Abstract: In all the activity areas, the use of recycled materials has become an important trend. From this point of view, the liquid wood is the material that will replace plastic in the near future. There are three types of liquid wood as follow: arbofill, arboblend and arboform. Liquid wood can be reused up to five times over, without affecting the mechanical properties of the material, as for example fire resistance and durability. The liquid wood has a positive impact over the environment compared to petroleum-derived plastics.  In this paper, arboblend V2 nature is used. Experimental data show that the tensile strength reached 44.05 ± 0.48 MPa at 23°C and the material had a brittle behavior. The results obtained are better than PE-40 MPa, PVDF (poly vinylidene fluoride)-43 MPa, PCTFE (ethylene copolymer)-32 MPa. The friction coefficient registers a slight decrease approximately in the first 25 s and then throughout the completely tested period it registers a slight increase. The friction coefficient average using the disc rotating is 0.1627. Variation of friction coefficient is similar, the average friction coefficient being 0.1376. The results obtained are better than PA 12-(0.32-0.38); PP-0.3; PE-HD (high density polyethylene)-0.29; ABS- 0.5; PVDF (poly vinylidene fluoride)-0.23. Arboblend V2 nature seems to have a structure between amorphous and crystalline. Using software of machine equipment is determined the following phases with peaks highlighted, such as C14H26CuO12S2 with monoclinic crystal structure and another one with unknown crystal structure. The SEM analysis shows a uniform structure with small impurities with a random orientation. In the spectrum of chemical elements dominate, in percentage and atomic mass, carbon and oxygen followed by nitogen. According to the analyses performed and to the conclusions drawn, the arboblend V2 nature can replace the plastic materials in many industrial applications, such as the automobile industry, furniture industry, toys industry, electrical industry, computers, mobile phone, housing etc.
