PEBAs are plasticizer-free TPEs. The soft segment is the polyether and the hard segment is the polyamide (nylon). They are easy to process by injection molding and profile or film extrusion. Often they can be easily melt-blended with other polymers, and many compounders will provide custom products by doing this. Their chemistry allows them to achieve a wide range of physical and mechanical properties by varying the monomeric block types and ratios. [Pg.395]

The base polymer used for the stody was PEBA. It is a thermoplastic elastomer of hardness value 72 on Shore D. It consists of two domains -hard segment due to the presence of polyamide, and soft segment due to polyether. Changing the proportion of two domains it is possible to various hardness grades of PEBA. Its excellent cherrrical, mechanical, and physical properties and biocompatibility makes it one of the most widely used materials for biomedical devices. PEBA can be easily melt blended with many polymers. [Pg.1422]
