Topas Advanced Polymers TOPAS® Elastomer E-140 Developmental Cyclic Olefin Copolymer (COC)

Categories:  Polymer; Thermoplastic; Cyclo Olefin Polymer
 
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
