Topas Elastomer E-140
Elastomer E-140
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.
