This paper explores the use of Wollastonite, Cloisite 20A, Hollow Glass Micro Spheres and Precipitated Silica as reinforcing fillers in PE-BA-GMA compatibilized blends of Hytrel with HDPE (60:40). Wollastonite has been treated with 3-glycidyloxypropyl trimethoxysilane (GPTMS), and its effect on dispersion and hardness has been studied via SEM. I have tried to understand how the aspect ratio, size and surface property of the filler affect its tendency to cause nucleation, or reinforce the composites. These effects have been corroborated with the shore hardness, scratch hardness, other mechanical properties and flammability. Additionally, DSC has been used to study the degree of crystallinity of the composites, which has been correlated with the mechanical properties of these composites.
