HDPE is not recommended for purging
as it can cause delamination or lead to black specks.
Sink Marks

Machine related • Check for wear on screw, barrel or check ring
Delamination
• Purge barrel to eliminate material contamination
• Reduce sharp corners in material flow path
• Increase venting
Discoloration
Oversheared material
• Decrease melt temperature
• Reduce residence time
Mold design • Increase gate sizing
Dry material
• Check moisture of material to ensure it is within the
recommended moisture percentage for molding

MAGIQ FIBER COLORANTS -
MASTERBATCH PORTFOLIO
BLACK
• Standard and special products with high
pigment concentrations and excellent
tinting strength
• MBs at lower concentrations designed
to meet specific customer needs
• Black MB tailored for special requirements, with
particular physical/rheological properties
• Optimal melt flow properties allow a good
mixture with the polymer matrix yielding
the best possible spinnability
TECHNICAL ANALYSES
• DSC: Thermal analyses to characterize polymers, additives
and colorants
• TGA: Thermogravimetric analysis to evaluate thermal stability,
plus inorganic pigment, and carbon black content in the
Masterbatch
• FT-IR: Infrared spectroscopy for the analysis of raw materials
• Incineration oven to determine inorganic content
• Melt Flow Tester to measure the Melt Flow Rate of MBs
and Polymers
• Filter test to measure the dispersion quality and aggregate
content of materials contained in the polymer matrix
• Intrinsic/Relative Viscosity of Masterbatches and polymers
• Moisture content in the liquid colorants, MBs and polymers
• UV-Visible spectrometry: instrumental evaluation of the color
on yarn to perform quality control, color matchings and recipes
adjustments
• Yarn testing to evaluate mechanical properties, abrasion,
dry heat, rubbing and other characteristics
• Our pilot spinning lines have state-of-the-art take-up winders
that spin up to 4,500 meters/minute.
