Polymer matrix composites used for different cable coatings or pipes, are fabricated from materials containing various kinds of powder fillers or fibrous. Properties and structure of these materials depend on the type of added ingredients, their miscibility and quantity. Proper processing method also plays an important role, which allows for obtaining products of homogeneous reproducible properties. The composition was prepared by extrusion with changed processing parameters according to solid plastics. The roughness of obtained shapes was measured with the use of linear method. Results shows that adding blowing agent has a significant influence on mechanical properties.

The article investigates cluster approach to arrange economic policy in world countries. Cluster implication is discussed as a formation with its specifics and main characteristics. Cluster policy contents, essence, goals, types and differences are reviewed. Practical implementation of cluster policy in leading European countries is researched; problems and achieved results are determined. The problem of identifying and building up cluster formations is debated. Challenges and prospects for creating territorial clusters are determined together with cluster policy implementation in Ukraine as well as public and regional policy in supporting clusters’ development is reviewed. The article proves that public authority bodies’ activities in the sphere of cluster model implementation for Ukrainian industry development should be directed on activating the government role in cluster formation on the basis of public-private partnership as well as on creating favorable macro-economic, information and legal-regulatory environment to develop cluster-type business networks.

The aim of this work was to evaluate the effect of shear plastic into the mold cavity with a variable height on the structure and selected properties of molded parts. It was used as a special designed mold for producing test samples with varying thickness. It was shown, that the wall thickness of the molded part can significantly affect its properties, not only because of the greater volume of the amount of material, but also because of the process taking place within the the molded part during the solidification of the material. The degree of crystallinity can be different depending on the cooling time, which may contributes to the change in strength.
