다음의 사례에서 보듯이,
Field Test결과 종전의 4079,1050LF,2035 Compound로는 실패했던 사용환경에서
Spectrum 6375로 대체한 결과 내구성증가등의 만족스런 성능을 나타내었다.

New Kalrez® Spectrum™ Extends Seal
Life Especially in Mechanical Seals
|
| DuPont Dow Elastomers
has expanded the capability of traditional perfluoroelastomer
parts with KalrezR Spectrum™ 6375 to provide the
broadest range of performance and value in harsh
chemical processing environments. Kalrez Spectrum
6375 enables chemical processors to extend seal
life, lengthen mean time between replacement (MTBR)
and lower total operating costs. Because Kalrez
Spectrum 6375 was designed specifically for the
chemical process industry(CPI), it provides outstanding
performance in the most hostile chemical environments,like
sulfuric acid, ethylene oxide, steam and amines.
Mixed streams,a persistant problem for processors,
are readily handled by 6375.

Longer Seal
Life, Less Risk of Failure
|
| Through a combination of innovative
polymer technology and a patented curing system,
Kalrez Spectrum 6375 allows for a continuous upper
service temperature of 275°C (525°F). This high-temperature
performance, which is 56°C (100°F) higher than other
products claiming broad chemical resistance, guarantees
longer seal life with less risk of unexpected seal
failure. Today, chemical processors who use several
perfluoroelastomers to optimize chemical and thermal
performance, may simplify seal selection and lower
inventory cost by choosing Kalrez Spectrum 6375.
Chemical processors should be delighted by the performance
of 6375 and its lower cost. It is value-priced below
current Kalrez compounds and is available globally
from authorized distributors of Kalrez parts in
the most popular seal sizes. |
