Q1: What is the primary application field for Viscofil Violet BLN Color Paste?
A: Viscofil Violet BLN is specifically developed for coloring polyolefin-based packaging materials, including flexible films, blow-molded containers, and injection-molded closures—particularly where high transparency, excellent dispersion, and thermal stability during processing are required.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Viscofil Violet BLN is formulated to comply with global food-contact regulations for polyolefins, subject to final regulatory assessment in the target market and adherence to good manufacturing practices. Users must verify compliance with applicable local requirements before commercial use.
Q3: How should Viscofil Violet BLN be incorporated into polyolefin compounds?
A: It is typically added directly to the polymer melt during extrusion or injection molding using standard gravimetric or volumetric dosing systems. Pre-blending with carrier resin is not required, but thorough mixing ensures optimal dispersion and color uniformity.
Q4: What is the recommended dosage range for achieving consistent violet shades?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the polymer matrix.
Q5: Does Viscofil Violet BLN offer resistance to migration and blooming in thin-film applications?
A: Yes, the paste is engineered for strong pigment-polymer compatibility and demonstrates low tendency toward migration or surface blooming under standard storage and processing conditions—especially in PP and PE films processed at typical temperatures.
