Color Masterbatch for Power Strip Housing
Overview
Color Masterbatch for Power Strip Housing is a pre-dispersed pigment concentrate designed specifically for coloring plastic components in electrical safety equipment. It typically uses thermoplastic carriers like ABS, PC, or flame-retardant PP to ensure compatibility with injection molding processes. Engineered to meet stringent industry requirements, this masterbatch provides consistent coloration while maintaining the mechanical and electrical properties of the base polymer. Manufacturers value its ability to deliver precise color matching for brand differentiation and safety labeling purposes.
Physical and Chemical Properties
The masterbatch exhibits excellent thermal stability, withstanding processing temperatures up to 280°C without degradation – critical for power strip manufacturing where heat resistance is mandatory. Its formulation prevents pigment agglomeration, ensuring smooth surface finish on final products. Key technical parameters include a melt flow index (MFI) matched to the host resin, typically 10-30 g/10min (230°C/2.16kg). The pigments used demonstrate lightfastness of 7-8 on the Blue Scale and pass 750V dielectric strength tests, making them suitable for electrical applications.
Main Applications
Primary use is in coloring injection-molded power strip housings, where it provides uniform coloration and meets UL94 V-0 flame retardancy standards when combined with appropriate base resins. Secondary applications include circuit breaker casings and electrical connector components. The product enables manufacturers to comply with international safety color codes – for example, red for master circuit indicators or yellow for child-safe safety shutters. Custom formulations can incorporate anti-static or glow-in-the-dark properties for specialized applications.
Safety and Storage
While the processed material is non-hazardous, raw masterbatch granules require standard industrial hygiene practices during handling. Suppliers provide Material Safety Data Sheets (MSDS) documenting compliance with IEC 61249-2-21 standards for halogen content. Proper storage involves sealed moisture-proof packaging in ventilated areas below 30°C. Shelf life typically exceeds 12 months when stored correctly. Bulk containers should be rotated using FIFO (first-in-first-out) inventory management to prevent prolonged exposure to humidity.
B2B Procurement Guide
Industrial buyers should specify technical requirements including: color match to Pantone/RAL standards, minimum let-down ratio (commonly 1-4%), and compliance certificates (UL, CSA, CE). Sample batches for trial production are recommended before bulk orders. Leading manufacturers offer customized solutions with batch-to-batch color consistency ≤0.5 ΔE. MOQs typically start at 500kg, with lead times of 2-4 weeks for standard colors. Consider suppliers with in-house color matching labs and ISO 9001-certified production facilities for quality assurance.
