| The NEW POLYFLON APV is a high specific gravity PTFE glass backed sheet manufactured using a proprietary process. Its superior surface smoothness and low chemical permeability compared to conventional PTFE glass backed sheets make it an ideal lining material. |
|
| Features of the lining material |
Features of APV-lined containers |
| High specific gravity unmatched by conventional lining sheets. |
Low chemical permeability extends container's useful life. |
| Very smooth surface on the side that comes in contact with chemicals. |
Ease of cleaning speeds up process preparation. |
| Excellent weldability. |
Good reliability of welded areas provides added safety against mechanical stress and change in temperature. |
| The New POLYFLON APV is an ideal lining for chemical storage tanks and transportation containers, especially, those used in the semiconductor industries. |
