制冷剂R22、R32价格持续上涨，军民两用刺激UHMWPE需求增加

Investment Rating - The report maintains a positive outlook on the basic chemical industry [1] Core Views - The prices of refrigerants R22 and R32 continue to rise, driven by supply concerns and increasing demand from both military and civilian applications for UHMWPE [1][5] - The demand for phosphate monoammonium (MAP) is increasing due to the spring farming season, with prices rising as a result of higher sulfur costs [3][4] - The report suggests focusing on companies such as Juhua Co., Sanmei Co., and Yonghe Co. in the refrigerant sector, and Tongyi Zhong in the UHMWPE sector [5] Summary by Sections 1. Key Chemical Product Price Tracking - The report tracks 58 monitored products, noting significant price increases for R22 (4.41%), light soda ash (2.29%), and methanol (2.29%), while declines were observed in acrylic acid (-5.52%) and TDI (-5.50%) [14][15] 2. Refrigerants - The report highlights that the refrigerant market is entering a demand peak, with prices and margins for major refrigerants on the rise. As of March 9, R22 is priced at 35,500 CNY/ton, up 1,500 CNY/ton from the previous week [4][5] 3. UHMWPE - The demand for UHMWPE fibers is steadily growing in military applications, with potential for increased demand in humanoid robotics and other technological fields [5] 4. Fertilizers - The price of phosphate monoammonium has risen to 3,316 CNY/ton, reflecting a weekly increase of 37 CNY/ton, while phosphate diammonium is priced at 3,338 CNY/ton, up 32 CNY/ton [3][4] 5. Polyurethane - MDI prices are declining due to limited acceptance of high prices by downstream enterprises, while TDI faces supply pressure with abundant market inventory [17][18]
