PP masterbatch is to first have excellent heat resistance, light resistance, efficient mobility and dispersion of toner and a certain percentage of efficient composite resin additives and special process semi-finished products made of a high concentration of masterbatch , and then to high melt index fiber grade polypropylene resin as a carrier resin , with uniformly mixed together , and then kneaded by a twin-screw extruder , made of plastics granulation . The biggest feature is the masterbatch with good quality stability , color uniformity , color less and particularly good dispersion. Toner content, add a small proportion , and processing resin compatibility , good processing performance, easy to change color , the filter value is low. Bright colors bright , heat resistance, light resistance, washable migration resistance, oil resistance , excellent spinnability . Especially for non-woven polypropylene , polypropylene filament , polypropylene staple fiber , polypropylene BCF yarn production use.

PP masterbatch advantage
1 . The pigment dispersion better in the products
Masterbatch pigment production process for thinning processing required to improve the dispersibility of pigment and color strength . Special varieties of the same plastic masterbatch carrier and the article , with good matching, the pigment particles can be well dispersed in the plastic article is heated to melt.
2 PP masterbatch pigment in favor of maintaining the chemical stability
Direct use of paint , then because of the storage and use of pigments in direct contact with the air , absorbing pigment occurs , oxidation phenomenon, made after the masterbatch, pigments and resin carrier due to air, moisture isolation , you can not make long-term quality of pigment changed.
3 PP masterbatch products to ensure color stability
Masterbatch resin particles similar to particles in the more convenient and accurate measurement , does not adhere to the container when mixing with the resin mixture is uniform, thus ensuring a stable amount , thus ensuring a stable color products .
Health polypropylene masterbatch protect operators of 4
Pigments are generally powder, adding and mixing easy flying , affect the health of the operator will be inhaled .

PP masterbatch performance requirements
Polypropylene is a pure hydrocarbon , a molecular chain containing a tertiary carbon atom , heat , light exposure at the tertiary carbon atoms of the molecule at the scissile make polypropylene quality deterioration , it requires a high temperature in the masterbatch formed spinning Ease of diffusion , without damaging the fiber quality , not the fiber fade, have excellent lightfastness , abrasion resistance, solvent resistance, withstand strict spindrawing .
( A ) the choice of the heat resistance of the pigment masterbatch , polypropylene basic requirement to withstand the temperature during fiber production , to maintain its stable performance . General requirements for the temperature above the temperature 270 ~ 280 ℃.
( 2 ) dispersion of masterbatch pigment dispersion should be fine, but in the masterbatch to be distributed evenly, and dispersant use will not reduce the quality of polypropylene fibers. Or can not produce good quality liquid coloring fibers, running is not stable, easy to break or abnormal fibers in the fiber drawing .
( 3 ) Brightness polypropylene liquid coloring a variety of purposes , including fabric and knitted fabrics for bedspreads , requires bright colors. Organic pigments because relatively bright and vivid , and easy to color , so any use of the above purposes need to use an organic pigment .
( 4 ) under the action of light resistance in the light of some pigments sensitive to light , so faded and brittle colored fiber loss, while pigment lightfastness basically related to its chemical structure , so full attention to the production of masterbatch pigment lightfastness when needed lightfastness pigment , ultraviolet absorber may be considered .
( 5 ) the stability of a pigment masterbatch used for coloring polypropylene fibers have excellent stability . This means that after prolonged exposure to the colored fiber polymer heat, light , or when subjected to high temperature pigment does not react with the fibers to form a new chemical groups make purple low polymer properties . So masterbatch should be used as a pure pigment , excluding iron, copper , lead and salt impurities , ensuring excellent physical properties of colored polypropylene fibers.
( 6 ) water resistance, dry-cleaning resistance, oil resistance , colored polypropylene in fiber products to be used and inevitable solvent after washing or dry cleaning, to be exposed to oil , particularly for the carpet , so the use of a colorant to there are good
