PP masterbatch different functions in the selection of paints, performance is different, the following were introduced, how to choose a pigment masterbatch function:

Heat-resistant PP masterbatch chosen pigment, a basic requirement withstand polypropylene fiber production process temperature to maintain its stable performance. Temperature requirements for the above temperature is generally 270 ~ 280 ℃.

PP masterbatch dispersion of pigment dispersion should be fine, but in the masterbatch to be dispersed evenly, and dispersant use does not reduce the quality of polypropylene fibers. Or can not produce a good quality liquid coloring fibers, running it is not stable, easy to break or abnormal fibers during fiber drawing.

Brightness polypropylene liquid coloring a variety of purposes, including fabric and knitted fabric for bedspreads, requires bright colors, because organic pigment relatively bright, colorful, and easy to color, so any use for these purposes need to use organic pigments.

Light resistance under the effect of light and some pigments sensitive to light, the colored fibers fade and brittle damage, pigment lightfastness and substantially related to its chemical structure, so in the production of polypropylene masterbatch full attention to pigment lightfastness lightfastness when a pigment is required, consider adding an ultraviolet absorber.

PP masterbatch pigment stability used for coloring polypropylene fibers have good stability. Means colored polymer fibers by prolonged exposure to heat, light or subjected to high temperatures pigment does not react with the fiber to form a new chemical groups to make Crimson low polymer properties.
