Coupling Agent Solutions for PP Composites
Quick Answer: Siya Polymer's maleic anhydride grafted PP coupling agents create a chemical bond between polar fillers (like glass fibre, wood flour, calcium carbonate or talc) and the non-polar polymer matrix, improving tensile strength, stiffness and surface finish.
When fillers or reinforcements such as glass fibre, wood flour, talc, calcium carbonate or mineral fillers are added to polypropylene, the polymer and the filler often don't bond well because PP is non-polar while most fillers are polar. Poor adhesion at this interface shows up as low tensile strength, weak flexural modulus, poor surface finish, fibre pull-out, and composites that fail well below their expected mechanical property targets. This is one of the most under-diagnosed problems in filled and reinforced compounds — manufacturers often blame the filler or the base resin when the real issue is missing interfacial bonding. Siya Polymer & Speciality Chemicals solves this at the chemistry level using coupling agents.
Siya Polymer's maleic anhydride grafted PP (MAPP) coupling agents create a chemical bridge between the polar filler surface and the non-polar PP matrix.
