Material Notes:
PEARLTHANE® 18VT80 is a polyether based TPU, supplied in form of translucent, colorless pellets, combining hardness with excellent mechanical properties and superior hydrolysis and microbe resistance. PEARLTHANE® 18VT80 features a high moisture vapor transmission. PEARLTHANE® 18VT80 can be used for blown- and cast films for a wide variety of applications such as textile lamination. In addition, specific masterbatches for thin films are available. We strongly recommend the use of Pearlthane® MB52BK to ease the processing of this grade.All information provided by Merquinsa
