Plastics are inseparable from the filling of the masterbatch during processing, but the masterbatch is a double-edged sword, and its dosage is very specific. In the case of the black masterbatch, if the amount added is too large, the cost of the plastic product increases, and the color of the product is destroyed; if the amount is too small, the black masterbatch of the antiaging additive and carbon black cannot be sufficiently integrated. Therefore, the amount of black masterbatch is an important technology.

  In the molding process of plastic products, almost everyone uses black masterbatch for dyeing, anti-aging, conductive products, etc., and many problems in use often trouble us. We now discuss some of the issues that everyone cares about and hope to benefit you.

1. What material is the black masterbatch made of?

The materials constituting the black masterbatch are: A. carbon black; B. carbon black carrier; C. carbon black wetting agent; D. carbon black dispersant; E. other processing aids.

2. Where does the black masterbatch excel?

In the dyeing of plastic products, the black masterbatch only needs 0.6%-0.8%, it will be very black, and the addition will not be darker. According to the test data, if the products used outdoors in Xinjiang need to rely on black masterbatch to prevent aging, just use high-quality black masterbatch (instead of returning the carrier, moistening the white oil, and supplementing calcium). Types of carbonate dispersions, etc.), the carbon black content in the product is 2-2.5%, that is, 5-6 weight parts of carbon black masterbatch accounts for 40% of raw materials per 100 kg, far exceeding any anti-aging products, Product life can reach more than 10 years. This is why drip products, water products and communication cable products are all black. In addition, carbon black has a special contribution to the improvement of the strength and electrical conductivity of the product.
