SBS – Polyflex

The ratio between the molecular weight of the polystyrene block and that of the butadiene affects the morphology of the elastomer and determines the final characteristics of the product. With a low content of polystyrene, the elastomer represents the continuous phase in which the polystyrene is dispersed. As the polystyrene content increases, the morphology of the rigid dispersed phase (polystyrene) changes from a structure with spheres to a structure with cylinders; the further increase in the quantity of polystyrene at first causes the formation of a lamellar structure, followed by a phase reversal during which the cylinders and then the polydiene spheres are dispersed in a polystyrene matrix. The mechanical properties of the co-polymers with styrene blocks are very similar (at ambient temperature) to those of vulcanized rubber, with typical ultimate strengths of 30 MPa and elongations up to 800%. SBS compounds are commonly used in applications where resistance to chemical agents and aging is not a decisive factor.

SEBS – Polyflex

The hydrogenation of an SBS rubber-whose elastomeric block contains at least 40% of 1.2 units – leads to the formation of an elastomeric segment in which ethylene units alternate statistically with butylene units (with gives it the name SEBS). These materials, which feature an excellent resistance to oxidation and to which large quantities of plasticizing agents and charges can be added, are used for the most part in the manufacture of technical articles, sports items and automobile passenger compartment components. Compounds made with SEBS are characterized byexcellent mechanical properties, good resistance to heat and to chemical agents. SEBS compounds offer excellent resistance to atmospheric agents, to UV rays and to ozone, thus representing the ideal choice for outdoor applications and in situations where the product is expected to last a long time.

TPV – Polyflex

During the course of the 1990s, EPDM was the most widely used elastomer (95%) in dynamic and semi-dynamic automotive insulation applications. However, around the beginning of 2000, the sector especially focused on a new material that offered pe rformances such as the EPDM, but that could be easily processed like thermoplastic material. Polyflex TPV is a dynamic mix between EPDM and polypropylene. Polyflex offers a combination of excellent thermoplastic and elastomeric properties, hardness, flexibility, elasticity. Thanks to its characteristics, TPV allows considerable savings during assembly of the finished pieces. TPV scrap is 100% recyclable and can be reworked. Thanks to Polyflex TPV, the weight of the moulded pieces can be reduced by 20-30%, thus cutting down on costs. Expensive secondary operations related to the finish can be reduced or even eliminated. The versatility of the TPV encourages the design of new systems and the consolidation of parts, so that other thermoplastic materials can be easily integrated and metal inserts can be eliminated. At the end of the process, the costs of finished parts are usually 20% lower compared to those of EPDM.
