Q1: What is the primary application of Hostaperm T30 Color Paste?
A: Hostaperm T30 Color Paste is specifically formulated for coloring high-performance engineering thermoplastics, including polyamide (PA), polybutylene terephthalate (PBT), and polyphenylene sulfide (PPS), where thermal stability and pigment dispersion integrity are critical during high-temperature processing.
Q2: Is Hostaperm T30 suitable for food-contact applications?
A: Hostaperm T30 Color Paste is not pre-certified for food-contact use. Its suitability depends on final formulation compliance, regulatory review by the compounder or end-user, and adherence to applicable regional requirements—such as FDA 21 CFR or EU Framework Regulation (EC) No 1935/2004—after full system evaluation.
Q3: How should Hostaperm T30 be incorporated into thermoplastic compounds?
A: It is typically added via gravimetric or volumetric dosing directly into the extruder feed throat or melt stream. Pre-blending with carrier resin is optional but may improve dispersion uniformity in sensitive formulations. Avoid excessive shear or prolonged residence time at peak temperatures to preserve pigment integrity.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 10 °C and 30 °C, away from direct sunlight and sources of heat or moisture. Ensure lids are tightly closed after each use to prevent skinning or viscosity change. Do not freeze.
Q5: Can Hostaperm T30 be used in halogen-free flame-retardant systems?
A: Yes—Hostaperm T30 demonstrates good compatibility with common halogen-free flame retardants (e.g., aluminum trihydrate, melamine polyphosphate) in PA and PBT compounds, provided pigment concentration and processing conditions are optimized to avoid adverse interactions affecting flame performance or color consistency.
