Q1: What is the primary application of ERICW 701YW0040G Color Paste?
A: ERICW 701YW0040G is a high-performance yellow color paste formulated for use in thermoplastic polymers, especially polyolefins (PP, PE) and engineering plastics such as ABS and PS. It is commonly employed in injection molding, extrusion, and blow molding applications where consistent hue, thermal stability, and dispersion efficiency are critical.
Q2: How should ERICW 701YW0040G be incorporated into polymer systems?
A: The paste is designed for direct addition to base resins using standard compounding equipment. It typically requires minimal pre-mixing and achieves excellent dispersion under standard melt-processing conditions. For optimal results, it is recommended to avoid excessive shear or prolonged residence time at elevated temperatures beyond typical processing windows.
Q3: Is ERICW 701YW0040G suitable for food-contact or medical-grade applications?
A: ERICW 701YW0040G is not pre-qualified for regulated food-contact or medical applications. Its suitability for such uses depends on full formulation evaluation, including compatibility with the final polymer matrix and compliance with applicable regional regulatory requirements. Customers must conduct their own due diligence and validation testing prior to use in sensitive applications.
Q4: What is the recommended dosage range for achieving target color strength?
A: Dosage depends on the base polymer, desired shade intensity, and processing method. In most polyolefin applications, effective loading generally ranges from 0.1% to 2% by weight relative to the total compound. Lower concentrations are often sufficient for light tints, while deeper shades may require higher additions—always verify via small-scale trials first.
Q5: Does ERICW 701YW0040G contain heavy metals or halogenated compounds?
A: ERICW 701YW0040G is formulated without intentionally added lead, cadmium, mercury, or hexavalent chromium, and does not contain halogenated organic pigments. It complies with common industry expectations for RoHS-conformant colorants, though final regulatory compliance is subject to the complete finished article and applicable jurisdictional requirements.
