- Two options – Life Science Grade and Life Science Grade + Food Grade. Exhibits high stiffness and mechanical strength.
- Components are also sterilizable by means of steam (autoclave), dry heat, EtO, plasma, and gamma- & x-ray irradiation.
- Pre-assessed for biocompatibility on both resin and shape for up to 24 hours contact with body tissue according to USP VI and ISO 10993, as well as wetted contact in bioprocessing.
- Standard food approvals include FDA 21 CFR § 177.2415, while the FG type also includes Regulation (EU) No. 10/2011 food contact approval (which is based on food-related extractable & leaching tests).
- Excellent sterilization resistance via steam, dry heat, Ethylene Oxide, plasma, gamma and x-ray
- Unfilled PEEK base for high mechanical strength and chemical resistance
- Exceptional heat resistance

Handling (Machining) :
- During machining of the semi-finished products, evacuate swarf to prevent slipping or tripping hazard and observe the maximum allowable concentration of dust and
- formaldehyde levels on the workplace which apply in your country.
- Wear safety goggles during machining.
Storage:
- The products shall be stored indoors in a normal environment (air at 10 - 30°C / 30 - 70% RH) and kept away from any source of degradation such as sunlight, UV-lamps, chemicals (direct or indirect contact), ionizing radiation, flames, etc.
- Dimensional changes (camber, warpage, shrinkage …) of the products as well as slight color shifts of the external surfaces can occur with time.
- The latter does generally not pose a problem in case of semi-finished products since the surface-layer is mostly removed anyway upon machining them into finished parts.
Safety measures:
- Standard industrial safety recommendations shall be observed.
- Temperatures above the melting temperature shall be avoided.
