| Characteristics and applications |
|
| Particularly good electrical and mechanical properties by continuous use, even at high temperatures. Very good chemical resistance. Construction and insulation material in electrical machinery, transformers and chemical plants. Suitable for mechanical applications, e.g. as wear parts/vanes in oil-lubricated vacuum pumps. The flexural strength and modulus of elasticity values are measured lengthwise the sheet. |
