Describe why fillers and other additives may increase or, in some cases, decrease rotomolded part mechanical properties
What will be an ideal response?
Fillers can increase mechanical properties by reducing the degradation that occurs during some heating cycles. Fillers can decrease mechanical properties by decreasing the flowability of the resin and therefore preventing the resin from moving uniformly throughout the mold. Decreased mechanical properties would also occur if the filler interferes with the fusion of the plastic particles.
