Q1: What is the primary application area for Graphtol Red LC Pigment?
A: Graphtol Red LC Pigment is specifically developed for use in liquid colorant systems for plastics, particularly in polyolefins such as PP and PE, where high dispersion stability, low viscosity impact, and excellent heat stability are required.
Q2: Is Graphtol Red LC suitable for food-contact plastic applications?
A: Graphtol Red LC is designed to meet general regulatory expectations for pigments used in food-contact plastics; however, final compliance depends on the complete formulation, processing conditions, and applicable regional regulations—users must conduct full regulatory assessment and validation for their specific application.
Q3: How does Graphtol Red LC differ from conventional dry pigment powders?
A: Unlike dry pigments, Graphtol Red LC is supplied as a pre-dispersed liquid concentrate, offering improved handling safety, consistent dosing accuracy, reduced dust generation, and faster incorporation into polymer melts or masterbatch systems without requiring additional dispersion equipment.
Q4: What is the typical dosage range for Graphtol Red LC in polyolefin applications?
A: Dosage is formulation-dependent but generally ranges from 0.1% to 2% by weight relative to the base polymer, with optimal levels determined by target shade strength, opacity requirements, and processing conditions.
