What is the Material Compatibility Chart for Plastic?
Key to Materials Compatibility
| S | Satisfactory for use with the intended gas. |
| C | Conditional. May be incompatible under some circumstances or conditions. Contact your Linde representative for additional information. |
| U | Unsatisfactory for use with the intended gas. |
| I | Insufficient data available to determine compatibility with the intended gas. |
| O | All nonmetallic, even those considered compatible, may be ignitable in oxygen enriched environments or in other oxidizing gases. Successful use depends upon oxygen purity, pressure, temperature, cleanliness and elimination of ignition mechanisms. Please contact your Linde Representative for additional information. |

Note: These charts have been prepared for use with dry (anhydrous) gases at normal operating temperature of 70 °F (21 °C). Information may vary if different operating conditions exist. Systems and equipment used in oxidizer gas service (e.g., Oxygen or Nitrous Oxide) must be cleaned for oxygen service.
