Non-Black Compounds Choosing a reinforcing filler to replace carbon black for developing new non-black rubber products can be a difficult process. Physical properties for your black compound, like low compression-set and heat build-up, along with good abrasion resistance and tensile strength need to be similar for your new one.

In industry, carbon black is used as a filtration material and a filler/pigment in coatings, rubber, plastics, paints, carbon paper, and crayons. As a filler, carbon black increases resistance to abrasion and adds electrical conductivity. About one fourth of the weight of a standard automobile tire is carbon black.
This invention relates to a tire with a tread of rubber composition with reinforcing filler containing oxidized rubber reinforcing carbon black together with tris (2-ethyl hexyl) phosphate. In one embodiment, the invention relates to a truck tire intended for heavy duty performance with a tread rubber composition comprised of natural cis 1,4-polyisoprene rubber containing reinforcing filler ...
Carbon black is one of the most important filler in rubbers, especially for tires, to give the rubber material abrasion resistance and tensile strength. Carbon black particles are heavily prone to form aggregates which are difficult to disperse homogeneously. Carbon black is commonly used in paints, enamels, inks, nylon and plastic ...
Jun 01, 2012· Home » Recent Developments to Improve Scratch and Mar Resistance ... is much more limited even though alumina is significantly harder than silica-based materials and as a scratch and abrasion-resistant filler, ... becomes more and more important. For many decades, low-cost fillers (e.g., those based on CaCO 3, clay, quartz and carbon black) ...
In this study, N339 carbon black was used in place of N326 carbon black because it is a superior tread (better abrasion resistance) carbon black (table 6). The abrasion results are shown in figure 5. The N339 filled natural rubber compound exhibited better abrasion resistance than the Agilon filled compound at low slip angle.

Carbon black is a universal reinforcing filler and light stabilizer used in rubber compounds. Carbon black imparts strength and toughness to a tire as well as it improves the rubber's resistance to tearing, abrasion, flex fatigue and also increases traction and durability. A tire would last less than 5000 miles without the addition of carbon black.
which can be an alternative to the commonly used commercial carbon black filler with a consequent reduction in cost and may offer some new scientific knowledge and economic benefits [5]. ...

The primary rubber reinforcing fillers are carbon blacks ("black" fillers) and precipitated amorphous silicas ("white" fillers). Reinforcing "white" fillers such as Grace's PERKASIL ® precipitated silicas are effective in rubber formulations to add tear strength, abrasion resistance, and aging resistance to rubber products. Tires
TYPES OF COMMON CARBON BLACK : The highest volume use of carbon black is as a reinforcing filler in rubber products, especially tires. While a pure gum vulcanizate of SBR has a tensile strength of no more than 2.5 MPa, and almost nonexistent abrasion resistance, compounding it with 50% of its weight of carbon black improves its tensile strength and wear resistance as shown in the below table.
NON-BLACK FILLERS FOR ELASTOMERS ... Carbon black is the major reinforcing filler for tires and many other rubber and plastic products. However, carbon black impose a restriction on the color of the vulcanized products. On the other hand, non-black fillers ... − increased resistance to abrasion;
The total filler content was 50 phr and the filler compositions were carbon black 50phr itself, and multi-wall carbon nanotubes (MWCNTs)/carbon black (CB) = 10/40 phr, respectively. Additionally, the filler ... Fig.3 Abrasion Resistance of the mixture 1, 2, and 3 In order to improve abrasion resistance on the roads, we applied MWCNTs, and f ...
Ratio CB/Si 40/20 gives an optimum filler blended. It is also clearly understood that higher abrasion resistance mainly due to the lower hardness value under the same condition. The tensile stress at 300% elongation of rubber compound increased with the increasing carbon black filler.
This new Carbon Black filler system significantly reduces the energy loss of a tire tread compound and therefore the tire rolling resistance. This increases fuel efficiency and reduces the tire's carbon footprint. These products have also demonstrated cutting-edge abrasion resistance in .
Also, the flexing resistance of CaO-AC (0.007 mm/kc) has been found to be better than carbon black filler, whereas the abrasion resistance (173%) is slightly higher than carbon black filler.
The top filler materials used are ground calcium carbonate (GCC), precipitated calcium carbonate (PCC), kaolin, talc, and carbon black. Filler materials can affect the tensile strength, toughness, heat resistance, color, clarity etc. A good example of this is the addition of talc to polypropylene.
enhancement of strength and strength-related properties, abrasion resistance, hardness and modulus. In most applications, carbon black (C B) and silica have been used as the main reinforcing fillers that increase the usefulness of rubbers. When CB is compounded with rubbers, tensile strength, tear strength, modulus and abrasion
Physical properties like abrasion resistance, tensile and tear are moderately, ... carbon black and how they relate to the rubber's final properties. By tweaking either property or ... the requirements be met with in-house blacks or should a special black be considered to optimize FILLERS/ EXTENDERS
the most common hydrocarbon used in the manufacture of carbon black. Carbon black has many applications in plastics. It is used as a pigment, conductive filler material, particulate reinforcement, and ultraviolet light (UV) absorber. In rotomolded tanks CB is used both as a pigment and as an ultraviolet light absorber. Carbon black
improvement of processing as well as vu1canizate properties, such as, tensile strength, abrasion resistance and flex crack growth resistance. Modification of carbon black filler and subsequent evaluation of its reinforcing action in different synthetic and natural rubbers have long been a subject of study of many researchers. Grafting of
CORAX® N660 carbon black (35 m 2 /g - Nitrogen surface area) is used as reinforcing filler in tire tread compounds, primarily truck tires, mechanical rubber goods. Offers very good abrasion resistance. Provides good tear resistance and high tensile strength.
