Clariant Plastics and Coatings Healthcare Polymer Solutions announce a new family of ABS polymer compounds that offer makers of medical devices and pharmaceutical packaging enhanced functionality without compromising on compliance with regulatory requirements. The resins are part of the MEVOPUR line of color and additive concentrates and ‘ready-to-use’ polymer compounds.

ABS (acrylonitrile-butadiene-styrene) is known as a versatile material that is commonly used in the consumer and automotive industry and now widely available as a ‘medical grade’ resin. Clariant is using its formulation skills, compounding capabilities in EN-ISO13485:2016 certified production facilities to enhance the ABS resin properties with pre-tested ingredients that support compliance to standards such as ISO10993 and USP Class VI.

“Clariant recently introduced the theme of ‘The Color of Innovation,’ to show how making decisions about materials early enough to apply QbD (Quality by Design) principles widens the scope of possibilities,” explains Steve Duckworth, global head of Marketing and Business Development. “We are known for color, but we also demonstrate what can be done to add new properties to polymers – such as medical-grade ABS – and widen the application possibilities for what is already an excellent resin.”

Examples of the MEVOPUR functional compounds include

ABS anti-scratch

ABS is often used for its visual appeal, but this can be spoiled in use by surface scratches. These scratches are particularly visible in dark colors. The new MEVOPUR compounds reduce the appearance of scratches, helping devices look good for longer.

ABS antistatic 

Plastics are insulators, and therefore prone to a build-up of static charges. In applications where plastics are in contact with powders, the powder can stick to the surface. In drug delivery devices, such as inhaler spacer chambers, this sticking effect reduces the dose reliability and repeatability. MEVOPUR permanent antistatic compounds reduce the surface resistivity and dissipate charges quickly, thereby eliminating sticking. Antistatic resins are available both in opaque colors and in transparent MABS (methyl methacrylate-acrylonitrile-butadiene-styrene).

ABS laser-welding transparent

According to professional welding services, laser welding involves two components – laser transmitting and laser absorbing materials. Polymers are usually transparent to the laser wavelengths and need to be modified, so they absorb laser energy. But colored pigments can also interfere with laser light transmission. These factors become a challenge when both components need to look the same. The new MEVOPUR compounds feature transparent colors (for example, blue) for both the laser transmitting and absorbing components.

ABS laser marking, high contrast

Laser-marking offers high speed, flexibility, and solvent-free marking on plastics. However, achieving a high-contrast, dark-mark on a light background can be a problem. The new MEVOPUR ABS white compound optimizes the contrast decreasing the time it takes to make a distinct mark.

“The ‘Color of Innovation’ is about bringing new ideas and capabilities to designers, but without sacrificing on regulatory compliance,” continues Duckworth. “This is why we say that MEVOPUR helps make every decision an opportunity.”

Introduced in 2010, the MEVOPUR product range celebrates ten years of helping medical-device and pharmaceutical companies reduce the risk of regulatory non-compliance throughout the product life cycle while meeting the highest standards for performance and appearance. All MEVOPUR materials are produced in three dedicated EN:ISO13485-2016 registered facilities and have been pre-tested to ensure compliance with common standards.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
