Introduction

Cyclic Olefin Copolymers (COC) are high-performance, amorphous thermoplastics derived from the copolymerization of cyclic olefins (such as norbornene) and linear olefins (typically ethylene). COC materials are known for their exceptional optical clarity, low moisture absorption, high stiffness, and excellent barrier properties, making them valuable in industries such as medical devices, packaging, optics, and electronics.

Unlike traditional polymers like polypropylene or polyethylene, COCs combine the processability of polyolefins with superior mechanical and optical characteristics, creating a versatile material suited for demanding applications.

Key Properties

• High Transparency and Gloss: Offers superior optical clarity comparable to glass or PMMA.

• Low Moisture Absorption: Ensures dimensional stability and barrier integrity in humid environments.

• Excellent Chemical Resistance: Stable against acids, alkalis, and polar solvents.

• High Stiffness and Rigidity: Retains structural integrity under stress.

• Low Density: Lightweight compared to traditional engineering plastics.

• Superior Gas Barrier: Provides excellent barrier against oxygen and water vapor.

• Thermal Stability: Withstands temperatures up to 170°C depending on grade.

• Biocompatibility: Suitable for medical and pharmaceutical applications.
