Antioxidant Systems for Polyolefins
Antioxidant Systems for Polyolefins Antioxidant Systems Polyolefins are a cornerstone of polymer stabilization, particularly in applications where polyethylene (PE) and polypropylene (PP) dominate. In industrial and commercial sectors, polyolefins are widely used due to their versatility, low cost, and mechanical performance. However, their hydrocarbon backbone makes them highly susceptible to thermo-oxidative degradation. This degradation can […]
Stabilizer Packages for Recycled Polyolefins
Stabilizer Packages are essential for maintaining the quality and performance of recycled polyolefins such as polyethylene (PE) and polypropylene (PP). During recycling and multiple processing cycles, these polymers are prone to thermal, oxidative, and UV degradation. Proper stabilizer systems protect material properties and extend the service life of recycled polyolefins. Challenges in Recycled Polyolefins Recycled […]
5 Key Roles of Chain Extenders in Recycled Polyolefins
Chain Extenders are essential functional additives used to restore and enhance the properties of recycled polyolefins such as polyethylene and polypropylene. During mechanical recycling, repeated thermal and shear stresses lead to polymer chain scission, resulting in reduced molecular weight and inferior material performance. The use of chain extension technology allows recyclers to overcome these limitations […]
