Fiber Colorants Discover our colorant portfolio for spun-dyed polyester, polyamide and polypropylene

They help make plastic parts opaque, but they don’t interfere with polymer colorants. The fine black powder is added at relatively high levels and creates only black-colored parts. They can withstand high temperatures and are resistant to most chemicals, abrasion and dirt2 and can be used with a range of colorants.
