Lanxess new prepolymer degrades in aqueous and hot applications for oil and gas

LANXESS is adding to its extensive range of polyurethane (PU) systems for the oil and gas industry with a new prepolymer: Adiprene® Degrade 80C AQ90A. It can be used to manufacture elastomer components that can be deployed in temporary challenging applications and break down by themselves in warm (from 50 to 93ºC) and wet environments after a defined period of time

Thermoplastic polymer has API 610 recognition

CDI Energy Products announced that its latest material to achieve API 610 recognition outperformed service life expectations under extremely corrosive sulfuric acid conditions. API 610 is the standard for centrifugal pumps for the petroleum, petrochemical and natural gas industries. CDI’s proprietary thermoplastic polymer composite, Dures 200, was the foundation for critical components developed for an API 610 vertical single casing diffuser pump (VS1) for a high production sulfuric acid plant. CDI’s material scientists and engineers collaborated with the pump OEM to custom design suction bell eye case rings, bowl eye case rings and bowl bushings which could sustain differential pressures of over 200 psi, coupled with an extreme temperature profile of -20°F to 105°F (-28.8°C to 40.55°C).

Seals prevent bearing damage in EVs

Freudenberg Sealing Technologies’ new generation electrically conductive seals prevent bearing damage caused by electrically induced corrosion, and also increase electromagnetic compatibility. Electric cars with drive systems that operate at 800 volts instead of the usual 400 can recharge in just 15 minutes, and produce enough power to drive several hundred kilometers. The power semiconductors in the inverter ensure that the direct current stored in the battery is converted into the alternating current required by the electric motor while driving. These power electronics are often positioned directly above the electric motor, and are also known as electric engine injection systems.

Sealing solutions offered for air and sea

In aerospace, demand has increased for actuator designs that meet and exceed more rigorous performance standards, while providing unprecedented safety and reliability. Some of these requirements, such as the fire and flammability resistance defined in ISO 2685 and RTCA DO-160, go beyond the use of standard hydraulic seal designs. These high temperature, challenging requirements significantly impact commercial aircraft engine safety, and often force the use of heavy, bulky, easily damaged and costly external fire shielding. As a result, Greene Tweed developed the Fireproof Hydraulic Seal (FPH Seal), which has been specifically engineered to meet this need and establish a shielding alternative.

Lamination technology for multi-layer hose

Fluoroelastomer lamination technology for multilayer automotive hose constructions is said to be ideal for use in high-pressure, high-temperature areas near the engine, where they are also exposed to NOx, SOx, engine oils or other aggressive automotive fluids. AGC Chemicals Americas՚ AFLAS FEPM fluoroelastomers can withstand continuous service temperatures up to 200°C and have excellent acid, base, amine and steam resistance.

Thermally conductive elastomer for EV parts

Freudenberg Sealing Technologies (FST) has developed a thermally conductive elastomer that combines seemingly contradictory properties: It conducts heat well, but is also electrically insulating. FST is already testing initial applications for charging sockets, control units and batteries in electric vehicles.
