1, the material used by the customer is recycled material: because the compatibility of recycled material is much worse than that of new material, and the customer purchases some general-purpose black masterbatch with relatively low requirements, after the test, the performance of general-purpose black masterbatch and the performance deviation possibility of recycled material is relatively more, so the possibility of black not black enough in the test results is more, (it is recommended that customers choose to use the corresponding black masterbatch according to the performance of raw materials)
2. The raw materials used by the customer are not as good as the black masterbatch performance taken by the customer; Some customers use modified materials, but the black masterbatch products he takes are universal, then naturally it is not right, because the masterbatch and the carrier of the modified material itself is already different, so the compatibility, diffusion problems are more, and the blackness will be greatly reduced. (It is recommended that customers take modified special black masterbatch products to use)
3. Customers habitually look at blackness; Usually, when changing raw material suppliers, many customers may prefer to look at the blackness of the masterbatch, and ignore the carrier of the black masterbatch, compatibility, diffusion, after the customer gets our black masterbatch, they will put the black masterbatch according to the proportion they used before, then the result will also lead to a lot of problems, it may be that the diffusion is not good, the compatibility deviation, then the result is that the blackness is not enough, (it is recommended that customers have a detailed understanding of each black masterbatch product before purchasing black masterbatch, Go to the sampling test again)
