Q1: What types of polymers is Hostasin Orange G 30 Color Paste compatible with?
A: Hostasin Orange G 30 is formulated for use in a broad range of thermoplastics, including polyolefins (e.g., PP and PE), PS, ABS, and certain engineering plastics. Compatibility should always be verified under actual processing conditions due to variations in resin grade, additives, and thermal history.
Q2: Is this color paste suitable for food-contact applications?
A: Hostasin Orange G 30 is designed for industrial and general-purpose applications. For food-contact use, formal regulatory approval must be obtained based on the final article’s composition, processing parameters, and applicable regional requirements — Clariant does not pre-certify end-use compliance.
Q3: How should the color paste be incorporated into polymer melts?
A: It is typically introduced via gravimetric or volumetric dosing systems directly into the extruder feed throat or injection molding hopper. Good dispersion is achieved under standard melt processing conditions; extended residence time or excessive shear should be avoided to preserve color integrity.
Q4: What is the recommended dosage range for achieving standard opacity and shade intensity?
A: Dosage depends on the base polymer, desired shade depth, and required opacity, but typical usage ranges from 0.1% to 2% by weight. Lower concentrations are often sufficient for light tints, while higher loadings may be needed for full coverage in opaque applications.
Q5: Does this color paste contain heavy metals or halogenated compounds?
A: Hostasin Orange G 30 is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, or hexavalent chromium) or halogenated organic carriers. Its composition aligns with common industry expectations for restricted substance management, though full compliance verification remains the responsibility of the compounder.
