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 impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
