has introduced of an grade of ASA designed specifically for small medical device housings and casings. Luran S MED 797S SPF30 is the lastest member of INEOS Styrolution’s ASA product family. It reportedly offers strong chemical resistance, UV resistance, and impact strength.

Suitable for injection molding, Luran S is said to provide excellent flowability for easy processing. Luran S MED 797S SPF30, available in NR (Natur) and in white (WT000112),  is said to show excellent chemical resistance against alcohols (e.g. IPA, ethanol, propanol) or alcohol-based disinfectants. It also shows good resistance against quaternary ammonium or glutaral based disinfectants making it a material of choice for clinical environments.

High impact strength, specifically at room temperature and at lower temperatures (5°C), contribute to a better protection of devices, e.g. avoiding cracking failures when a device drops to the floor. INEOS says this particular performance trait makes Luran S MED 797S SPF30 a viable alternative to standard ABS materials.

Renewable Feedstock

The new Luran S grade is also available using renewable feedstock, based on a mass balance process certified under ISCC PLUS. Luran S ECO MED 797S SPF30 BC40 contains 40% renewable content resulting in a carbon footprint reduction of up to 52% compared to fossil-based Luran S.

Says Bernd Elbert, market development manager at INEOS Styrolution: “The market segment of small, mobile medical and hospital devices is growing rapidly. The properties of our new Luran S MED 797S SPF30 make it a very strong contender for device housings and casings in this specific category. I invite every application designer to explore our new product for their
next project.”
