infrastructure. While the hybridization of adhesives is not a novel concept, recent innovations in raw materials have unlocked new possibilities for toughened epoxy systems.
When Kermit the Frog (voiced by Jim Henson) first sang “Bein’ Green” in 1970, few consumers were concerned about climate change. Most manufacturers didn’t focus on sustainability or tout their products’ “green” qualities (if they happened to have any). Oh, how times have changed.
Historically, about one-third of 3M’s annual sales come from products created in the past five years, so the impact is expected to expand greatly with each successive year.
3M recently announced that each 3M product entering the new product commercialization process will include a Sustainability Value Commitment that demonstrates how it drives impact for the greater good.
Sustainability and recyclability continue to be critical for adhesives in packaging applications, as does the need to continually improve efficiency and reduce cost.
As the corrugating industry’s workhorse, adhesives are diverse and cover a wide range of chemistries, forms, applications, and necessities. Packaging itself varies from heat-sealed polymers to plastics, foils, and paperboard.
As part of the U.S. Plastics Pact, activators like Henkel recognize that significant, system-wide change is imperative to realize a circular economy for plastics.
By 2050, the United Nations expects the global population to reach approximately 9.5 billion people. The expectations are that millions of people will be lifted out of poverty, increasing living standards and driving demand for chemical products.
