Development and evaluation of military track pads

The U.S. Army utilizes the A3 Bradley Fighting Vehicle (BFV) as a tactical asset in combat and peace operations. Track failure on Army systems, such as those in Bradley Fighting Vehicles, is a significant cost driver for the Army. In-field track failures result in the entire platoon being mobilized to protect the vehicle and crew, putting warfighters at risk in hostile areas. A track’s main failure mode is typically related to specialized rubber components, such as elastomeric bushings, backer pads, track pads and road wheels.

Nepheline syenite as the smart alternative to crystalline silica fillers in silicone elastomers

Nepheline syenite is a silica deficient functional filler and additive widely employed in a variety of polymers, adhesives, coatings, inks and colorant applications. Micronized sizes are valued for purity of color, gloss control, antiblocking in polyolefin films and coatings, and ease of dispersion, with low viscosity build, abrasion and superior weather resistance

Effect of silane loading in a silica filled tread compound

Prior work has studied a range of polymer types and filler types to understand the effect of filler-polymer interaction on abrasion. A series of model compounds was studied, including three polymer types and two filler types. The polymer types were E-SBR, S-SBR and F-S-SBR. This allowed for the examination of the effect of polymer-filler interaction strength.

Environmentally friendly plasma black as drop-in replacement for furnace black

Monolith manufactures an environmentally friendly carbon black that results in two tons less CO2 emitted for every ton of carbon black produced. This carbon black has the same physical and colloidal properties as the incumbent furnace black, a process that was developed approximately 80 years ago. Monolith carbon black is manufactured using natural gas and renewable electricity, as opposed to pyrolysis fuel oil (PFO), so the product is a cleaner, more pure form of carbon black which is either a drop-in replacement for furnace black or very close in performance in rubber compounds. This article will explain the environmental advantage and present the physical properties as well as the performance data in rubber for Monolith’s new to the market plasma carbon black.

Silanized aluminum trihydroxide as a green filler for improvement in the tire performance

A wide variety of rubber compositions is used in the tire industry. The base elastomers that are commonly used consist of blends of natural rubber (NR), butadiene rubber (BR) and styrene-butadiene rubber (SBR). It is apparent that the utilization of rubber without filler does not provide good properties for any application.
Therefore, filler is used to impart better properties to rubber products, with carbon black or silica used commercially. Other ingredients with different functionalities are also incorporated into rubber compounds, depending on the application; i.e., softeners, vulcanizing agents, accelerators, activators, retarders and antidegradants.
