First of all, in the field of application, there is a clear difference between the two, HDPE special black masterbatch is more used in pipelines, water pipes and other heavy-duty applications; LDPE special black masterbatch is more used in undershirt bags, garbage bags, shopping bags and other blown film molding of plastic products.


The difference between the two applications is determined by their physical properties, HDPE black masterbatch has a higher density, stiffness and strength, impact resistance and abrasion resistance, so it is more suitable for use in pipe piping; and HDPE black masterbatch flexibility, elasticity, low density, more suitable for making films and other lightweight applications.

There is also a conceptual difference between the two. black masterbatch for HDPE is a thermoplastic with high density, high strength and robustness. black masterbatch for LDPE is a low-density, low-strength, soft plastic. lDPE can be used to produce a wide range of films, garbage bags, packaging materials, and so on.


Blown film grade black masterbatches are made of carbon black and high quality, high color strength additives. They are extruded by high speed mixers and air cooled pellets. As a result, there are few fisheyes in blown film products. It is black and bright.


The advantages of black masterbatch for HDPE and black masterbatch for LDPE are:


Selecting high quality carbon black with stable nature.


2. Use organic toughening dispersant, processed and modified by special technology.


3. Good dispersibility. Optimized dispersant helps the diffusion of carbon black.


4. Good coloring, high brightness, high temperature resistance and good stability.


5. Comply with international health standard.


6. Customized carbon black content according to customer's requirement.


The advantages of this masterbatch are dust free, easy to flow, cheaper than compounding cost and takes up very little warehouse space.
