A noise, vibration, harshness (NVH) mitigation material comprising a non-metallic woven fabric substrate impregnated with a resin and one or more elastomeric layers applied to at least one surface of the non-metallic woven fabric substrate is disclosed herein. A method to fabricate a noise, vibration, harshness (NVH) mitigation material comprising preparing an impregnating resin comprising a resin and one or more of a filler and a toughening agent; impregnating a non-metallic woven fabric substrate with the impregnating resin by soaking the non-metallic woven fabric substrate with the impregnating resin, drying the impregnated non- metallic woven fabric substrate, and curing the impregnated non-metallic woven fabric substrate; and applying one or more elastomeric coatings onto the impregnated non-metallic woven fabric substrate is also disclosed herein.

The dynamic fatigue and hysteresis performances of fiber reinforced rubber compounds are compared using different plasticizers. Polymer-based fiber reinforced rubber compounds including a non-linear functionalized fatty acid ester, preferably a trimellitate, and more preferably Tris (2-Ethylhexyl) Trimellitate (TOTM) are shown to demonstrate greatly improved dynamic fatigue and hysteretic performance as compared to reference fiber reinforced rubber compounds including conventional reference plasticizers such as Di-isodecyl phthalate (DIDP).

Examples provide a method for manufacturing electrically conductive rubber matting. The method includes charging, into an internal mixer, a set of ingredients for forming a rubber compound. The set of ingredients include 63.2 weight percent (wt %) to 73.2 wt % nitrile rubber, 25.0 wt % to 35.0 wt % polyvinyl chloride (PVC) plastic, 0.02 wt % to 1.0 wt % PVC stabilizer, and 0.8 wt % to 2.6 wt % carbon nanostructures not including carbon black. The ingredients are mixed at a first speed at least until a measured temperature in the internal mixer reaches a first threshold temperature. The ingredients are mixed at a second speed that is greater than the first speed at least until the measured temperature in the internal mixer reaches a second threshold temperature that is greater than the first threshold temperature. After mixing, the rubber compound is discharged the rubber compound from the internal mixer and shaped.

The invention relates to a process for recycling at least one target polymer from plastic waste containing at least one contaminant.

A composition for accelerating aerobic biodegradation of an elastomer, such as NBR latex, comprises an additive that includes a monomer with a plurality of polyhydroxy groups, and a growth enhancer for aerobic bacteria. When combining the monomer and the growth enhancer in a weight ratio of between 12:1 and 6:1, the result is an assimilative carbon to nitrogen ratio in the elastomer of between 10:1 and 30:1. Preferably the monomer with the plurality of polyhydroxy groups has a molecular weight of between 140-180 g/mol, and the growth enhancer of aerobic bacteria has a molecular weight of between 130-140 g/mol. In some embodiments the composition is added to a base that results in an alkaline mixture, and a dehydrating agent to inhibit agglomeration and decomposition.
