APEL™ APL5514ML

APEL™ APL5514ML by Mitsui Chemicals is a high density, amorphous, norbornene-type cyclo olefin copolymer (COC) resin. Is non polar, optically isotropic and is developed using Ziegler polymerization technology. Possesses excellent dimensional stability, good melt processability, flowability, good clarity, excellent electrical insulating properties and transparency. Offers high glass transition temperature (Tg), exceptional moisture impermeability and impressive gas barrier qualities. Exhibits outstanding moisture resistance, excellent chemical-, acid-, alkali-, alcohol-, ketone-, ester-, humidity and heat resistance. Provides low coefficient of linear expansion, good thermal, dielectric & electrical behavior, low shrinkage and low moisture absorption. Shows a light transmittance (91%), lower birefringence (less than 5 nm) and the highest refractive index (1.54) among commercialized COCs and other cyclo olefin polymers. Is suitable for processing by injection molding or extrusion. APEL™ APL5514ML is recommended for highly reliable optical parts.
