If the usage involves applications with high thermal requirements (-50 degrees C to +200 degrees C) and cleaning processes without steam sterilization, but with less aggressive media, then 70 VMQ
117055 is the ideal sealing material.
DBPH-50-EZD provided a clear VMQ compound with good dispersion and no opaque white specks, versus DBPH-50 containing calcium carbonate.
Once all the vinyl groups of VMQ are reacted, no significant increase in MH will be obtained.
As noted, due to the temperatures involved, the incumbent materials have traditionally been FKM, VMQ and FVMQ.
They were introduced to fulfill the performance deficiencies of standard ACM and/or AEM TDI hoses (150[degrees]C to 160[degrees]C) and provide a more cost-effective alternative to the more expensive current high-temperature solutions, such as FKM, VMQ and FVMQ hoses.
The typical construction for turbocharger hoses uses VMQ silicone with a fluoroelastomer liner (FVMQ fluorosilicone or FKM fluorocarbon).
In the case of liquid VMQ silicone, even with a price premium typically realized (vs.

Therban[R] grades are also being developed for engine sealing as an effective performance replacement for VMQ
silicone elastomer products that must be replaced as a result of LEV II (Low Emission Vehicle) regulations.
