Traditional internal mixing techniques for natural rubber (NR) and silica leave room for improvement in achieving good polymer-filler interaction in TBR (truck and bus radial) tread compounds. Internal, solid phase mixing of NR polymer and precipitated silica is complicated by several factors.
Read MoreThe sidewall typically extends from the exterior of the bead area to the shoulder of the tire. This component in a tire has three functions;
Protect the side of the tire from damage due to curbs or other foreign objects.
Due to flexing as the tire passes through its loaded footprint, it must also demonstrate fatigue and aging resistance and protect the tire casing
Via lettering on the sidewall, provide structural information (plies, belts, load carrying capacity) and other regulatory information such as place and date of manufacture, and if needed, white strips (white sidewall), raised white letters, the tire brand or model and name of the manufacturer.
Industrial grade silicone rubber compounds whose precursors are derived from plant based raw materials will be introduced by Wacker at K 2022, the international trade fair for plastics and rubber taking place in Düsseldorf, Germany, October 19- 26. Wacker will unveil several biomethanol based product lines under the Elastosil eco umbrella, including one liquid and six solid silicone rubber grades, as well as selected Silmix silicone rubber compounds.
Read MoreThe origins for modern project management stem from the late 1950s, where the methodology was applied in aerospace, defense and construction. With the advent of IT (information technology), a formalized system of project management was developed and has taken a foothold in nearly every business. With the recent initiative to onshore glove manufacturing to the U.S., project management has now become a central framework for the construction, equipment validation and manufacturing initiatives which underpin U.S. based glove manufacturing capabilities.
Read MoreSeveral products that can serve more than one purpose in rubber compounds are examined, including anti-reversion agents, dithiophosphates, curing activators and blowing agents.
Read MoreMathematical models are used to better understand and quantify the effect of HNBR polymer characteristics, including degree of polarity, molecular weight and residual double bonds on the mechanical and dynamic properties of peroxide cured compounds.

Performance of a novel sustainable oil specially developed for the tire industry is studied and compared with typical oils in typical S-SBR/BR tire tread formulations
with carbon black and silica/silane. In terms of mechano-dynamic properties, a shift of the maximum tangent delta towards lower temperature is observed.
Adhesives have been described as the diplomats of the rubber world, bringing materials together. Adhesion promoters help facilitate this process. To extend this metaphor, if adhesives are the diplomats, tackifier resins are the handshake that binds the agreement within rubber. These additives are generally medium molecular weight chemicals that are added to rubber compounds, altering their properties by imparting improved tack.
Read MoreThe United States has almost 1 million oil producing wells, and most require the use of an artificial lift system. There are various methods of artificial lift which are utilized to increase pressure within the reservoir to push oil to the surface. This allows operators to enhance production and extend well life.
