Novus 21 Pressure/Temperature Limits

1. Suitable subject to chemical compatibility.
2. Suitable in some cases but check your application requirements with Flexitallic.
3. Contact the Technical Team for applicatis on with higher temperatures and pressures. Applicable to 1.5mm and below.

The operating temperature of non-asbestos sheet material is related to the thickness of materials selected. Thinner materials give better temperature and pressure properties.
