Determining the properties
of wood plastic composites
(WPC) by thermal analysis
Wood plastic composites, also called wood polymer compounds,
consist of wood, polymers and additives. These compounds have
gained increasing acceptance over the past years. While currently
they are mainly used in non-structural components such as decking
or automotive interior elements, other application fields including
furniture, technical parts or consumer goods are becoming increasingly interesting. Thermal analysis methods such as thermogravimetry
(TGA), dynamic mechanical analysis (DMA) and dilatometry (DIL) are
very helpful in characterising the properties of WPC materials.

owadays, hardly any other
group of materials features
such high growth rates as WPC.
Worldwide production is predicted to
rise by about 58% between 2012 and
2015. Although North America is still
the leading production region, China
is expected to take over the top position next year. In Europe, production
growth is estimated at approximately
10% for 2015 [ 1].

Wood filling degrees ranging from
30% to max. 90% can be observed.
The higher the wood/polymer ratio,
the stiffer the material but, if the
wood content is above approximately
60 or 70%, the durability of the
material is reduced due to increased
fungal decay [ 2]. In case of a higher
wood proportion, wood properties
such as water uptake predominate.
Thermoplastics are very often used as
polymer matrix materials. The most
commonly used are polyolefins (PE,
PP) and polyvinyl chloride (PVC).
This paper focuses on WPC based on
PP.
