Physical and Mechanical Properties of Composite Board Made fromWaste-Oil Palm Shell and Recycled Plastics
ABSTRACT
The needs of wood have been increasing due to the growing development in Indonesia. Consequently, the forests are getting severe damage. It has been causing the lack of raw material to the wooden based industries. Therefore, an alternative way is to find alternative material such as composite board made of waste-palm shell and recycled plastics. The kind of recycled plastics that used was recycled polypropylene (RPP). The board samples target density was 1.00 g/cm3. Composition of palm shell-particle and plastic were 40 : 60, 50 : 50, 60 : 40 and 70 : 30 based on particle oven dry weight with adding maleated polypropylene (MAPP) and without MAPP treatment. Weight of MAPP was 5% of RPP weight. Pressing temperature, melting time, pressing time were 1750C, 10 minutes and 2 minutes, respectively. The research results showed : Generally, the quality of boards with adding MAPP were better than boards without MAPP treatment, and the boards could be used for exterior application.
