The tensile test is one of the most common physical measurements in the rubber laboratory. Evaluating the average or median stress-strain behavior for five replicate specimens gives a quick and [...]

This article is the second of a two-part study on hydrogenated nitrile rubber (HNBR) (refs. 1 and 2), a specialty elastomer used in demanding applications in the automotive, industrial, and [...]

In a four-person household, the washing machine is in operation about one and a half hours a day. On average, it washes, rinses and spins about 250 times a year, [...]

Material evaluation tests for this article were performed using the recently developed Dynamic Mechanical Yerzley Oscillograph (DMYO) (figure 1). Just like the Yerzley Oscillograph (YO) (refs. 1 and 2), the [...]

Tires have a major influence on the handling and stability performance of automobiles. All steering, braking and accelerating forces between a vehicle and the road are mediated by the tires. [...]

The hydrogenation of NBR rubber to form HNBR was the subject of a patent filed in the mid 1970s by Bayer AG (ref. 1). The manufacturing of HNBR involves emulsion [...]

Generally, mineral oil is the plasticizer of choice for rubber compounding and the ingredient most commonly used to improve processability of rubber compounds. It is inexpensive compared to other compound [...]

One of the most common problems facing compounders is that of achieving satisfactory dispersion of compounding ingredients in rubber. Poor dispersion can result in lower physical properties leading to product [...]

Although static mechanical properties have a great role in the service life of tire tread, enough attention should be paid to dynamic properties. In fact, wearing of tire along with [...]

Silpuran 2410 A/B, an addition-curing silicone, can be made harder or softer in the lower durometer A range by varying the mixing ratio of its two components. This gives manufacturers [...]

Predicting toughness At last fall's Rubber Division meeting, a paper was presented by John Vicic of FMC's Corporate Development Center in San Jose that was quite interesting. The paper, 'Dynamic [...]
