When recycling multiple types of plastics together, one of the biggest challenges is achieving effective homogenization. Different polymers have varying polarity and energy profiles, which makes them fundamentally incompatible. This incompatibility leads to poor adhesion at phase boundaries, resulting in brittle, low-quality recycled products. That’s where compatibilizers come in. These specialized additives act like interfacial mediators, improving the interaction between otherwise incompatible polymers. By reducing the size of dispersed phases and enhancing adhesion at the boundaries, compatibilizers help create a consistent, well-integrated blend. This means the recycled material can have better mechanical properties, such as increased toughness, اکسیر پلیمر elongation, and impact resistance. Compatibilizers are especially valuable in recycling streams that contain frequently co-occurring pairs such as PE. They can be either amphiphilic polymers, functionalized copolymers, or in-situ coupling agents. The use of compatibilizers doesn’t just improve the quality of recycled plastics—it also enables cost-effective processing of contaminated plastic streams. As recycling technologies evolve, compatibilizers are becoming an essential tool in turning complex plastic waste into valuable new materials, helping close the loop in a circular economy.
