Frequently Asked Questions
Q: What makes Modified PTFE different from standard PTFE gaskets?
Modified PTFE, such as the Doniflon 2020, is engineered to reduce "cold flow" or creep, meaning it maintains its thickness and sealing force much better than standard PTFE over time.
Q: In which industries is the Donit Doniflon 2020 most commonly used?
It is widely used in the rubber and plastic parts industry, chemical processing plants, pharmaceutical labs, and petrochemical refineries due to its chemical inertness.
Q: Can these gaskets handle highly corrosive acids?
Yes, Modified PTFE is virtually inert to almost all known chemicals, making it one of the safest choices for highly corrosive acidic environments.
Q: Do I need to retighten Modified PTFE gaskets frequently?
Significantly less than standard PTFE. The modified properties drastically reduce the need for periodic retightening, reducing maintenance labor costs.
Q: Is the Doniflon 2020 suitable for high-pressure applications?
Yes, because it resists deformation (creep) under load, it is far more suitable for high-pressure sealing than virgin PTFE.
Q: How do I specify the size for a custom Modified PTFE gasket?
You can provide the Inner Diameter (ID), Outer Diameter (OD), and thickness, or specify the standard flange size (e.g., ASME or DIN standards).
