4. Conclusion
This article has assessed the rotomouldability of polyethylene foams and investigated the effect of foam content on
melt flow index and impact strength of rotationally moulded parts. Based on the experimental results, the following
conclusions may be drawn:
1. Melt flow index increases with increase in foaming content until 6%, after which it decreases.
2. Higher melt flow index at 6% indicates ease of melting and easy to process. But the material with this
behavior would have shorter chains and therefore low molecular weight and lower viscosity.
