Q1: What types of polymer systems is ERICW BC51001 Color Paste compatible with?
A: ERICW BC51001 is formulated for broad compatibility with thermoplastic resins including polyolefins (PP, PE), ABS, PS, and certain engineering plastics. Performance may vary depending on thermal stability and polarity of the base polymer — compatibility testing under actual processing conditions is recommended.
Q2: What is the typical dosage range for achieving target color intensity?
A: Dosage depends on the desired shade depth, base resin opacity, and processing method, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the polymer matrix. Start with lower levels and adjust incrementally to optimize dispersion and color consistency.
Q3: Does ERICW BC51001 require pre-drying before use in melt processing?
A: No pre-drying is typically required, as the paste is supplied in a non-volatile, solvent-free carrier system designed for direct incorporation into standard extrusion or injection molding operations. However, storage under dry, ambient conditions is advised to maintain optimal handling properties.
Q4: How stable is the colorant during high-temperature processing?
A: ERICW BC51001 is engineered for thermal stability up to typical polyolefin and styrenic processing temperatures. It maintains color integrity and shows minimal degradation or gas evolution under standard melt processing conditions — though extended residence times above 260 °C should be avoided without prior validation.
