Given the wide variety of industrial environments that control electronics are exposed to, prevention of all environmental degradation mechanisms during use can be a challenge.
Curing of fluoroelastomers (FKM) can be accomplished commercially by three separate systems.
Hydrin-brand ECO has a long history of use in automotive applications due its exceptional heat and oil resistance up to 150°C, while maintaining flexibility at low temperatures down to -50°C.
This paper reports an overview of several different polybutadienes with different molecular architecture and related property-structure relationships.
The objective of this study is to determine how attributes of accelerators impact various aspects of cure-activation energy, cure rate, cure time and other properties. Six different main accelerators were utilized, all in conjunction with TMTD and the rubber maker’s sulfur in an efficient cure system and evaluated using Alpha Technologies’ Premier Rubber Process Analyzer and Enterprise software.
Throughout the last 10 years, Molecular Rebar Design has been developing a new form of commercially available multi-wall carbon nanotubes that result in dispersed individual, discrete, carbon nanotubes, marketed under the Molecular Rebar brand. Recent developments have led to rubber compound design that could address the tire performance needs for the premium tire segment, including the rapidly emerging electric vehicle market.
The fully saturated hydrocarbon backbone of EPDM rubber results in outstanding weatherability, ultraviolet stability and low/high temperature resistance. Therefore, EPDM rubber has been established as the primary polymer choice for automotive sealing applications (both dense and sponge weatherstrip).
This paper uses a design of experiment to quantify some of the comparative advantages statistically for the RPA ASTM test methods.
Over the last three decades, the rubber process analyzer has evolved as the processability test instrument of choice for measuring and solving many rubber factory problems.
To better understand the damage endured by mechanisms during downhole simulation testing (rapid gas decompression testing, or RGD testing), three downhole formulations (FKM, HNBR and NBR) were evaluated.
