Ultraviolet (UV) masterbatches are additives used in the production of nonwoven fabrics to provide protection against the harmful effects of UV radiation. These masterbatches contain UV stabilizers or absorbers that help prevent degradation of the fabric when exposed to sunlight or other sources of UV radiation.

Nonwoven fabrics used in outdoor applications, such as agricultural covers, geotextiles, outdoor furniture, and automotive interiors, are often exposed to UV radiation. UV masterbatches can extend the lifespan of these fabrics by reducing UV-induced degradation and color fading.

Some UV masterbatches are designed to provide UV-blocking properties, which can be beneficial in applications where protection from UV radiation is critical, such as in healthcare settings or outdoor shelters.
