product description
topas elastomer e-140, unlike most topas grades, is asemicrystalline cyclic olefin material with flexibility. it is afairly stiff elastomer which can be extruded and injection molded,and can be blended with other topas grades, other olefin resins andelastomers. for an elastomer, e-140 features high moisture barrierand has excellent clarity in thin sections or films. secondary tgof -6°c is relatively insignificant in terms of e-140 propertiessuch as low temperature brittleness. the major tg is below -90°c,while the melting point is about 84°c.
