The prevalence and severity of latex allergy has increased dramatically in the last 15 years due to exposure to natural rubber products. Although historically this health risk has been elevated in hospital personnel and patients, a recent survey has indicated a significant potential risk for the general population. To obtain a wide-spread source for latex exposure, we have considered tire debri...

The risk to adjacent aquatic systems posed by leachates from scrap tires used in engineering applications has not been characterized adequately. Toxicity testing, toxicity identification evaluation (TIE), and groundwater modeling were used to determine the circumstances under which tire shreds could be used as roadbed fill with negligible risk to aquatic organisms in adjacent water bodies. Elev...

Tire-tread material has a zinc (Zn) content of about 1 wt %. The quantity of tread material lost to road surfaces by abrasion has not been well characterized. Two approaches were used to assess the magnitude of this nonpoint source of Zn in the U.S. for the period 1936-1999. In the first approach, tread-wear rates from the automotive engineering literature were used in conjunction with vehicle ...

Among various dissipating mechanisms, the viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with improving the fuel consumption of vehicles and resultantly energy savage. Hysteretic loss is a fraction of...

Studies on increasing the level of yield have great importance for Russian Federation as a whole and Altai Territory in particular agro-industrial complex. LLC “NORTEC” developed implemented Flexible sidewall technology order to reduce tire pressure ground. An analysis external characteristics, composition tire, well impact its surface ground was carried out. It possible operating 0.8 kgf / cm2...

This report describes activity at a workshop on New Measurement Technology for Polymer Processing which was held at the National Institute of Standards and Technology on December 3-4,1990. The workshop was attended by 19 industry scientists and engineers from polymer processing and instrumentation manufacturing companies. The objective was to seek industry responses to the question: what in-lin...
