Abstract A composite of polyethylene terephthalate (PET) and hollow glass beads (HGB) with two different HGB sizes was prepared investigated rheologically. When the content reaches approximately 30 wt%, PET/HGB changes from a Newtonian fluid to pseudoplastic one within measured frequency range. If is below critical value, viscosity may be lower than that neat PET melt. This because scrolling or sliding in melt increases apparent shear rate reduces torque by rheometer rotor. Meanwhile, size affects composite. The 40 μm has more pronounced effect, resulting higher 50 HGB. Furthermore, containing density breaking volume fraction compared at same mass fraction. peak relaxation time content, temperatures correspond shorter times. DSC analysis showed addition filler decreased melting temperature increased crystallization material. Since longer pure PET, corresponding aggregates made chains HGBs are expected have larger characteristic These can determined using grid drawing method. coupling agent CS‐101 enhances bonding between evidenced comparing curves without agent. Highlights (PET)/hollow composites low levels might exhibit unusual viscosity. Abnormal molten occurs due rolling high solid‐like modulus plateau. proposed aggregate consists HGB, broken shards.
