Enhances Optical Design Freedom
Multi-functional, Transparent Resin.
APEL™ has excellent optical balance.
High Refractive Index
Even among amorphous polyolefins, it boasts the highest refractive index, and offers superior correction of aberration.Due to the high degree of design freedom, it is commonly used in devices like smartphones and is ideal for highly transparent optical lenses and components.
《 Refractive index and Abbe’s number 》
By its nature, APEL™ has little optical anisotropy or birefringence.With excellent AR coating properties, it is even used in fields like head-mounted displays (HMD).
《 Test Results (Comparison with COP) 》
High light transmittance in the visible light range (400 to 800 nm).
《 Transparency 》
High Heat Resistance
The substance is resistant to yellowing and deformation, even under high temperatures. Little thermal dependency in its mechanical properties.
《 Heat Resistance 125℃ Test Results》
《 Change in Refractive Index 》
High Moisture Resistance
With the lowest moisture permeability coefficient among transparent resins, it is ideal for packaging materials that demand moisture resistance.
《 O2 Transmittance and Moisture Permeability 》
Its non-crystalline nature gives it excellent dimensional accuracy that does not change due to water absorption. Compared to PC, APEL™ absorbs little moisture and is excellent in terms of dimensional stability.
《 Dimensional Rate of Change due to Water Absorption 》
It has excellent electrical characteristics, a fundamental feature of polyolefins, as well as excellent high-frequency characteristics.
《 Dielectric loss and Dielectric constant 》
As it is chemically stable, it demonstrates high chemical resistance to acids, alkalis and polar solvents.
《 Comparison with Various Resins in Chemical Resistance 》
