Covestro polycarbonate used by Merz for Cellfina system

February 12/2018

MOSCOW (MRC) -- Covestro AG offers a range of medical-grade materials that help todays medical device manufacturers meet physical, chemical and environmental requirements, as per Worldofchemicals.

Chemical resistance and flame retardancy are key factors in material selection for medical equipment housings. Makroblend M4000 FR PC+PBT blend offers flame retardancy of V-0 at a thickness of 2 millimetres in the UL94 safety of flammability standard of Underwriters Laboratories, and 5VA at a thickness of 3 millimetres, and has superior chemical resistance.

The material is appropriate for skin contact applications and is biocompatible according to ISO 10993-5 (cytotoxicity) and ISO10993-10 (irritation and sensitization). Other advantages include high toughness, reduced susceptibility to stress cracking, good flowability and high tensile modulus.

Due to these outstanding properties, Merz Pharma, a global aesthetics and neurotoxin company selected Makroblend M4000 FR PC+PBT blend from Covestro for the housing of the motor module of its Cellfina System. It is the only FDA-cleared, minimally invasive procedure shown to improve the appearance of cellulite for up to three years.

We worked closely with Merz to select high-quality, proven materials for the system by providing chemical data, test plaques and custom colour matching. The motor module is disinfected between uses with aggressive disinfectant wipes and needed the superior chemical resistance provided by the polycarbonate blend. This combined with the flame retardance of the material made it a superior choice for the product, said Richard Aldrich, business development manager Southwest region, polycarbonates, Covestro LLC.
