A future for SEBS based compounds in medical applications
ir. P.A.M. Traa, Wittenburg bv
SEBS block copolymers are thermoplastic elastomers that combine the properties of thermoplastics and rubbers in one polymer. The SEBS-polymers can not be used in a pure form but have to be compounded with others materals to make them suitable for processing. The SEBS polymers are very pure and therfore an excellent base for a great variety of products for use in the medical and pharmaceutical industry. Compounds of SEBS polymers are already used in a great ranges of totally different (medical)applications. Therefore it can be said that SEBS compounds are a versatile material. This is owed to the work of the compounder, who has been able to modify the SEBS polymers according to the wishes of the customers. The importance of a 'Custom compounder' becomes clear. New SEBS polymers are coming onto the market. This gives the compounder and the product-designer new opportunities in all kind of developments like e.g.: soft touch for engineering plastics, tie-layers for film applications, flexible polyolefines as an alternative for PVC, etc. Wittenburg have recently developed together with their customers, a wide range of materials that can be used as an alternative for glass, PVC and the semi-rigid polyolefines in e.g. IV-containers, CAPD-bags, bloodbags, etc. With this ranges of compounds, it is possible for the IV-bag producer to take part in the development of new applications, where the possibilities with soft-PVC stop.
