Home Industries Materials Polymer Polymer Chemical Characterization Carbon Black Analyses Carbon Black Analyses Carbon black can be one of the most important raw materials in a rubber product formulation.
Carbon black, when doped in polymers, may reside at various sites, It may go substitution-ally into the polymer chains and composed charge transfer complexes (CTC), or may exist in the form of molecular aggregates between the polymer chains .
2019/4/19· Electrical percolation threshold of carbon black in a polymer matrix and its appliion to antistatic fibre. Choi HJ(1), Kim MS(1), Ahn D(1), Yeo SY(2), Lee S(3). Author information: (1)Technical Textile R&D Group, Korea Institute of Industrial Technology, 143
2000/7/27· The interaction between carbon black and the polymer, therefore, results in a loss of preferred conformation, conceivably because the polymer forms a strongly absorbed surface layer. From the infrared data, it appears that a high-structure carbon black such as XC72R can be absorbed on the elastomer surface and promote mostly trans conformation for the rubber structure.
Hyperjoint pins, created as an integral part of the metal component made using selective laser melting (SLM), feature a conical arrowhead shape that prevents pull-out.

Additive manufacturing techniques for ultraviolet (UV) curable silicones are investigated using a high-pressure extrusion apparatus. Manufacturing challenges encountered include the silicone slumping under its own weight, electrostatic repulsion between the printed part and the extrudate, clogging due to in-nozzle UV curing, and nozzle material accumulation.

New Clariant CESA®-IR additive masterbatches are now available to make dark-colored plastics visible to the near-infrared (NIR) sensors used in automated polymer sorting systems. While many companies use black packaging to brand their prestige products, the problems it poses in recycling systems has led to calls for black to be phased out of the palette. The new masterbatches help to resolve
Ketjenblack EC-600JD is a very pure carbon black extremely suitable for antistatic and electroconductive appliions. Due to its unique morphology and the extremely high surface area of approx. 1400 m2/g (BET), only one sixth the amount of Ketjenblack EC600-JD is needed compared to conventional electroconductive blacks in order to achieve the same conductivity.

At most carbon black concentrations, wear rate then becomes controlled by the rate of initial antiwear additive film formation, which for secondary ZDDP is very rapid, rather than by the kinetics of the abrasive process. From this understanding, strategies for It is

It is important that the carbon black or pigment particles are correctly dispersed in the polymer, and hence the final product, to ensure that the physical, mechanical and surface protection properties are maintained. Correct dispersion may also be an indiion that
Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining.
