The current market demand for isosorbide PC is still small, but the industry has great development potential.

Isosorbide PC, namely isosorbide polycarbonate (PIC), is a polymer with a rigid and chiral structure. Its special cyclic structure (two adjacent furan rings) makes this type of polymer unique Excellent optical properties, thermal stability, impact resistance, UV resistance and scratch resistance. The glass transition temperature (Tg) of isosorbide PC can reach 174°C, and the light transmittance is greater than 90%, both of which are higher than BPA-PC. Due to its excellent performance and potential to replace BPA, isosorbide PC has become a research hotspot in the field of polycarbonate.

At present, the only company in the world that has the ability to industrially mass-produce isosorbide PC is Japan’s Mitsubishi Chemical. The isosorbide PC-DURABIO launched by it is a material that is more suitable for use in large-scale vehicle display casings. It is expected to be more suitable by replacing glass components. Lighter, larger, more complex shapes. Driven by Mitsubishi Chemical and downstream manufacturers, the market application of isosorbide PC has made certain progress. However, overall, due to the high production cost and price of isosorbide PC, potential downstream users have tried and actually applied isosorbide PC. There are few industries and related companies, and they are mainly concentrated in the automotive field with high material requirements. In addition, due to the small market capacity, although many companies are involved in the research and development and trial production of isosorbide PC, except for Mitsubishi Chemical, they have not yet There are other companies entering the stage of large-scale mass production, and competition in the global isosorbide PC industry is extremely relaxed, which is also an important reason why the price of isosorbide PC is difficult to fall.

In China, compared with traditional polycarbonate (PC) products, isosorbide PC has not been developed for a long time, and due to the presence of rigid groups in the molecular chain, it is brittle and has poor processing performance. In addition, the product is expensive , severely limiting its industrial application. According to the released “2023-2027 Isosorbide PC Industry In-depth Market Research and Investment Strategy Suggestions Report“, domestic sales in 2022 The demand for isosorbide PC is less than 60 tons. From this point of view, the penetration rate of isosorbide PC in the downstream application market is extremely low. Correspondingly, the recognition of isosorbide PC products by downstream users is also very low.

Judging from the current development of the domestic isosorbide PC industry, due to the limitation of isosorbide PC market demand, there are currently no domestic companies producing isosorbide PC, and only a few companies and scientific research institutions are conducting technical research on isosorbide PC. , such as Changchun Dacheng Industrial Group and Chinese Academy of Sciences Chengdu Organic Chemistry Co., Ltd. The investment scale of the domestic isosorbide PC industry is relatively small.

Analysts believe that in the long run, with the reduction of isosorbide production costs and the continuous improvement of isosorbide PC industrial production technology With breakthroughs and developments and increasingly stringent environmental protection requirements, isosorbide PC is expected to occupy a place in the field of PC applications. However, in the short term, due to various factors such as immature production technology, high production costs, high product prices, and immature downstream application technology, the demand for isosorbide PC is still relatively limited.
