In general, polymer/solvent solutions exhibit elongational or honey-like stringing properties caused by polymer chain entanglement.
This stringing phenomenon causes processing and quality problems in production.
S-LEC SV is a resin specially formulated to prevent stringing.
Comparison data for S-LEC SV and PVB solutions are shown in Fig. 1.
Conventional PVB solution strings readily, while S-LEC SV has low stringing properties which vastly improve processibility.
