Abstract of Polymeren in medische toepassingen - 1999      1999

A future for SEBS based compounds in medical applications

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.

Medische hulpmiddelen moeten sinds 14 juni 1998 voldoen aan de richtlijn 93/42/EEG van de Raad van 14 juni betreffende medische hulpmiddelen. Behalve dat de vervaardiging van hulpmiddelen moet voldoen aan bepaalde kwaliteitssysteemeisen, moet de conformiteit van het hulpmiddel met de van toepassing zijnde essenti

Het pro-actief ontwerpen van kunststof producten voor de medische sector

Er zal een ontwerpprocedure worden beschreven, waarin vanaf het begin van de ontwerpfase rekening wordt gehouden met de invloed van de verschillende sterilisatiemethoden op het product. Dit zal worden toegelicht aan de hand van een aantal praktijkvoorbeeld. - Analyse van de critische ontwerp/funktiecharacteriestieken - Bepaling van passende/relevante testmethoden - Vergelijking van de producteigenschappen v

Life-span determination of medical devices

This presentation will outline some of the procedures commonly used to assess the useful life-span on medical devices. It will describe, with refence to examples, cases in which inappropriate material selection or processing has rendered the device unfit for its intended purpose. In addition, some attention will be given to programes of ageing and shelf-life prediction.
Merrick will also be including a general overview of the position of a polymer consultancy such as Rapra as a resource to the medical industry.
