PRELIMINARY STUDY ON THE DIELECTRIC CONSTANT OF WPC BASED ON SOME TROPICAL WOODS.

Abstract

The use of wood plastic composites (WPC) as an important insulating material is studied by determining its dielectric constant. The variation of dielectric constant with moisture content is also investigated. Preliminary results show that all untreated woods studied have a higher dielectric constant than their polymer composites with the exception of Kapur and Keruing. It is therefore postulated that the presence of polymers has led to a decrease in the number of polarizable units. Such a material may be useful commercially.
