| Product Description TOPAS Elastomer E-140, unlike most TOPAS grades, is a semicrystalline cyclic olefin material with flexibility. It is a fairly stiff elastomer which can be extruded and injection molded, and can be blended with other TOPAS grades, other olefin resins and elastomers. For an elastomer, E-140 features high moisture barrier and has excellent clarity in thin sections or films. Secondary Tg of -6°C is relatively insignificant in terms of E-140 properties such as low temperature brittleness. The major Tg is below -90°C, while the melting point is about 84°C. Selected Applications High toughness film (as COC blend) Tubing Bags Overmolding Food packaging Food contact Leading Attributes Toughness, clarity, stiffness, low WVTR, reclaimability Purity, kink resistance Purity, olefin compatibility, cold resistance Adhesion to olefins, purity, soft feel Not manufactured with BPA, phthalates, or halogens Broad regulatory compliance&& |
