Preparation And Properties Of Rubber Seed Shell Flour (Rssf)- Filled Polypropylene (Pp) Composites

In this research, rubber seed shell flour (RSSF) was incorporated in polypropylene (PP) to determine the composites with optimum properties. RSSF loadings were varied from 10 php to 40 php to study the effect of adding RSSF on processing, tensile, morphological, flexural, impact, water absorption a...

The incorporation of RSSF in PP has increased the water absorption of the composites due to the presence of lignocelluloses in RSSF, which possibly creates hydrogen bonding with water.
