Polystone® P HG EHS black
PP
High-performance polypropylene especially for the Healthcare industry
In addition to its good hot steam sterilizability, this special material has good machinability and excellent chemical resistance. Polystone® P HG EHS is an isotactic, highly heat-stabilized polypropylene that is available as a homopolymer. This unique property profile makes it perfect for components for respiratory equipment or for applications in the pharmaceutical industry, either as a distribution unit, components for drug production or in chromatography.
Characteristics
- Good sterilisation resistance
- High rigidity
- ISO 10993-5 tested on semi-finished product
- Corrosion resistant
- Chemical resistant
