With the increasing pursuit of functional and environmentally friendly plastic products, photodegradable masterbatch is widely used in PE, PP, and other material systems due to its combined coloring and biodegradability.
In the plastic product manufacturing chain, the coloring process is not only a crucial step in giving products an aesthetically pleasing appearance, but also a core process that determines material performance and cost control.
In processing steps such as high-temperature melt extrusion, if photosensitizers undergo thermal decomposition or phase change, the number of their photoactive centers will be sharply reduced, thereby weakening the photodegradability of the final product.
The feeding rate needs to be dynamically adjusted according to the melting characteristics of the resin and the carbon black content to avoid fluctuations in melt pressure caused by uneven feeding, which in turn affects the surface quality and dimensional
In plastic processing, filler masterbatch is widely used in polyolefin products such as PE and PP due to its low cost, uniform coloring, and good processability.
Photodegradable masterbatch emerges as a compelling innovation that bridges this gap. Designed primarily for coloring polyethylene (PE), polypropylene (PP), and other common thermoplastics, this additive not only imparts vibrant, consistent hues but also
