The liquid wood heat flow and material properties as a function of temperature

There are three types of 'liquid wood', Arbofill, Arboblend and Arboform and will replace plastics materials in the near future taking into account the biodegradability and higher properties versus common used plastics materials. In order to get more information about the materials properties of 'liquid wood' the granules and samples obtained by injection molding were studied using Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA) for Arboform L,V3 Nature-'liquid wood' (A-LW) and Arboform L, V3 Nature reinforced with Aramid Fibers (A-LWAF).In case of A-LW granule studied, the DSC analysis presents that at 97 °C appears an endoderm peak which represents the crystallization of the material, at 175 °C the exoderm peak which means the melting point of the material. After the tested granule cooling period of time this one was tested again and the endoderm peak disappears, which means that crystallization of material disappeared. The melting point of the second test decreases slightly at 174.6 °C. Also, the new test shows that at 61.7 °C the glass transition temperature appears and the melting point slightly decreases. In case of A-LW samples the DSC analyses shows that the melting point increased by 2.77 °C compared to the melting point of Arboform granule. The material behavior is more or less the same without the crystallization area.
