VELOX partners with Trinseo to offer chemical-resistant blends for medical housings 7th February 2018
Increasingly aggressive desinfectants are being used to fight against hospital acquired infections (HAI) with some severe side effects for medical equipments. VELOX highlights Trinseo’s chemical resistant blends for medical housings which effectively maintain the durability and pleasing aesthetics of medical devices otherwise affected during cleaning processes.
Hospital Acquired Infections (HAI) continue to be a major concern globally. “At any given time, about 1 in 25 in-patients have an infection related to hospital care”, states The Office of Disease Prevention and Health Promotion (ODPHP) in the United States. “These infections lead to the loss of tensof thousands of lives and cost the US health care system billions of dollars each year.” Correspondingly, in its Annual Epidemiological Report 2016 the European Centre for Disease Prevention and Control reveals that “8% of patients staying in an intensive care unit (ICU) for more than two days presented with at least one ICU-acquired healthcare-associated infection (HAI) under surveillance.”
Use of aggressive chemicals to reduce HAI
The good news though is that steps are being taken to reduce the incidence of HAIs. And they are having a positive impact, with HAIs decreasing between 2008 and 2014. This is largely due to guidelines issued by the Centers for Disease Control in the United States recommending that non-critical medical equipment surfaces should be disinfected with an EPA-registered low-or intermediate-level disinfectantsuch as one of the following:
- Isopropyl Alcohol
- Phenolic Germicidal
- Iodophor Germicidal
- Quaternary Ammonium Compounds
Today’s medical device housings need to be exposed to powerful disinfectants and cleaners. More rigorous cleaning procedures, increasing aggressiveness of chemicals, and a move towards convenient wipes for more frequent cleaning have led to a substantially increased rate of medical equipment housing failures.
Need for chemical resistant plastics
While there have been changes in cleaning procedures, little change has taken place in materials or design. This has created a need for plastics that can withstand chemical aggressors. Trinseo, a manufacturer of innovative and sustainable plastics solutions, is one of the outriders in this field. “Trinseo’s chemical resistant EMERGE 9000 Advanced Resins series balances a unique combination of advanced properties while maintaining the durability and pleasing aesthetics needed for today’s medical treatment environment”, says Siobhan Bastiansen, Market Manager Medical Plastics at VELOX. As the distribution partner of Trinseo, VELOX offers the EMERGE 9000 Advanced Resins series for medical housings in all of Europe.
Trinseo’s EMERGE series
Trinseo’s Advanced Resin solutions combine the excellent processability of polycarbonate (PC) with selected polymers and additives such as ABS, PET, or colourants and deliver compounds and blends with special properties needed for a variety of applications. The grades are specially designed for environments where it is necessary to endure repeated exposure to a wide variety of aggressive chemicals, including surface disinfectants and cleaners.
Whether for passive housings or for powered housings, VELOX offers a specifically customised grade. EMERGE PC/PET 9100CR Advanced Resin is perfectly suited for passive housings and offers high levels of ultraviolet light resistance to help reduce potential colour shift, loss of surface gloss and property performance over time. It offers a UL HB rating at 1.0mm and is biocompatible. The EMERGE PC/PET 9500 on the other hand is an ignition-resistant blend with UL ratings of V-1 at 1.5 mm, V-0 at 2.0 mm, and 5 VA at 2.5 mm. This makes it an ideal material for devices that are powered and need to function in a demanding environment.
Common applications for the Advanced Resins series are patient monitoring equipment housings, medical imaging and diagnostic equipments, cabinet components and enclosures, home healthcare housings and monitoring, pumps, oxygenators as well as dental equipment housings.
“Trinseo’s EMERGE 9000 CR series not only meet the need for today’s medical housings to withstand powerful disinfectants and cleaners that can attack plastic surfaces, but also provide advanced properties required by manufacturers and moulders for a better functionality, reliability and a prolonged lifecycle of their products.
