PTFE Burst Pressure Theoretical Formula

PTFE burst pressure formua

The innate strength of fluoropolymers makes them an ideal choice for high pressure tubing components. But many factors play a part in the actual pressures that are specific to various applications. For this reason, Component Supply does not list a burst pressure rating for our fluoropolymer tubing products. This is a theoretical formula that can be used to yield the maximum burst pressure. We provide this theoretical formula as a reference to give engineers and researchers a place to start their testing. But it is the end user’s responsibility to safely test all products and Component Supply assumes no responsibility in applications putting these products under pressure.

**Please note that the equation provided is theoretical. It does not take into account certain factors such as steam pressure, temperature (calculated at room temperature), altitude and others. The result is only to be used as a guideline for design and testing purposes. It is not meant to yield a definitive number. Testing will be required to determine accurate and safe pressure limits**

    Tensile Strengths

  • PTFE – 2,500 psi
  • FEP – 3,000 psi
  • PFA – 4,000 psi
  • ETFE – 6,500 psi
  • PEEK – 13,000 psi

The Theoretical Burst Pressure equation can be used to solve for either pressure (P) or tensile strength (T), depending on what information you have available. If you know what material your tubing is, then you can calculate the burst pressure (P) of this tubing. If you are trying to decide what type of tubing you need and have the specific burst pressure (P) rating your application requires, you can use the desired burst pressure (P) and calculate a theoretical tensile strength (T) that can guide you to a material to start your testing.
