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 cuttingedge abrasion resistance in .
Jun 01, 2012· Home » Recent Developments to Improve Scratch and Mar Resistance ... is much more limited even though alumina is significantly harder than silicabased materials and as a scratch and abrasionresistant filler, ... becomes more and more important. For many decades, lowcost fillers (, those based on CaCO 3, clay, quartz and carbon black) ...
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.
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 ...

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.
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.
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 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.
This invention relates to a tire with a tread of rubber composition with reinforcing filler containing oxidized rubber reinforcing carbon black together with tris (2ethyl 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 1,4polyisoprene rubber containing reinforcing filler ...
enhancement of strength and strengthrelated 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
Improving the Abrasion Resistance of "Green" Tyre Compounds Teku Zakwan Zaeimoedin1,2, Jane Clarke1 1Loughborough University, ... The greatest advantage of using silica over carbon black as a reinforcing filler in a tyre tread compound is that a lower rolling resistance is achieved, while maintaining good wet traction. However, a previous ...
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.
NONBLACK 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, nonblack fillers ... − increased resistance to abrasion;
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 Effects of Silica/Carbon Black Ratio on the Dynamic 1103 good abrasion resistance and in addition, as the size of carbon black particles decreased and became close to nano size, the strength of the samples increased. Since tire is a composite structure made of .
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 inhouse blacks or should a special black be considered to optimize FILLERS/ EXTENDERS
NonBlack Compounds Choosing a reinforcing filler to replace carbon black for developing new nonblack rubber products can be a difficult process. Physical properties for your black compound, like low compressionset and heat buildup, along with good abrasion resistance and tensile strength need to be similar for your new one.
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
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.
Carbon fillers, especially carbon black as a reinforcing filler, are widely used ... abrasion resistance, tensile properties, and swelling resistance of the XSBR vulcanizates were systematically studied. 2. Experimental Materials XSBR latex KSL 103 was provided by the KumHo Petrochemical Company, Korea. RBC with a particle size of 53 μm
Orion Engineered Carbons has developed a new line of surfacemodified carbon blacks for rubber applications. According to the supplier, the new filler system greatly reduces the energy loss of a tire tread compound and therefore the tire''s rolling resistance. The surfacemodified carbon blacks also exhibited extremely high levels of abrasion resistance in laboratory evaluations.
The total filler content was 50 phr and the filler compositions were carbon black 50phr itself, and multiwall carbon nanotubes (MWCNTs)/carbon black (CB) = 10/40 phr, respectively. Additionally, the filler ... Abrasion Resistance of the mixture 1, 2, and 3 In order to improve abrasion resistance on the roads, we applied MWCNTs, and f ...
