Temperature Resistance – injection molding

TOPAS® cyclic olefin copolymer (COC) is available in grades with glass transition temperatures ranging from 65 to 178°C. Injection molding grades include:

Because TOPAS resin is amorphous, it maintains stiffness at elevated temperature far better than semicrystalline polymers 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. As an olefin, TOPAS polymer can be blended with PE or PP to enhance heat resistance.
