Quality benefits
- Positive gloss production (similar to cotton paper filled rolls).
- Excellent smoothing effect.
- Superior lustrous finish on fabrics when used in combination with a highly polished steel roll.
- Excellent densification of calendered product.
- Minimal dusting avoids contamination of calendered product.
Typical hardness - 87+/-1° Shore D
Maximum linear pressure - 450 kN/lm (2570 pli)
Maximum speed - 1000 m/min
Maximum surface temperature of heated steel roll - 360°C (680°F)
Maximum surface temperature of Nomex roll -200°C (392°F)
