Kaolin as Additive in Rice Husk Poly Propylene (RHPP) Composites

Easy availability, low cost and biodegradable nature of lignocellulosic materials necessitated the development of thermoplastic composites, based on commodity plastic such as Poly propylene (PP). It can be reinforced with rice husk, a type of lignocellulosic material abundantly available in nature. Preheating of rice husk and its proper size is beneficial for achieving good mechanical strength. Maleated polypropylene is used as compatibiliser for improving the bonding between rice husk and polypropylene. Effects of addition of Kaolin have been studied on the mechanical properties of RHPP composites. RHPP composite thus prepared have potential for applications as good building materials.
