TOPAS Advanced Polymers

Temperature and Heat Resistance - packaging and film

TOPAS® cyclic olefin polymer (COC) is available in grades with glass transition temperatures ranging from 33 to 178°C. Key packaging grades:

As an olefin, TOPAS polymer can be blended with polyethylene or polypropylene to boost heat resistance. Because TOPAS resin is amorphous, it maintains stiffness at elevated temperature far better than semicrystalline plastics such as PE or PP. TOPAS COC maintains high stiffness up to temperatures within 10 to 15°C of its Tg, a level at which semicrystalline materials will have as little as 20% remaining stiffness. Commercial uses include form-fill-seal structures, all-olefin sealant and flexible pouch films, and more.
