Black masterbatch for blown film, using high-quality resin as the carrier, high-quality organic pigment carbon black and additives, through high-speed banburying extrusion, air-cooled pelletizing, the product appearance is uniform and beautiful, cylindrical or oblate, The coloring is consistent, with good dispersibility, stability, and heat resistance. The surface of the blown film product has few crystal points and no cracks. At the same time, the film has excellent blackness and brightness.
Performance: high concentration, high brightness, uniform dispersion, strong coloring power.
According to the customer's demand for the appearance of the product, adjust the amount of addition. The company technically recommends adding 2%-5%, and special products add 5%-10%.
