Styrene TPES has three types of chips, powders and granules, which can be processed on common extrusion, blow molding, injection molding equipment. Since they do not require vulcanization, the initial investment in equipment is quite low. Styrene-based TPE injection molding has the advantage of a short cycle, and its production process is shorter and lower cost than rubber.
The cost of the mold (not requiring a large number of cavities) is much lower than that of rubber processing. In terms of processing, styrenic TPES, like other thermoplastic materials, can also be regenerated. Extrusion and coextrusion products of styrenic TPE block copolymers include: sheets, films, pipes, reinforced hoses, insulation and sheathing of wires and cables.
Styrene-based TPES adheres to many materials, including PS, PE, PP, PC, and EVA. For this reason, styrenic TPES is often used as a tie layer for coextruded sheets. Styrene/ethylene-butadiene/styrene block copolymers can be made into barrier packaging materials because they are transparent, thermoformable, cookable, and can be used in microwave ovens.
Styrene-based TPES can be used as a transparent thin coating to increase the coefficient of friction of many materials. Injection molded and blow molded styrene TPES components are widely used in the automotive, instrumentation and appliance industries. For such products, the use temperature and solvent resistance can be improved by blending the styrene/ethylene-butadiene/styrene block copolymer with the polyolefin.
