BLACOH's new high pressure PVDF dampener models are constructed with both the wetted and non-wetted
bodies in PVDF (Kynar®), and are generally less expensive than comparable
stainless steel models necessary for higher pressure applications.
PVDF plastic is strong, highly chemical resistant and operates at temperatures
up to 285°F (140°C). Extensive pressure testing at ambient temperatures has
demonstrated that these higher pressure ratings are justified, while still
maintaining a better than 4 to 1 safety margin at burst pressure.
Caution must be used at elevated temperatures — even though PVDF is more stable
than most plastics at elevated temperatures, PVDF loses strength as temperature
increases.
