Our premium PE-based grey masterbatch is formulated with high-grade composite inorganic and organic grey pigments with stable molecular structure. Unlike ordinary grey colorants that suffer from dull tones, color deviation and poor weather stability, this high-concentration grey masterbatch delivers neutral, smooth and uniform grey shades with excellent color purity. Boasting remarkable weather resistance, it can effectively resist UV radiation and outdoor environmental erosion, preventing finished plastic products from fading, discoloration or color deterioration after long-term indoor and outdoor use. During high-temperature plastic processing, the masterbatch shows excellent compatibility with virgin PE resin, enabling full and even pigment diffusion inside the plastic substrate. It avoids typical processing flaws including fisheyes, surface streaks, pigment accumulation and patchy coloring, ensuring sleek and flawless surface finishes for all molded plastic products.
With reliable thermal stability reaching over 260°C, this PE grey masterbatch fully adapts to the high-temperature working conditions of PE blown film, precision plastic injection and pipe extrusion processes. It will not decompose, discolor or produce harmful impurities during thermoplastic molding, guaranteeing stable processing quality and high-standard finished products. Designed with regular free-flowing uniform pellets, the product fits modern automated feeding systems and high-speed mixing procedures on industrial production lines. It greatly improves overall processing efficiency, reduces manual operation errors and lowers the defective product rate during large-scale continuous production.
This eco-friendly grey masterbatch features stable physical and chemical properties and will not weaken or damage the inherent mechanical performance of PE materials. It perfectly retains the original toughness, tensile strength and structural stability of plastic end products without causing brittleness or structural deformation. Supported by high pigment concentration and efficient tinting performance, the recommended addition ratio is 1% to 5%, which can be flexibly adjusted according to the target grey depth and personalized product requirements. It covers extensive application scenarios, including PE blown film goods, injection-molded plastic parts, PE extrusion pipes, various plastic packaging materials and household plastic supplies, satisfying general and high-standard coloring demands for both civil and industrial plastic processing fields.

To obtain consistent and high-quality grey coloring effects, fully and evenly pre-mix the PE grey masterbatch with pure PE resin before official production. This product is sensitive to moisture, so please keep the processing environment dry and well-ventilated. Unused masterbatch should be tightly sealed and stored in a cool, dry place to prevent moisture absorption and dust contamination, so as to maintain stable dispersion and coloring performance for future use.
