Q1: What is the primary chemical nature of BASF 385/ 2B Pigment?
A: BASF 385/ 2B is an organic pigment based on the diketopyrrolopyrrole (DPP) chemical class, known for its high chromatic strength, excellent lightfastness, and thermal stability in polymer processing.
Q2: In which polymer systems is BASF 385/ 2B Pigment commonly used?
A: It is widely applied in engineering thermoplastics such as polyolefins (PP, PE), polyesters (PET, PBT), and polycarbonate, where it delivers consistent dispersion and resistance to melt degradation during extrusion and injection molding.
Q3: Is BASF 385/ 2B suitable for food-contact or regulatory-sensitive applications?
A: While not pre-approved for all food-contact uses by default, this pigment may be incorporated into compliant formulations upon evaluation against applicable regional regulations—customers should consult BASF’s regulatory support team and conduct final application-specific compliance testing.
Q4: How should BASF 385/ 2B be dispersed for optimal performance?
A: For best results, pre-dispersion using high-shear compounding or masterbatch preparation is recommended. Its particle morphology supports efficient wetting in non-polar and moderately polar resins, though resin-specific dispersants may further enhance stability and color development.
Q5: What are typical dosage levels when using BASF 385/ 2B in polymer coloring?
A: Dosage depends on formulation requirements and desired shade intensity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in final polymer products.
