About APEL™

Cyclic Olefin Copolymer

Have More Freedom in
Optical Design
Have Clearer View of the Future.

APEL™, cyclic olefin Copolymer of Mitsui Chemicals product,
is amorphous and transparent resin with excellent optical properties.
APEL™ has been contributing to “smaller and lighter lens design”,
with its highest refractive index and lowest birefringence among amorphous polyolefins,
and enables replacement of conventional lens materials such as glass or PMMA.
APEL™ maintains its performance in the severe environment such as high humidity, high temperature,
hence it is suitably adopted for new applications such as lenses for
Automotive Camera and Head Mounted Display (HMD).
In addition, APEL™’s excellence in moisture barrier, electric properties,
and chemical resistance has been perfectly fit for food and medical packaging.
APEL™ stays innovative and is fitting to various advanced market needs.
“Have Freedom in Optical Design, Have Clearer View of the Future”
is the key message of APEL™ to the industry and society.

Cyclic Olefin Copolymer

APEL™ is Cyclic Olefin Copolymer (COC) produced by copolymerization of ethylene and cyclic olefins. APEL™ has the highest refractive index and lowest birefringence among amorphous polyolefins.

It has various features perfect for optical lenses

As APEL™ is an amorphous, transparent resin with excellent optical balance,
so it can be used in all kinds of applications.

It Demonstrates its Excellent Functionality in All Kinds of Applications

Head Mounted Display
Automotive Camera Lenses
Medical packages

Sample Smartphone

Smartphone camera lens modules consist of several concave and convex lenses.
APEL™ is mainly used for convex and sensor-side lenses.

Sample Head Mounted Display

It is used for parts of heads-up displays (condenser lens, combiner, etc.)
and optical parts of AR/VR devices.

Sample Automotive Camera Lenses

APEL™ is used for Sensing camera, view camera, drive recorder,
back view monitor, head-up display, etc.

Sample Medical packages

APEL™ is used for PTP Packaging Sheets, Prefilled Syringes,
Pill Bottles, Inspection Containers
