Grafted Polymers

Grafted Polymers are co polymers which has reactive functional group grafted over linear backbone of polymeric chain. Grafted Polymer works as Impact Modifier, Coupling Agent and Compatibilizer in various polymers like PP, PE, PC, PBT, Nylon, ABS etc. It helps in increasing mechanical properties like Izod Impact, Tensile Strength, Elongation etc. It helps in coupling in glass reinforced compound and mineral filled compounds. Also, it helps in blending of two different polymers like PC-ABS, PC-PBT, Nylon-PP, HD-LD etc.

What is the Grafted Polymer? Grafted Polymers are co polymers which has reactive functional group (commonly MAH or Acrylates) grafted over linear backbone of polymeric chain. What are the applications of Grafted Polymer? Grafted Polymers are used as Impact Modifiers, Coupling Agents, Compatibilizers and modifiers for polymers, their blends, filled and fiber-reinforced compounds based on PP, LD, HD, PC, PBT, Nylon, SAN, and Bioplastics (PLA/PBAT/PBS) etc. Polymer and metal bonding (like metal inserted plastic parts) also improves by adding few percent of grafted polymer during molding. It enhances melt strength significantly in biodegradable plastics. How does it work? Grafted Polymer’s polar functional groups attaches with other polymer’s chain or with non-polar fillers/fibers to provide interfacial adhesion hence improves compound's physical, morphological, and mechanical properties. Can we blend two different polymers? Generally, two different polymers are immiscible and to make perfect blend we require some compatibilizer. Grafted polymer works as compatibilizer, it helps in blending of two different polymers like PC-ABS, PC-PBT, Nylon-PP, HD-LD, PP-HD etc. Can it increase Izod Impact? Yes, it can increase | zod Impact in PC, PBT, Nylon, PET, PP etc. by addition of 2-5% of polymer weight. Can it increase Tensile Strength? Yes, thanks to its coupling mechanism it can increase the tensile strength of glass fiber reinforced or filled PP, PBT, Nylon, and PE etc. Can it improve recyclability? Yes, Grafted Polymer plays a vital role in recycling industry. It regenerates the polymer by improving its physical, morphological, and mechanical properties. Volatile content of end product cut down drastically and aesthetic/surface properties also improves. A good value addition can be put in recycled polymer by adding few percent of Grafted Polymer. Can it help in increasing filler loading? Yes, as it improves interfacial adhesion between polymer and filler, one can load high filler without compromising mechanical & rheological properties and surface finish of the compound.
