The polyurethane materials used today are tough, resilient, and very stable to environmental factors in any environment, are widely used in industry, and can also be used as packaging materials. However, the durability of this pure polyurethane also has a negative side, that is, polyurethane is difficult to degrade as a packaging material. The successful development of this new product has opened up a new way to solve this problem. (China Chemical Industry News)
Russian and Ukrainian researchers recently successfully developed a biodegradable polyurethane (PU) based composite. The researchers added microcrystalline cellulose powder to polyurethane, which is biodegradable and well compatible with polyurethane. Therefore, when the television or computer packaging material is processed, microorganisms can eat the cellulose particles therein, and the entire material becomes dust.
