In recent years, it has also been shown that the plasticizing oil plays an important role in tire performance (ref.
In this study, we have chosen plasticizing oils having similar molecular weight, and we will investigate the effect of the oil's chemical composition on the performance of tire tread compounds.
Key statement: A thermoplastic composition that includes from about 1% by weight to 25% by weight block copolymer having the formula (A-B)x or A-B-A, where the A block includes polyvinylarene, the B block includes poly(monoalkenyl) and x is an integer of at least one, spherical superabsorbent particles comprising polyacrylate, and plasticizing oil
, the composition exhibiting water gel time of no greater than two minutes, a viscosity of no greater than 100,000 centipoise and a wet tensile strength of at least 15 g/[in.
The interpretation revealed that the hose spectra were consistent with a chlorinated polyethylene rubber compound that contained trimellitate-based plasticizing oil and talc filler.
This represented the evolution of trimellitate plasticizing oil, combined with the dehydrohalogenation of the chlorinated polyethylene.
Regarding the leaching of the trimellitate plasticizing oil used in the failed hose, it is judged that a chemical was present in the fuel that had more of an affinity or similar polarity with the trimellitate oil than the chlorinated polyethylene, therefore leaching it from the compound.
The second part of this handbook provides guidance on how to select the right naphthenic plasticizing oil
X-743 and aromatic oil 745 are dark-colored, medium-viscosity plasticizing oils
NP-10, NP-25 and CB-4-34 and LX-1235 plasticizers are viscous materials with Ring and Ball softening points of 50 F, 77 F, 82 F, and 91 F, respectively, X-743 and aromatic oil 745 are dark-colored, medium-viscosity plasticizing oils
While the influence of different plasticizing oils on SBR compounds has been studied by different sources (refs.
In this article, we will discuss how the use of different plasticizing oils modifies the properties of a truck tire tread compound based on natural rubber.
Quite often, process aids, lubricants and partial amounts of plasticizing oils
are added in the mastication zone.
