TPU Dark Blue Masterbatch is a TPU-specific colorant focusing on high-concentration color senseand industrial-grade weather resistance. It is prepared via a gradient temperature-controlled twin-screw extrusion process, using high-toughness TPU resin as the carrier, combined with copper phthalocyanine blue pigments with high hiding power and UV-resistant composite additives. Its core advantage lies in the rich and long-lasting dark blue performance: the pigment content is precisely proportioned, enabling it to present a thick dark blue hue like the deep sea. Its color concentration is 25% higher than that of ordinary blue masterbatches, and it disperses evenly in the TPU substrate. The surface of the finished product has no problems such as exposed bottom or grayish appearance, with full color and texture. Meanwhile, relying on the synergy of UV-resistant additives and weathering agents, its color difference ΔE is ≤2.0 after 3,000 hours of outdoor exposure. It can withstand temperature changes from -35℃ to 90℃, and will not experience color migration or fading when in contact with industrial media such as diesel oil and lubricating oil. Its application scenarios cover industrial manufacturing and high-end consumption fields, such as TPU weather-resistant seals for construction machinery, TPU anti-corrosion pipelines for marine equipment, and TPU waterproof zippersfor high-end outdoor clothing, combining industrial-grade durabilityand high-texture appearance.
