WebHowever, the reflection print standard allows a maximum storage temperature of 18°C (64.5°F) and a relative humidity of 30% to 50%. While these conditions are relatively cool and dry, they are not outrageously difficult to achieve for most collections. Under these storage conditions, both fiber and RC papers are expected to do very well. WebBorealis beta-nucleation technology yields PP-RCT resins with improved pressure resistance, especially at elevated temperatures. Pressure tests conducted in accordance with ISO 9080 demonstrate a 50-year service life of 5 MPa (725 psi) at 70°C (160°F) for pipe produced with Borealis PP-RCT resins, as compared to 3.2 MPa (465 psi) for
