EUROPLEX PPSU is an extruded sheet material used for the manufacturing of sterilisation cases. PPSU is Polyphenylsulphone, an amorphous plastic. This material combines a high melting temperature with quite a low moisture absorption. Relative to other sulfones (plastics containing a sulphur-oxygen bond), PPSU has a high impact strength and dimensional stability as well as chemical resistance. The material is also resistant to detergents and disinfectants.
The sheets have a high heat distortion temperature up to 190 degrees Celsius, show excellent mechanical properties and chemical resistance and can be easily sterilized by superheated steam at over 1000 cycles.
Possible sheet varieties are available. Thicknesses range from 0.5 – 7.0 mm and in different transparent and opaque colours. The material is specifically usable for the manufacturing of sterilization boxes, trays and containers and other medical parts.
Characteristics include a higher operational temperature (up to 180°C), resistance to chemicals and hydrolysis. The plastic has good electrical insulating properties and favourable dielectric characteristics.
