Frequently Asked Questions

Q: What makes the Doniflon 2020 different from standard PTFE gaskets?

Doniflon 2020 features enhanced structural reinforcement that significantly reduces "cold flow" or creep, which is a common failure point in standard PTFE gaskets.

Q: Can these gaskets be used for highly acidic chemical lines?

Yes, because of the high-grade PTFE base, Doniflon 2020 is chemically inert and suitable for almost all corrosive acids and bases.

Q: How do I determine the correct size for my flange insulation kit?

We recommend providing your flange standard (e.g., ANSI, DIN, JIS) and the nominal pipe size (NPS) to ensure a perfect fit.

Q: What is the typical temperature range for Doniflon 2020?

It is designed to operate efficiently across a broad spectrum, from cryogenic temperatures up to several hundred degrees Celsius, depending on the pressure.

Q: Is this product compatible with pharmaceutical grade requirements?

Yes, PTFE is non-toxic and non-reactive, making the Doniflon 2020 suitable for applications where purity is critical, such as pharma and food processing.

Q: Do you provide custom shapes for specialized rubber and plastic parts?

Absolutely. We specialize in precision cutting and fabrication of gaskets to meet exact customer drawings and technical specifications.
