Material Notes:
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, olefin resins and elastomers. For an elastomer, E-140 features high moisture barrier and has moderate 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. Primary Tg is below -90°C, while the melting point is about 84°C. Key applications and attributes: High toughness film (as COC blend): Toughness, clarity, stiffness, low WVTR, reclaimability Tubing: Purity, kink resistance Bags: Purity, olefin compatibility Over-molding: Adhesion to olefins, purity, soft feel Food packaging: Not manufactured with BPA, phthalates, or halogens Food contact: Broad regulatory approval Note: 125µm film data includes 1% Ampacet 102765 1.5:1 BURInformation provided by TOPAS Advanced Polymers
