Wood plastic composite material In this study some of the
important properties of experimentally manufactured wood–
plastic composites (WPC) were determined. Specimen having 60%
and 80% particle and fibre of radiata pine (Pinus radiata ) were
mixed with polypropylene (plastic) and four different additives,
namely Struktol TR 016 which is coupling agent, CIBA
antimicrobial agent (IRGAGUARD F3510) as fungicide, CIBA UV
filter coating (TINUVIN 123S), CIBA blue pigment (IRGALITE), and
their combinations. Based on the initial finding of this work
static bending properties of the samples enhanced as above
chemicals were added into both particle and fibre-based
specimens. Thickness swelling of the samples were also improved
with having additives in the panels. Micrographs taken on
scanning electron microscope (SEM) revealed that coupling agent
and pigment resulted in more homogeneous mixture of wood and
plastic together. Two surface roughness parameters average
roughness (Ra) and maximum roughness (Rmax) used to eva
