Nonwoven fibres are used in applications including surgical gowns and masks, sterilization bags, medical filtration products, and a range of sanitary and hygienic pads, and wound-care dressings.

Since pigments and additives used to colour or modify the polymer potentially increase the risk of extraction and interaction if the products come in contact with bodily fluids, these applications often require extraction and biological evaluation to standards such as US Pharmacopeia (USP) <87>,<88> or similar, the manufacturer reports.

MEVOPUR masterbatches

Clariant MEVOPUR masterbatches and compounds are designed to provide the makers of medical and pharmaceutical products with change-controlled, raw material additives and masterbatches, complete with regulatory documentation to support their use in healthcare applications.

Every MEVOPUR product is said to combine excellent application performance with documentation of the biological evaluation of its raw material ingredients to USP chapters (Class VI) and ISO10993 requirements, according to the company.

Expanding line

MEVOPUR colour and additive masterbatches are now available in seven ISO10993/USP colours (yellow, orange, red, violet, dark blue, mid blue, and green). New MEVOPUR masterbatch options, including custom colours, are also available for use with polyethylene (PE) bi-component fibres.

“Our product line continues to expand and evolve, now meeting customer demand for change-controlled raw material ingredients that comply with stringent medical requirements, and helping manufacturers find new alternatives for creating more colourful, comfortable, and functional medical and hygienic products,” commented Francis Baud, Global Fiber Marketing Head for the Clariant Masterbatches business unit.

Clariant MEVOPUR products are manufactured in three sites under global quality system ISO13485 to ensuring quick delivery and competitive pricing, with back-up capacity to meet the BCP (Business Continuity Planning) requirements of global customers. All MEVOPUR products are also free from animal derived substances and phthalates, and are suited for food contact, according to EU and FDA norms.
