IMPROVING PERFORMANCE WITH RENEWABLE TECHNOLOGY
Cardolite offers a variety of cardanol grades and cardanol derivatives that can be used as monomer or polymer building blocks in specialty chemicals. Cardanol is the main component distilled from Cashew Nutshell Liquid (CNSL), an annually renewable and non-food chain phenolic resin extracted from the honeycomb of the cashew nut.
This material is a versatile molecule that can be functionalized in many different ways. Reactive sites include the phenolic OH, aromatic ring and double bonds of the long aliphatic side chain. Epoxy and polyol resins, ethoxylate surfactants, amines as curing agents, benzoxazines, and phenolic and polyester resins are just some examples of resins made from cardanol. For years, cardanol and its derivatives have been successfully used in the coatings, adhesives, composites, foam and friction industries due to their unique properties. Moreover, cardanol is a safer, non-toxic replacement for nonyl phenol and similar petro-based phenols.
Given the performance and health, environmental and safety benefits of cardanol, this material has also been used as modifier in many applications. For instance, cardanol can be a diluent, flexibilizer and accelerator for epoxy systems, an isocyanate blocking agent in polyurethanes, a plasticizer in plastics and PVC, and a dust suppressor in mixing processes.
