Platen seals are critical to bulk melter systems. The PFA encapsulation withstands the high temperatures required to melt solid adhesives, while the silicone core provides elastomeric resistance to allow the flow of media without leakage.
Vulcan Seals platen seals are manufactured and inspected to the highest quality standards to provide maximum sealing performance and reliability.
We can meet any of your PFA Platen Seals requirements for heated bulk melter applications.
Guaranteed best service, quality and value
