Cyclic olefin copolymer (COC) production capacity is concentrated in Japanese companies and is still in the early stages of development domestically.

Cyclic olefin copolymer (COC) is a non-crystalline transparent copolymer with a cyclic olefin structure formed by the copolymerization of bicycloconene (norbornene) monomer and ethylene monomer under the action of metallocene catalyst. It is a new type of high-performance polymer. Value-added thermoplastic engineering plastics with high transparency, high heat resistance, low density, low dielectric constant, low hygroscopicity, light specific gravity, resistance to polar solvents, acid resistance, alkali resistance, salt resistance, good adhesion, and high surface hardness , outstanding processability and other advantages, it can be widely used in optics, medical, packaging and other fields.

Among them, in the field of optics, cyclic olefin copolymer (COC) is used in various types of lenses, mobile phone display films, etc. due to its high transparency, strong ultraviolet penetration, low birefringence and good refractive index stability. Production. In the medical field, cyclic olefin copolymer (COC) has excellent transparency, water vapor barrier and biocompatibility, and is less dense than glass, so it is very suitable for making blood storage containers, test tubes, and Petri dishes. , syringes, pipettes, etc.

In the field of packaging, LLDPE is blended with COC to form a film, which can increase the modulus, improve the film sealing strength, shrinkage performance, and gas barrier properties. It is used for packaging of food, medicine, etc. In addition, COC/PCTFE high-barrier blister film is an extremely Best pharmaceutical packaging materials.

From the perspective of cyclic olefin copolymer (COC) production, according to the” Cyclic Olefin Copolymer (COC) Industry Depth 2022-2026″ released by the Industrial Research Center Market Research and Investment Strategy Suggestion Report shows that the current cyclic olefin copolymer (COC) production technology is mainly controlled by Zeon, Japan Synthetic Rubber Company (JSR), Polyplastics Co., Ltd., and Mitsui Chemicals, Topas Advanced Polymers and other Japanese companies. In addition to Japanese companies, the domestic Wuxi Akoli Technology Co., Ltd. has opened up the cyclic olefin copolymer (COC) process route and completed the preparation of kilogram-level COC samples.

From the perspective of the demand side of cyclic olefin copolymers (COC), the demand for cyclic olefin copolymers (COC) in the Asia-Pacific and EU regions is relatively large. In 2021, the total demand for cyclic olefin copolymers (COC) in the Asia-Pacific and EU regions will account for More than 70%. From the perspective of demand, in 2021, the global market demand for cyclic olefin copolymers (COC) will exceed 100,000 tons.

Industrial analysts said that the cyclic olefin copolymer (COC) industry has a high technical threshold and is still dominated by Japanese companies at this stage. status, domestic enterprises still need to make further efforts to break the existing competitive landscape of cyclic olefin copolymers (COC). In addition, the current manufacturing cost of cyclic olefin copolymers (COC) is still relatively high, which to a large extent limits the increase in application demand for cyclic olefin copolymers (COC). In addition, downstream users in the fields of optics, medical care, packaging, etc. The performance advantages of cyclic olefin copolymers (COC) are not well understood, which also limits the development and growth of the cyclic olefin copolymer (COC) industry.
