Q1: What is the primary polymer carrier used in the REMAFIN EP New White Masterbatch range?
A: The REMAFIN EP New White Masterbatch range is formulated with a polyethylene (PE)-based carrier system, optimized for compatibility with PE and PP substrates in extrusion, blow molding, and injection molding applications.
Q2: How does this masterbatch achieve high whiteness and brightness without compromising thermal stability during processing?
A: REMAFIN EP New White leverages Clariant’s proprietary high-purity inorganic pigment dispersion technology, combined with thermally stable additives that minimize yellowing and maintain consistent chromatic performance across standard PE/PP processing temperatures.
Q3: What is the typical dosage range required to achieve full opacity and uniform white coloration in end products?
A: Dosage depends on base resin type, part thickness, and desired optical performance, but is generally effective within the range of 0.1% to 2% by weight—enabling efficient pigment utilization while supporting good melt flow and dispersion.
Q4: Is this masterbatch suitable for food-contact applications?
A: REMAFIN EP New White masterbatches are designed for non-food-contact industrial and consumer packaging applications. For food-contact use, please consult Clariant’s regulatory team to review applicable compliance documentation and formulation-specific assessments.
