Applications
Injection molding takes the largest share. Consumer housings, automotive interior trim, and appliance parts in ABS and HIPS run in the 220–260°C range, well inside the masterbatch's thermal rating, and the no-color-spot dispersion specification protects the Class-A surfaces those parts are judged on. Comb strength retention lets molders color impact-modified grades without losing the drop-test performance the part was designed around.
Extrusion and blown film work depends on the same dispersion behavior for different reasons. In PE and PP film, an undispersed pigment agglomerate concentrates stress and initiates a bubble break, so the no-color-flow specification translates directly into line uptime. Coating and lamination lines see the same benefit at the die.
Fiber processing sets the hardest test. Spinning demands both the upper end of the temperature range and consistent particle geometry for accurate gravimetric feeding, which is why the product ships as uniform cylindrical pellets. Migration resistance at grade 4 or above matters here and in any application where the colored part contacts packaging, adjacent components, or textiles over its service life.
Blow molding, vacuum forming, and granulation round out the process set. For compounders producing pre-colored pellets, the 1:20 to 1:50 let-down range gives room to hit target loading without over-diluting the base resin, and the sun resistance rating of 5–8 supports outdoor containers, garden products, and building components exposed to daylight.
Why Choose BASTONE
BASTONE manufactures this masterbatch — the product is not resold. Compounding, pelletizing, dispersion checks, and color verification happen at the Hangzhou facility under BASTONE's own quality control, so a buyer raising a color deviation or a dispersion complaint reaches the people who ran the line, not a trading desk relaying a message to an unnamed plant.
Formulation depth comes from the group structure. BASTONE operates four production sites and one R&D center staffed by chemists who develop pigment packages and carrier systems in-house. Custom color work — matching a customer standard, changing carrier resin, or adjusting the let-down ratio to fit an existing feeder setup — happens in BASTONE's own lab, and sample batches come off the same equipment that will run production.
Buying direct from the manufacturer removes the trading-house markup that sits on most Chinese masterbatch exports. Zhejiang Bastone Technology Co., Ltd handles the export side with 10+ years of documentation and logistics experience across the group's chemical portfolio, so trade terms, packaging format, and shipping arrangements adapt to the buyer's requirements rather than a fixed template.
