| Popis: | This study focuses on a blend from the provider's SEBS extreme hardness (50% Shore-A 5 and 50% Shore-A 90) in order to analyze the miscibility of mixed materials from the storage of 2 references only. It has been used the thermoplastic elastomer Megol TA® SEBS, whose characteristics make it special due to the wide range of hardness and transparency. First step is injection of the extreme hardness virgin materials from the provider and the blend in a relation 50%-50% Next step is mechanical characterization of the blend, analyzing hardness, elongation at break and tensile strength. Finally, results are compared with original values of the materials incorporated. 1. INTRODUCTION. Styrene - ethylene - butadiene - styrene (SEBS) is a thermoplastic material which combines successfully the properties of an elastomer (rubber) with low costs of processing thermoplastics. Excellent resistance to aging of all compounds based on SEBS and flexibility in the formulation of the polymer allow the production of wide ranges of hardness for different applications in industry. It is remarkable its range of hardness and elastic modulus, excellent resistance to aging, very good processability at low temperatures and resistant to high temperatures. Injection molding is one of the different manufacturing processes that use this type of material, which is of great importance for the quantity of products that are made daily. The main objective of this study is the mechanical characterization of a blend from the provider's SEBS extreme hardness (50% Shore-A 5 and 50% Shore-A 90) in order to analyze the miscibility of mixed materials from the storage of 2 references only. |
