Freudenberg Sealing Technologies has developed a new sealing system for busbar sealing in vehicle air-conditioning compressors. This elastomer-based solution withstands test pressures of over 100 bar in leak tests and offers a cost-efficient alternative to conventional glass seals. Designed for CO₂ compressors (R744), it also works well with other refrigerants.

Seen in such applications as medical defibrillators, polymer capacitors are responsible for quick bursts of energy and stabilizing power rather than holding large amounts of energy, as opposed to the slower, steadier energy of a battery. However, current state-of-the-art polymer capacitors cannot survive beyond 212 degrees Fahrenheit (F), which the air around a typical car engine can hit during summer months and an overworked data center can surpass on any given day.

applications
The 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.

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

The Type E mounted tapered roller bearing incorporates SKF’s CR Seal, which extends service life by virtually eliminating ingress of contamination, even under harsh conditions
Read MoreCDI 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).
