Pressure-Property Relationships in High-Performance Elastomers
… nitrile butadiene (HNBR), and fluoroelastomer (FKM), widely used in high pressure gas environments, have attracted significant interest from both fundamental research and industrial development. The changes in the glass transition temperature (Tg) and gas sorption behavior of elastomers due to …

The effect of hydrocarbon exposure and temperature on the behaviour of elastomeric seals
… set of investigations on fluorocarbon (FKM) rubber. No comprehensive study of the temperature sensitivity of fuel composition on swelling has been attempted prior to this study. NBR and FKM were swollen in petroleum Jet A-1, synthesised paraffinic kerosene (SPK) and a variety of blends …

Development of Multifunctional Polymer Nanocomposites with Hybrid Structures for Fabrication of Stretchable Strain Sensing and Wearable Electronic Devices
… introduced in CNT combined with fluoroelastomer FKM using an internal melt-mixing process. The two percolation networks provided wide range of low to high stretchability with high sensitivities. High strain sensing of more than 200% with high sensitivity or gauge factor (GF) of greater than …

Structure-Property Relationships of Flexible Polyurethane Foams
… fluoride-co-hexafluoropropylene) (FKM). This revealed that tensile and dynamic moduli could be predictably altered by controlling the degree of FKM cross-linking or by varying PTFE content in the film. Inducing PTFE fibrillation was found to yield higher modulus films without …

Design and Fatigue Analysis of an LWD Drill Tool
… the endurance limit. Shigley guidelines and FKM guidelines are compared as a part of a study to select the best possible approach in the current application. The width of the imaging pocket is varied from 1.25 inches to 2.0 inches to accommodate the largest possible transducer without …

Effects of O-Ring Elastomers with Conventional and Synthesized Aviation Fuels with a Novel Elastomer Dynamic Compression System
… research include investigating NBR, FVMQ, and FKM O-ring elastomer reaction with conventional Jet A, HEFA, ATJ, and synthetic aromatic kerosene individually along with blends of synthetic fuels with Jet A. Additionally, the complex pathway of fuel into the O-ring is investigated in conjunction …

Experimental investigation of the combined effects of corrosion and mean stress on fatigue strength of low carbon steel
… ratios, compared to trends in air. A modified FKM approach is proposed, based on the definition of mean stress sensitivity factor parameters, to predict the allowable stress up to 10^9 fatigue cycles in the freshwater environment.;Industry scale specimens were designed to reproduce critical …
