Created in the 1990s, COC (Cyclic Olefin Copolymer) and COP (Cyclic Olefin Polymer) polymers quickly gained attention for their exceptional clarity, rivaling even glass in their transparency. But their story doesn't end there. 
But what truly sets these polymers apart is their versatility. COC and COP can adapt to diverse needs, finding homes in industries ranging from healthcare and electronics to aerospace and automotive. From life-saving medical devices to high-tech displays, these polymers are making their mark on the modern world.
In this article, we'll explore their diverse uses, highlighting the benefits they offer across various sectors. So, get ready to discover the hidden potential of these remarkable polymers!

1. Comparison between COC and COP

1.1. Availability and cost

COCs, due to their slightly simpler composition, are often less expensive than their more expensive COP cousins. However, this does not imply that they are inexpensive by any means. Both materials are considered high-performance, so expect them to be more expensive than standard plastics.
COCs have a modest advantage in terms of availability. They've been around longer and have more suppliers. Major chemical companies like DuPont and Topas specialize in COC production, while COP production is still dominated by a few key players like Zeon Corporation and Mitsui Chemicals.

1.2. Optical properties

Both COC and COP are masters of transparency, allowing light to pass through with incredible clarity. While COPs have superior transparency, COCs are still significantly more transparent than many other commonly used polymers like PET or PMMA. This makes them suitable for various applications requiring good optical clarity.

1.3. Mechanical properties

Strength and durability are essential qualities for many applications, and both COC and COP deliver in spades. They are both incredibly strong and resistant to impact, making them ideal for structural components and demanding environments. However, COP edges out COC slightly in terms of stiffness, making it the clear winner for applications requiring unwavering rigidity.

1.4. Chemical properties

COC and COP exhibit exceptional chemical resistance, including acids, bases, and organic solvents. Medical devices and food packaging will make the best use of COC and COP since they require good chemical compatibility. COC, on the other hand, may be more resistant to strong acids and oxidizing agents than COP.

1.5. Thermal properties

COC and COP can maintain their properties at high temperatures exceeding 150°C. However, COP generally possesses a higher heat deflection temperature (HDT) compared to COC, approximately 10°C to 30°C, indicating its capacity to endure higher temperatures without distortion.
Let us proceed with this comparison chart of key differences between COC and COP.
