SEBS High Gloss Physica and mechanical properties | ||||||||
SEBS styrenic block copolymer elastomers are some of the most versatile and easy to process materials in the plastics industry. The thermoplastic SEBS offers an excellent coefficient of surface friction, little permanent deformation, high tensile strength. Normally they do not require drying, they have wide processing latitudes and they have good to excellent thermal stability. Special qualities with specific acoustic properties, modified adhesion, higher thermal resistance and flame retardancy complete the current range of products. | ||||||||
SEBS High Gloss Thermal properties | ||||||||
The glass transition temperature (Tg) of the polybutadiene blocks is typically -90 ° C, while the Tg of the polystyrene blocks is + 100 ° C. Therefore, at any temperature between -90 ° C and + 100 ° C, SEBS will act as a physically cross-linked elastomer. The operating temperature is guaranteed from -40 ° C to + 100 ° C. | ||||||||
SEBS High Gloss Electrical Properties | ||||||||
SEBS thermoplastic are usually good insulators with a relatively high electrical resistivity, being the non-polar better than the polar ones. However, the electrical properties of SEBS polymer compounds are more dependent on the ingredients used in the formulation than on the base elastomer. We make ESBS polymer antistatic and even conductive by incorporating sufficient amounts of graphite, special types of carbon black, certain metallic powders or polar products into the rubber mixture. However, the conductivity obtained by these means does not resemble that of metals. | ||||||||
SEBS High Gloss Optical Properties | ||||||||
One of the characteristics of a two-phase system is that the light disperses when passing from one phase to another, resulting in different levels of light transmission, in the case of the SEBS pellets we also have transparent grades. | ||||||||
SEBS High Gloss Chemical properties | ||||||||
Unlike SBS, SEBS does not contain double bonds (which by their nature are sensitive to oxidation), which makes it particularly resistant to wear. Therefore, it is ideal for extreme conditions that have to do with heat, ultraviolet radiation, ozone or oxidizing agents. The SEBS resist well stress cracking to acids, hydroxides, methanol and ethanol, absorb oil, fats, aliphatic hydrocarbons. On the other hand, they do not avoid polar hydrocarbons, aromatic hydrocarbons, carboxylic acid, gasoline, ASTM oil No. 1 Paraffiic, ASTM Aromatic No. 3 oil, toluene and benzene. | ||||||||
SEBS High Gloss Processability | ||||||||
SEBS belong to the class of thermoplastic elastomers that possess the mechanical properties of rubber at room temperature and the processing capabilities of thermoplastics. The SEBS are similar to rubber without being cross-linked, so it is easy to process them to achieve useful shapes, usually it is processed more or less at 150-230 ° C. The SEBSs can present different characteristics, highlighting mainly its great versatility for bi-injection or overmolding with plastic materials. They can be processed with several methods, such as injection, extrusion or blowing. In addition, XPRENE HT has been created especially for marketing demands and meet customer requirements. | ||||||||
SEBS High Gloss Adhesion | ||||||||
Adhesion to a wide range of polar and non-polar substrates such as PP, PA, ABS, PC, PS, SAN, ASA, PBT, PET, ABS / PC etc. | ||||||||
SEBS High Gloss Applications | ||||||||
Typical applications are, profiles, household items, handles, knives, handles, accessories, feet, onsole storage, non-slip inserts, knobs, buttons, seals, profiles, pedal covers, power tools, seals for cables, plugs and sockets, cable coverings, switches, enclosures, garden tools, knobs, shock absorbers, fins, masks, caps, terminals, non-slip. | ||||||||
