ULTRACAST is a multi-purpose casting sheet. It function well with PVC, PU and SEMI-PU (PU/PVC). It is designed to be compatible with solution, dispersions and latex systems.
ULTRACAST 100% pattern replication is a decided advantage for urethanes which compete head to head with real leather. No mechanically embossed release paper can compare with it.
ULTRACAST will always replicate the engraved roll perfectly. There is no gloss or depth variation roll-to-roll or run-to-run. The only way to change the gloss or the pattern depth is to change the engraved roll.
ULTRACAST is temperature stable. It performs well at PVC blowing temperatures and higher (200C+) Without any changes to film gloss and pattern depth.
Since ULTRACAST ‘s embossing pattern is contained totally within the hard ULTRACAST coating it can be used at pressures over 100 BAR with no loss of definition. This is especially importance in the “paper embossing process” where an ULTRACAST web is used, under heat and pressure, as an embossing mediumfor plastic webs. ULTRACAST is also used in the high pressure, low pressure, and continuous melamine laminate markets.
