How does one go about selecting the proper grade of SoarnoL™?

You should select the grade of SoarnoL™ by the required barrier properties and the processing method to be used. For example, grades with a low ethylene content (for example, 29 mol%) offer better barrier properties at normal humidity than the grades with a high ethylene content (for example, 44 mol%). On the other hand, grades with a high ethylene content have a lower melting point than those with a low ethylene content and can generally be molded easily even at low processing temperatures. Other selection criteria include the melt flow rate (MFR). You should select the ideal MFR for the fabrication conditions.
