Application of carbodiimide as an anti-hydrolysis agent for bio-based TPU
Bio-based thermoplastic Polyurethane (TPU), also named bio-based polyurethane, has gained a lot of attention in recent years. However, it is possible that ester bond hydrolysis could occur during its usage. Hydrolysis means the chemical chain is broken under the influence of water. This problem can be solved by adding carbodiimide. We will share this information […]
A detailed look into the hydrolysis of polymers: Profound focus on Urethane Hydrolysis
Basic Hydrolysis of polymers The hydrolysis of polymers involves a chemical reaction in which water interacts directly with the polymer. This interaction breaks the bonds that hold it together, and reduces the polymer into monomers or smaller polymer chains called oligomers. This is the opposite of polymerization – the process that creates polymers by combining […]
