Swiss specialty-chemicals developer Clariant and its Masterbatches business unit announce a range of MEVOPUR® color and functional additives for use in high-performance, spunbond fibers used in medical applications.
Nonwoven fibers are used in applications including surgical gowns and masks, sterilization bags, medical filtration products, sanitary and hygienic pads and wound-care dressings. Since pigments and additives used to color 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 U.S. Pharmacopeia (USP) <87>,<88> or similar. Every MEVOPUR product offers documentation of the biological evaluation of its raw material ingredients to USP chapters (Class VI) and ISO10993 requirements.
MEVOPUR color and additive Masterbatches are now available in seven ISO10993/USP colors. New MEVOPUR Masterbatch options, including custom colors, are also available for use with polyethylene (PE) bi-component fibers.
